摘　　要：变量泵排量控制流量通道的控制阻尼孔决定变量泵排量控制伺服阀的流量增益的大小,影响转向泵排量控制响应特性和静液驱动调速系统的响应品质。本文通过试验和仿真两个方面,分析了排量控制阻尼孔对排量控制机构响应特性的影响。Zero differential power-split hydrostatic transmission is a drive box for advanced armored tracked vehicular, which combines hydrostatic steering mechanism and.mechanical power-shift mechanism. The core of steering mechanism is a hydrostatic unit with a variable displacement pump and fixed displacement motor. Modeling accurately the hydrostatic unit is the key of simulation of stepless steering performance of vehicle. The dynamic analysis of displacement control mechanism of variable pump affected by control orifice was given. A simplified mathematical model and simulator was derived on the basis of physical consideration.
