摘　　要：液压控制系统往往是欠阻尼的,液压阻尼比小直接影响到系统的稳定性。本文作者对泵控装置采用动压反馈装置,提高了系统的稳定性,同时满足静态特性和动态特性两方面的要求;对驱动系统加入蓄能器环节,提高了系统的行驶稳定性和功率利用率。Hydraulic control system is often less damping, small hydraulic damping ratio would impact on the stability of system directly. Dynamic pressure feedback device was used for the pump control device, which improves the stability of system, meets the request of both static and dynamic characteristics, to use accumulator in the driving system with the accumulator, the stability of trafficing and the utilization of power were improved.

关 键 词：静液驱动 液压阻尼比 动压反馈
