The research prototype of the novel system, which features a distinctive overrunning clutch drive, is presented. Through co-simulation with ANSYS, MATLAB, and SOLIDWORKS software, a comprehensive multi-objective optimization is performed to enhance the dynamics performance of the prototype. Firstly, the wearing contact stiffness of the prototype and the mechanical parameters of the relevant materials are simulated and fitted based on the principle of functional equivalence. And then, its equivalent nonlinear circumferential stiffness model is obtained. Secondly, to enhance the wearing comfort of the exoskeleton, a novel comprehensive performance evaluation index, termed wearing comfort, is introduced. The index considers multiple factors such as the duration of vibration transition, the acceleration encountered during wear, and the average pressure applied. Finally, through the utilization of this indicator, the system\u2019s dynamics performance is optimized via multi-platform co-simulation, and the simulation results validate the effectiveness of the research method and the proposed wearable comfort index. The theoretical basis for the subsequent research on the effectiveness of prototype weight-bearing is provided.<\/jats:p>","DOI":"10.1017\/s0263574724001723","type":"journal-article","created":{"date-parts":[[2024,10,31]],"date-time":"2024-10-31T11:15:48Z","timestamp":1730373348000},"page":"3918-3933","source":"Crossref","is-referenced-by-count":4,"title":["Optimization and synthesis on the dynamics performance of the tensioning and relaxing wearable system in a novel knee exoskeleton using co-simulation"],"prefix":"10.1017","volume":"42","author":[{"given":"Yuwei","family":"Yang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-0910-5634","authenticated-orcid":false,"given":"Jiapeng","family":"Yin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenyao","family":"Qi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhaotong","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zuyi","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhongyu","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jinyou","family":"Xu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2024,10,31]]},"reference":[{"key":"S0263574724001723_ref10","doi-asserted-by":"publisher","DOI":"10.1017\/S0263574723001030"},{"key":"S0263574724001723_ref14","doi-asserted-by":"publisher","DOI":"10.1109\/TMECH.2018.2872011"},{"key":"S0263574724001723_ref2","doi-asserted-by":"publisher","DOI":"10.3390\/bioengineering11020110"},{"key":"S0263574724001723_ref15","doi-asserted-by":"publisher","DOI":"10.1179\/2045772313Y.0000000126"},{"key":"S0263574724001723_ref24","doi-asserted-by":"publisher","DOI":"10.1353\/chn.2015.0032"},{"key":"S0263574724001723_ref12","first-page":"6","article-title":"MATLAB-based oscillatory phase simulation of lower limb prostheses","volume":"40","author":"Gong","year":"2011","journal-title":"J Hebei Univ Technol"},{"key":"S0263574724001723_ref23","first-page":"1","article-title":"An adaptive variable stiffness extracorporeal knee joint device with intelligent tensioning function","author":"Yang","year":"2020","journal-title":"China"},{"key":"S0263574724001723_ref31","doi-asserted-by":"publisher","DOI":"10.1017\/S0263574721001740"},{"key":"S0263574724001723_ref33","first-page":"591","article-title":"Multi-objective optimization design of coal mining machine spiral drum based on genetic algorithm","volume":"29","author":"Zhao","year":"2018","journal-title":"China Mech Eng"},{"key":"S0263574724001723_ref25","doi-asserted-by":"publisher","DOI":"10.1249\/MSS.0b013e318199885c"},{"key":"S0263574724001723_ref21","first-page":"877","article-title":"Joint simulation of vehicle cornering brake ABS based on ADAMS and simulink","volume":"20","author":"Xu","year":"2009","journal-title":"China Mech Eng"},{"key":"S0263574724001723_ref26","first-page":"166","article-title":"Research progress of unpowered exoskeleton assist robot","volume":"44","author":"Shen","year":"2020","journal-title":"J Mech Transm"},{"key":"S0263574724001723_ref16","first-page":"23","volume-title":"Wearable Robots: Biomechatronic Exoskeletons","author":"Jose","year":"2008"},{"key":"S0263574724001723_ref32","doi-asserted-by":"publisher","DOI":"10.1115\/1.1537269"},{"key":"S0263574724001723_ref17","doi-asserted-by":"publisher","DOI":"10.1682\/JRRD.1985.07.0007"},{"key":"S0263574724001723_ref34","unstructured":"[34] General Administration of Quality Supervision, Inspection and Quarantine of the People\u2019s Republic of China, Mechanical Vibration and Shock -
