摘　　要：基于地面力学理论和液压传动理论,对采用不同同步方式的单泵多马达液压行走系统的动力学问题进行了研究。建立了行走系统的动力学模型,对比了行走系统的牵引力、速度和传动效率。结果表明:在单泵多马达液压行走系统同步方式中,电子防滑技术的性能优于同步分流和自有分流技术。Terrain mechanics and hydraulic transmission theory were used in studying the dynamics of running system which is driven by single-pump and multi-motor with different synchrony technologies. Dynamics models for running system were established; traction force, velocity and driving efficiency were compared. The results indicate that electronic anti-slip technology is better than synchronous distribution and free distribution.
