摘　　要：在手动挡汽车中,离合器踏板属于车辆的操纵机构,其设计合理与否,直接关系到车辆的操控性、舒适性和安全性。从某新开发轿车在实车试验过程中出现的实际问题出发,利用踏板臂数据和人体模型详细分析了离合器踏板臂与脚尖干涉问题出现的原因,通过脚尖移动包络优化设计踏板臂边界,并对优化后的踏板臂进行了CAE强度刚度分析和试验验证。In the sedan with manual transmission, the clutch pedal belongs to the control mechanism of the vehicle. The rationality of its design is directly related to the handling, comfort and safety. Based on the actual problem of a newly developed car in the process of test, the cause of the interference between clutch pedal arm and tiptoe is analyzed by using pedal data and human model, the pedal arm boundary is then optimized through tiptoe moving envelope. The strength and rigidity of the optimized pedal arm are analyzed by CAE software and verified in testing vehicles as well.
