摘　　要：以某静液驱动高速履带车辆为研究对象,通过引入爬坡裕度系数和速度裕度系数表征静液驱动履带车辆爬坡、最大车速等直驶工作能力。系数大小体现了系统克服动态冲击和工况适应能力的强弱,适宜的系数设置可以指导履带车辆静液驱动系统的设计。研究表明:在良好路面(如沙石土路)上爬坡裕度系数取值不小于1.07,速度裕度系数取值为1.67～1.88时可以基本满足车辆的直驶需求。Taking a certain hydrostatic drive track vehicle as the research objective,2 parameters,the climbing margin coefficient and the speed margin coefficient were introduced to characterize its straight driving capability at climbing and maximum speed conditions.The magnitude of the coefficient reflects the capability of the vehicle to overcome the dynamic impact and adapt to different working conditions.The suitable set of coefficients can direct the design of the track vehicle hydrostatic drive system.The research results showed that the straight driving demand of the vehicle was satisfied essentially at the climbing margin coefficient no less than 1.07 and the speed margin coefficient 1.67~1.88.
