摘　　要：针对某车型手刹在开发阶段测试时发现坡道驻车时手刹在多次拉动后行程增加进而可能会导致安全事故的问题进行研究。通过利用Abaqus在不同工况下进行刚度分析来寻找影响手刹行程增加的关键项,得到了不同因素的行程增加量,然后对影响行程增加的关键量进行分析,选择对手刹机构进行优化。对手刹机构进行了强度分析,分析结果表明转轴的刚度严重影响汽车手刹行程,通过更改转轴刚度材料,大大缩短了该车型的手刹行程。整个分析优化过程为以后的同类车型的开发积累了经验。For a MPV car, the handbrake stroke increased in the test phase ramp R&D after several pulling in turn and that may lead to problems of security incidents. To solve this problem, influencing factors are found by using Abaqus. Amount of travel by different factors are calculated. Then handbrake mechanism is optimized. Strength analysis of handbrake mechanism is conducted, and the results show that the stroke of the shaft stiffness severely affect the car handbrake stroke. So, changing the stiffness of the shaft material can greatly reduce the car's hand brake stroke. These workes are important for the future de-velopment of similar cars.
