| 2 | ACTIVE VIBRATION CONTROL OF FINITE L-SHAPED BEAM WITH TRAVELLING WAVE APPROACH显示文摘In this paper,the disturbance propagation and active vibration control of a finite L-shaped beam are studied.The dynamic response of the structure is obtained by the travelling wave approach.The active vibration suppression of the finite L-shaped beam is performed based on the structural vibration power flow.In the numerical calculation,the influences of the near field effect of the error sensor and the small error of the control forces on the control results are all considered.The simulation results indicate that the structural vibration response in the medium and high frequency regions can be effectively computed by the travelling wave method.The effect of the active control by controlling the power flow is much better than that by controlling the acceleration in some cases.And the control results by the power flow method are slightly affected by the locations of the error sensor and the small error of the control forces. | Chunchuan Liu Fengming Li1 Wenhu Huang(P.O.Box 137,School of Astronautics,Harbin Institute of Technology,Harbin 150001,China) | 2010 | Acta Mechanica Solida Sinica2010，23，5： | 8 |
| 3 | Tuning of band gaps for a two-dimensional piezoelectric phononic crystal with a rectangular lattice显示文摘In this paper,the elastic wave propagation in atwo-dimensional piezoelectric phononic crystal is studiedby considering the mechanic-electric coupling.The gener-alized eigenvalue equation is obtained by the relation of themechanic and electric fields as well as the Bloch-Floquet the-orem.The band structures of both the in-plane and anti-planemodes are calculated for a rectangular lattice by the plane-wave expansion method.The effects of the lattice constantratio and the piezoelectricity with different filling fractionsare analyzed.The results show that the largest gap width isnot always obtained for a square lattice.In some situations,a rectangular lattice may generate larger gaps.The band gapcharacteristics are influenced obviously by the piezoelectric-ity with the larger lattice constant ratios and the filling frac-tions. | Yize Wang Fengming Li Yuesheng Wang Kikuo Kishimoto Wenhu Huang | 2009 | Acta Mechanica Sinica2009，25，1： | 8 |
| 4 | Bifurcation and chaos of the bladed overhang rotor system with squeeze film dampers显示文摘To study the nonlinear dynamic behavior of the bladed overhang rotor system with squeeze film damper (SFD), a blade-overhang rotor-SFD model is formulated using the lumped mass method and the Lagrange approach. The cavitated short bearing model is employed to describe the nonlinear oil force of the SFD. To reduce the scale of the nonlinear coupling system, a set of orthogonal transformations is employed to decouple the one nodal diameter equations of blades, which are coupled with the dy- namical equations of the rotor, with other equations of blades. In this way, the original system with 16+4n (n≥3) degrees of freedom (DoF) is reduced to a system with 24 DoF only. Then the parametric excitation terms in the blade-overhang rotor-SFD model are simplified in terms of periodic transforma- tions. The coupling equations are numerically solved and the solutions are used to analyze the dy- namic behavior of the system in terms of the bifurcation diagram, whirl orbit, Poincaré map and spec- trum plot. A variety of motion types are found such as multi-periodic, quasi-periodic, and chaotic mo- tions. Moreover, the typical nonlinear dynamic evolutions including the periodic-doubling bifurcation and reverse bifurcation are noted. It is noticed that there exist apparent differences in the dynamic behavior between the blade-overhang rotor-SFD models without and with considering the effect of blades. | CAO DengQing WANG LiGang CHEN YuShu HUANG WenHu | 2009 | Science China(Technological Sciences)2009，52，3： | 5 |
| 5 | Maneuver control of the hypersonic gliding vehicle with a scissored pair of control moment gyros显示文摘A maneuver control approach using a scissored pair of control moment gyros is proposed to improve the penetration ability of a hypersonic gliding vehicle(HGV) with a relatively high lift-drag ratio. Then, a multivariable strong coupling nonlinear bank-toturn dynamical model is established for the case of lateral maneuvering of an HGV equipped with a scissored pair of control moment gyros. According to the requirement of coordinated turning of the HGV in a lateral maneuver, a decoupling controller based on feedback linearization and a linear quadratic optimal algorithm is designed. Finally, the large airspace maneuvering trajectories of the HGV including S-shaped, cycloid and spiral maneuvering modes are designed by applying overload control technology. Simulations demonstrate that the designed maneuvering trajectory significantly increases the airspace range and flexibility of the vehicle. The coordinated turn control system achieves an accurate and rapid tracking of the maneuvering trajectories in large airspace. | ZHAO Kun CAO DengQing HUANG WenHu | 2018 | Science China(Technological Sciences)2018，61，8： | 5 |
| 6 | WAVE LOCALIZATION IN RANDOMLY DISORDERED PERIODIC PIEZOELECTRIC RODS WITH INITIAL STRESS显示文摘在有起始的应力的混乱的周期的压电的杆的有弹性的波浪本地化用转移矩阵和 Lyapunov 代表方法被学习。电场作为伪静电干扰被接近。乐队差距特征上的起始的压力的效果被调查。本地化因素和本地化长度的数字计算被执行。它能从结果被观察乐队结构能被施加合适的起始的压力调节。为压电的杆长度和有弹性的常数的不同价值,乐队结构和本地化现象是很不同的。更大的混乱度能导致更多的明显的本地化现象。 | Yize Wang Fengming Li Kikuo Kishimoto Yuesheng Wang Wenhu Huang | 2008 | Acta Mechanica Solida Sinica2008，21，6： | 5 |
| 7 | Modeling and analysis of cantilever beam with active-passive hybrid piezoelectric network显示文摘The active-passive hybrid piezoelectric network (APPN) is investigated to reduce the vibration of cantilever beam. Hamilton's principle with the Rayleigh-Ritz method is used to derive the equations of motion of the beam with the APPN. Only one piezoelectric actuator is bonded on the cantilever beam, so in the segment of the beam where the piezoelectric actuator is attached, the neutral axis is not the geometric center of the beam. This change on the neutral axis is considered in the process of deriving equations. Selecting RL circuit as passive shunt circuit, open-loop analysis is performed to gain insight into the passive damping features. Velocity feedback control is then employed to analyze the characteristics of the closed-loop system. Numerical results show that the APPN has a significant effect on vibration suppression, especially at narrow frequency bands. On this basis, variable RL circuit is proposed and analyzed for broadband vibration attenuation. Numerical simulations illustrate that this scheme is effective and feasible. | LI MingMing FANG Bo CAO DengQing HUANG WenHu | 2013 | Science China(Technological Sciences)2013，56，9： | 4 |
| 8 | Effects of copper mining on heavy metal contamination in a rice agrosystem in the Xiaojiang River Basin, southwest China显示文摘Metallic ore mining causes heavy metal pollution worldwide.However,the fate of heavy metals in agrosystems with long-term contamination has been poorly studied.Dongchuan District(Yunnan,southwest China),located at the middle reaches of the Xiaojiang River,is a well-known 2000-year-old copper mining site.In this work,a survey on soil heavy metal contents was conducted using a handheld X-ray fluorescence instrument to understand the general contamination of heavy metals in the Xiaojiang River Basin.Furthermore,river water,soil,and rice samples at six sites along the fluvial/alluvial fans of the river were collected and analyzed to implement an environmental assessment and an evaluation of irrigated agrosystem.V,Zn,and Cu soil levels(1724,1047,and 696mg·kg-1,respectively)far exceeded background levels.The geo-accumulation indexes(Igeo)showed that cultivated soils near the mining sites were polluted by Cd and Cu,followed by Zn,V,Pb,Cr,Ni,and U.The pollution index(Pi)indicated that rice in the area was heavily polluted with Pb,Cr,Cd,Ni,Zn,and Cu.The difference in orders of metal concentrations between the soil and rice heavy metal contamination was related to the proportion of bioavailable heavy metals in the soil.The crop consumption risk assessment showed that the hazard quotient exceeded the safe threshold,indicating a potential carcinogenic risk to consumers.The Nemerow integrated pollution index and health index indicated that the middle of the river(near the mining area)was the heaviest polluted site. | Wanqiu Pu Jiaqi Sun Fangfang Zhang Xingyue Wen Wenhu Liu Chengmin Huang | 2019 | Acta Geochimica2019，38，5： | 4 |

| 11 | Vibration control of the finite L-shaped beam structures based on the active and reactive power flow显示文摘This paper analyzes the physical meaning of the active and reactive power flow in the finite L-shaped beams and studies the active vibration control of the structures based on the active and reactive power flow.The traveling wave approach is used to calculate the structural dynamic responses.Because the error of control force is inevitable in practical applications,the effects of the error of control force on the control results are studied.The study indicates that the error of control force has pronounced influence on the control results of the acceleration and reactive power flow.It is obvious that the reactive power flow can represent the vibration strength component of the complex intensity,and the active power flow strongly depends on the structural damping of the finite beams. | LIU ChunChuan LI FengMing TANG Liang HUANG WenHu | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，2： | 2 |

| 13 | Preparation and characterization of some surface negatively charged residue mutants of cytochrome b_5显示文摘Site-directed mutagenesis was used to obtain seven variants of tryptic fragment of bovine liver cytochrome bs (cyt bs), in which the negatively charged residues around the heme exposed edge of cyt bs were replaced by hydropho-bic amino acid alanine. Double-site mutants, triple-site mutants and even quadruple-site mutants were obtained. DNA sequencing and molecular weight measurements of the mutant proteins both confirmed that these site-directed muta-genesises were successfully performed. Spectroelectrochem-istry of these mutant proteins revealed that the apparent redox potentials of these mutant proteins caused a positive shift of 2-10 mV. The global structure of these mutant proteins did not show much difference from that of the wild type cyt bs, providing a solid base for the further study on the roles of the proteins’ surface charges. | WANG Yunhua, WANG Wenhu, LU Junxia, REN Yi, GU Shaohua, XIE Yi & HUANG Zhongxian1.

| 14 | NORMAL MODES OF FLUID-STRUCTURE INTERACTION IN INTERNAL FLOWS显示文摘As an important cornerstone, the methodology of normal modal analysis plays a quite important role in dynamic analyses of linear vibrating systems, and makes much easy to access an understanding of frequency-domain characteristics of the systems. However, most reported work on fluid-structure interaction (FSI) in liquid-filled pipes has been directly carried out in the time domain. When needed, information in the frequency domain has been deduced by the discrete Fourier transforms. In this paper, an analysis is undertaken directly to get modal information of FSI in internal flows and has the advantage of enabling dispersive and dissipative terms to be included in a fully coupled manner.The development used herein highlights common features of the analysis in the frequency domain. The method is validated by comparison with an exact analytical solution, with the results obtained by the discrete Fourier transform from an analysis using the method of characteristics and by comparison with measured data | Zhang, Lixiang Huang, Wenhu Tijsseling, Arris S.
