9Solving open vehicle problem with time window by hybrid column generation algorithm显示文摘This paper addresses the open vehicle routing problem with time window(OVRPTW), where each vehicle does not need to return to the depot after completing the delivery task.The optimization objective is to minimize the total distance. This problem exists widely in real-life logistics distribution process.We propose a hybrid column generation algorithm(HCGA) for the OVRPTW, embedding both exact algorithm and metaheuristic. In HCGA, a label setting algorithm and an intelligent algorithm are designed to select columns from small and large subproblems, respectively. Moreover, a branch strategy is devised to generate the final feasible solution for the OVRPTW. The computational results show that the proposed algorithm has faster speed and can obtain the approximate optimal solution of the problem with 100 customers in a reasonable time.YU Naikang QIAN Bin HU Rong CHEN Yuwang WANG Ling 2022Journal of Systems Engineering and Electronics2022,33,4:0
10Design and experiment of a novel pneumatic soft arm based on a deployable origami exoskeleton显示文摘T Soft arms have shown great application potential because of their flexibility and compliance in unstructured environments.However,soft arms made from soft materials exhibit limited cargo-loading capacity,which restricts their ability to manipulate objects.In this research,a novel soft arm was developed by coupling a rigid origami exoskeleton with soft airbags.The joint module of the soft arm was composed of a deployable origami exoskeleton and three soft airbags.The motion and load performance of the soft arm of the eight-joint module was tested.The developed soft arm withstood at least 5 kg of load during extension,contraction,and bending motions;exhibited bistable characteristics in both fully contracted and fully extended states;and achieved a bending angle of more than 240°and a contraction ratio of more than 300%.In addition,the high extension,contraction,bending,and torsional stiffnesses of the soft arm were experimentally demonstrated.A kinematic-based trajectory planning of the soft arm was performed to evaluate its error in repetitive motion.This work will provide new design ideas and methods for flexible manipulation applications of soft arms.Yuwang LIU Wenping SHI Peng CHEN Yi YU Dongyang ZHANG Dongqi WANG 2023Frontiers of Mechanical Engineering2023,18,4:0
11Design and Analysis of a 2-DOF Actuator with Variable Stiffness Based on Leaf Springs显示文摘Variable Stiffness Actuator(VSA)is the core mechanism to achieve physical human–robot interaction,which is an inevitable development trend in robotic.The existing variable stiffness actuators are basically single degree-of-freedom(DOF)rotating joints,which are achieving multi-DOF motion by cascades and resulting in complex robot body structures.In this paper,an integrated 2-DOF actuator with variable stiffness is proposed,which could be used for bionic wrist joints or shoulder joints.The 2-DOF motion is coupling in one universal joint,which is different from the way of single DOF actuators cascade.Based on the 2-DOF orthogonal motion generated by the spherical wrist parallel mechanism,the stiffness could be adjusted by varying the effective length of the springs,which is uniformly distributed in the variable stiffness unit.The variable stiffness principle,the model design,and theoretical analysis of the VSA are discussed in this work.The independence of adjusting the equilibrium position and stiffness of the actuator is validated by experiments.The results show that the measured actuator characteristics are sufficiently matched the theoretical values.In the future,VSA could be used in biped robot or robotic arm,ensuring the safety of human–robot interaction.ShangKui Yang Peng Chen DongQi Wang Yi Yu YuWang Liu 2022Journal of Bionic Engineering2022,19,5:0
12Variable Curvature Modeling Method of Soft Continuum Robots with Constraints显示文摘The inherent compliance of continuum robots holds great promise in the fields of soft manipulation and safe human–robot interaction.This compliance reduces the risk of damage to the manipulated object and its surroundings.However,continuum robots possess theoretically infinite degrees of freedom,and this high flexibility usually leads to complex deformations when subjected to external forces and positional constraints.Describing these complex deformations is the main challenge in modeling continuum robots.In this study,we investigated a novel variable curvature modeling method for continuum robots,considering external forces and positional constraints.The robot configuration curve is described using the developed mechanical model,and then the robot is fitted to the curve.A ten-section continuum robot prototype with a length of 1 m was developed in order to validate the model.The feasibility and accuracy of the model were verified by the ability of the robot to reach target points and track complex trajectories with a load.This work was able to serve as a new perspective for the design analysis and motion control of continuum robots.Yuwang Liu Wenping Shi Peng Chen Liang Cheng Qing Ding Zhaoyan Deng 2023Chinese Journal of Mechanical Engineering2023,36,6:0
13Design and modeling of a novel soft parallel robot driven by endoskeleton pneumatic artificial muscles显示文摘Owing to their inherent great flexibility, good compliance, excellent adaptability, and safe interactivity, soft robots have shown great application potential. The advantages of light weight, high efficiency, non-polluting characteristic, and environmental adaptability provide pneumatic soft robots an important position in the field of soft robots. In this paper, a soft robot with 10 soft modules, comprising three uniformly distributed endoskeleton pneumatic artificial muscles, was developed. The robot can achieve flexible motion in 3D space. A novel kinematic modeling method for variable-curvature soft robots based on the minimum energy method was investigated, which can accurately and efficiently analyze forward and inverse kinematics. Experiments show that the robot can be controlled to move to the desired position based on the proposed model. The prototype and modeling method can provide a new perspective for soft robot design, modeling, and control.Peng CHEN Tingwen YUAN Yi YU Yuwang LIU 2022Frontiers of Mechanical Engineering2022,17,2:0
14High-performance terahertz modulators induced by substrate field in Te-based all-2D heterojunctions显示文摘High-performance active terahertz modulators as the indispensable core components are of great importance for the next generation communication technology.However,they currently suffer from the tradeoff between modulation depth and speed.Here,we introduce two-dimensional(2D)tellurium(Te)nanofilms with the unique structure as a new class of optically controlled terahertz modulators and demonstrate their integrated heterojunctions can successfully improve the device performances to the optimal and applicable levels among the existing all-2D broadband modulators.Further photoresponse measurements confirm the significant impact of the stacking order.We first clarify the direction of the substrate-induced electric field through first-principles calculations and uncover the unusual interaction mechanism in the photoexcited carrier dynamics associated with the charge transfer and interlayer exciton recombination.This advances the fundamental and applicative research of Te nanomaterials in high-performance terahertz optoelectronics.Pujing Zhang Qihang Liang Qingli Zhou Jinyu Chen Menglei Li Yuwang Deng Wanlin Liang Liangliang Zhang Qinghua Zhang Lin Gu Chen Ge Kui-juan Jin Cunlin Zhang Guozhen Yang 2024Light(Science & Applications)2024,13,3:0
