Theoretical Stiffness Modeling and Application Research of a Novel Stacked Flexure Hinge by Yonghong Zhang, Chengmin Wang, Shuangquan Tang, You Jiang, Hong Chen, Wenjie Ge

“…This study investigates and designs a novel stacked hinge with low stiffness, large rotation angle, high strength, and length-adaptive functionality. Firstly, based on the large deformation theory of cantilever beams and relevant theories of leaf springs, a stiffness theoretical model for stacked flexure hinges is established. …”

A particle swarm optimization algorithm with empirical balance strategy by Yonghong Zhang, Xiangyu Kong

“…In this article, based on empirical balance strategy, a new particle swarm optimization (EBPSO) algorithm is presented. Firstly, based on an adaptive adjustment mechanism, the algorithm can choose a better strategy from two search equations, which can maintain the balance between the exploration and exploitation abilities. …”

Lumbar spine localisation method based on feature fusion by Yonghong Zhang, Ning Hu, Zhuofu Li, Xuquan Ji, Shanshan Liu, Youyang Sha, Xiongkang Song, Jian Zhang, Lei Hu, Weishi Li

“…Abstract To eliminate unnecessary background information, such as soft tissues in original CT images and the adverse impact of the similarity of adjacent spines on lumbar image segmentation and surgical path planning, a two‐stage approach for localising lumbar segments is proposed. First, based on the multi‐scale feature fusion technology, a non‐linear regression method is used to achieve accurate localisation of the overall spatial region of the lumbar spine, effectively eliminating useless background information, such as soft tissues. …”

Optimization Design and Performance Analysis of a Bionic Knee Joint Based on the Geared Five-Bar Mechanism by Zhuo Wang, Wenjie Ge, Yonghong Zhang, Bo Liu, Bin Liu, Shikai Jin, Yuzhu Li

“…In this paper, by imitating the knee joint of a kangaroo, we propose a new bionic geared five-bar knee joint mechanism to improve the energy utilization rate of the legged robot and reduce the required driving power. Firstly, based on image processing technology, the trajectory curve of the instantaneous center of rotation (ICR) of the kangaroo knee joint was quickly obtained. …”
