中文摘要：

基于生物力学分析,研究了踏板设计参数对踏板操作时下肢肌肉疲劳的影响。定义了4个设计因子：座椅高度、踏板行程、踏板行程倾角和踏板高度,进行中心复合试验设计。应用生物力学软件Any Body对25组试验进行了仿真分析,通过对仿真结果的回归分析得出各设计因子的影响权重,并分析了每个因子对不同百分位人体最大肌肉活动度的影响,给出设计因子的推荐取值范围。该方法建立了踏板的工程设计与驾驶员踏板操作舒适性的联系,为汽车踏板的人机工程参数化设计提供依据。

英文摘要：

Based on biomechanical analysis, the influences of pedal design parameters on the leg muscle fatigue of driver in operating pedal are studied. Four design factors, i.e. seat height, pedal travel, pedal travel an- gle and pedal height are defined and a central composite experimental design is conducted. Then 25 groups of exper- iments are simulated with biomechanical software AnyBody, the weighing coefficients for each design factor are ob- tained by regression analysis on simulation results, and the effects of each factor on the maximum muscle activity for human bodies of different percentiles are analyzed with the recommended range of design factor given. This method establishes the correlations between pedal engineering design and driver＇s comfort in pedal operation, providing a ba- sis for the ergonomic parametric design of vehicle pedal.
