摘　　要：本文通过对滑转率计算公式的简化,并对液压驱动系统的效率、压力、速度进行了分析,建立了能反映其整体性能的牵引性能方程,最后对其进行了台架试验和样机牵引试验验证,为推土机整机性能的研究和推土机控制系统的设计提供了依据,这对于其它静液压驱动机型也有一定参考意义。Through the simplification of formula to calculate tract slip ratio, a tra ction equation reflecting overall machine performance is set up after the analysis of the efficiency, pressure and velocity in hydraulic drive systems. Test verificat ion were conducted by bench test and prototype traction test. All these provides a basis for the study of overall dozer performance and its design of control sy stems as well as a reference for other hydrostatic drive machines.
