Abstract
Single hydraulic system modelling leads to distorted predictions of system dynamic characteristics due to simplification of flow field in main control valve.Taking electro-hydraulic shift control system as object,a real-time co-simulation method for coupling transient flow field of main control valve with dynamic simulation of hydraulic system is proposed and realized,the synchronous operation data of electro-hydraulic control system model and its main control valve flow field model are communicated in real time through TCP/IP interface.The results show that this method can accurately capture the internal transient flow field parameters and transient flow force during the regulating process of the main control valve,and then give high precision parameters of the main control valve in the hydraulic system model in real time,reproducing system vibration and spool self-excited vibration.At the same time,it is found that the steady state value of the main control valve flow force is 12.53 N by real-time co-simulation of the system,while the value of the system simulation is only 0.50 N,which is greatly different from the traditional theoretical calculation value of 8.09 N.This difference is one of the main reasons for the difference in dynamic performance prediction.关键词
