摘　　要：以某轻型客车制动踏板为研究对象,通过人体下肢受力分析及竞品车对标分析,发现该车制动踏板操作舒适性差的主要原因为踝角角度过小。通过对踏板垫支架弧度、焊接角度及踏板垫形状的调整,完成了踏板的改进设计;将改进后的制动踏板进行人机校核、有限元分析、台架试验及主观评价,制动踏板在满足设计要求的同时,操作舒适性得到了提升。In this article,with the focus on the light bus’ brake pedal,the force analysis is conducted on the lower limbs and the benchmarking analysis is carried out on the competitive vehicle. Thus,poor operating comfort is mainly caused by minor angle of the ankle. Through the modification of the pad bracket’s radian,the welding angle and the pad shape,the brake pedal has improved in design. Such tasks as ergonomics check,finite-element analysis,bench test and subjective evaluation are performed on the new brake pedal. While meeting the design requirements,the brake pedal has a higher standard of operating comfort.
