摘　　要：本文描述了复杂的大功率液压系统数字仿真中容易出现的刚性问题，讨论迭代技术在解决此问题的仿真方法，并用该方法对一台３０ＭＮ水压机液压系统的加压过程进行了仿真计算。计算结果表明：迭代法能大大提高仿真计算的效率，是复杂的大功率液压系统仿真计算的一种行之有效的方法。最后。This paper describes a stiff problem encountered in the digital simulation of complex high power hydrulic system and discusses a method using iterative technique to solve it. Using the method,the press process of a 30MN press hydraulic system has been simulated. The results of simulation calculation show that the iterative method can greatly raise the efficiency of simulation,and it is an effective method of simulation of hydraulic system. At last,some characteristic about 3 stage cartridge values of press hydraulic system is discussed.
