坐姿人体四自由度动力学模型研究 —— 集中参数模型及其在汽车乘坐舒适性研究中的应用
Research on 4-degree-of-freedom dynamics model of seated human :lumped-parameter model and its application to ride comfort research for automobiles
摘要
Abstract
It is of significance to study the dynamic model of the seated human body ,for possibly improving the research and development of dynamics response efficiency of the applications sys -tems of the seated human body .A 4-degree-of-freedom (4DOF ) lumped-parameter model was proposed ,and the model parameters were identified by utilizing a multi-object function coordina-ted optimization-based principle .The proposed model was also compared and analyzed with other classical 4DOF lumped-parameter models .A "human-seat-automobile" 7DOF model was further established based on the proposed model .The simulation experiment of the dynamics responses of the seated human body ,when the automobile on different road conditions ,was conducted ,and the root mean square acceleration was used to quantitatively analyze and evaluate the dynamics re -sponses of the seated human .The research results showed that , the non-dominated sorting genetic algorithm- Ⅱ (NSGA- Ⅱ ) worked effectively for coordinately optimizing the multi objec-tives of the 4DOF lumped-parameter models .Further ,the proposed model can describe the dy-namic responses for seated human body more effectively ,also can be applied to the research work on riding comfort (driving comfort) of vehicles .关键词
