摘　　要：出口节流调速系统是液压节流调速系统的一部分,通常是采用传递函数法建立系统数学模型对其进行动态特性分析,这种方法不但复杂,而且效果不佳。文中提出的采用功率键合图法建立系统数学模型,利用MATLAB软件进行快速而准确的数字仿真,并分析系统参数对其性能的影响,对研究系统的性能和设计改进具有积极的意义。The out throttle governing circuits is the important part of hydraulic throttle governing circuits. It often uses traditional function for establishing mathematical model. It is not only complex but also inefficient. This paper uses power bond graphs for establishing the mathematical model and uses MATLAB for quick and precise digital simulation. And the effects on systemic parameters to its performance are analyzed. So it is important to study the characteristic and improve design of the system.
