摘　　要：根据履带式车辆的运动特点,运用数力学理论,分别对履带式车辆在纵向和横向坡道上的匀速转向特性进行了分析,并在此基础上着重研究了地面纵向坡度、横向坡度对履带式车辆匀速转向的影响,即重力的纵向分力、横向分力对匀速转向的影响,研究在这些外力作用下,履带式车辆的转向运动规律,从而得出履带式车辆转向的最困难条件,为进行转向牵引计算和转向机构强度设计提供根据。According to the moving characteristics of tracked vehicles,using several mechanics theory,the steering characteristics of tracked vehicles on longitudinal and transverse ramps are respectively analyzed,and based on this study,the influences of longitudinal and transverse ramp on uniform steering for tracked vehicles are particularly studied,that＇s to say,influences of gravity＇s longitudinal and transverse force on uniform steering.The steering movement rules of tracked vehicles are obtained under the condition of these outside forces,then the most difficult condition during tracked vehicle steering are also obtained,and which can provide a foundation for steering calculation and strength design of steering mechanism.
