| 1 | Optimal Design for an End Face Engagement Worm Gear with Multiple Worm-wheel Meshing显示文摘To solve the problem for lacking a special mechanical transmission that could provide multiple outputs with high transmission efficiency and good lubrication in the modern industrial, a novel worm gear, named end face engagement worm gear, with multiple worm-wheel meshing is proposed for the first time. The essential parameters for the worm gear are optimized to enhance lubrication and meshing properties. Moreover, analysis of variance(ANOVA) is applied to determine the optimum levels and to determine the influence of parameters. The ANOVA results show that the novel end face engagement worm gear with multiple worm wheels provides high lubrication(the lubrication angle is more than 89°) and meshing performance(the induce normal curvature is less than 0.0002 mm^(-1)). The interaction between center distance and roller slant distance most strongly influences the lubrication angle(contributed 51.6%), followed by the parameters of center distance(contributed 25.0%), roller slant distance(contributed 16.4%), tooth angle of gear, gear ratio, and roller radius. In addition, roller radius most strongly influences the induced normal curvature(contributed 39.4%), followed by roller slant distance(contributed 15.2%), tooth angle of the gear(contributed 9.0%), center distance, and gear ratio. The proposed worm gear helps to enrich the no-backlash high precision worm drive and the optimal design method can provide a useful reference on performance improvement of other worm gear. | DENG Xingqiao ZHU Weibing CHEN Yonghong CHEN Shouan WANG Jinge | 2017 | Chinese Journal of Mechanical Engineering2017，30，1： | 9 |
| 2 | English and Chinese language frequency time series analysis显示文摘English and Chinese language frequency time series (LFTS) were constructed based on an English and two Chinese novels. Methods of statistical hypothesis testing were adopted to test the nonlinear properties of the LFTS. Results suggest the series exhibited non-normal, auto-correlative, and stationary characteristics. Moreover, we found that LFTS follow the power law distributions, and thereby we investigated the fractal structure, long range correlation, and intermittency, which indicated the self-similarity features of LFTS, and also provided hints that human societies are likely to share some universal properties. | DENG WeiBing WANG DuJuan LI Wei WANG Qiuping Alexandre | 2011 | Chinese Science Bulletin2011，56，34： | 3 |

| 10 | A Well-Conditioned, Nonconforming Nitsche’s Extended Finite Element Method for Elliptic Interface Problems显示文摘In this paper,we introduce a nonconforming Nitsche’s extended finite element method(NXFEM)for elliptic interface problems on unfitted triangulation elements.The solution on each side of the interface is separately expanded in the standard nonconforming piecewise linear polynomials with the edge averages as degrees of freedom.The jump conditions on the interface and the discontinuities on the cut edges(the segment of edges cut by the interface)are weakly enforced by the Nitsche’s approach.In the method,the harmonic weighted fluxes are used and the extra stabilization terms on the interface edges and cut edges are added to guarantee the stability and the well conditioning.We prove that the convergence order of the errors in energy and L 2 norms are optimal.Moreover,the errors are independent of the position of the interface relative to the mesh and the ratio of the discontinuous coefficients.Furthermore,we prove that the condition number of the system matrix is independent of the interface position.Numerical examples are given to confirm the theoretical results. | Xiaoxiao He Fei Song Weibing Deng | 2020 | Numerical Mathematics(Theory,Methods and Applications)2020，13，1： | 1 |
