Abstract:

A method to dynamically simulate a hydraulic system based on the software SIMULINK is presented. The characteristic of software SIMULINK is introduced and the dynamical model of valve controlled hydraulic cylinder is constructed. The simulation model is established and the method to simulate the dynamical characteristics of the hydraulic system is introduced in detail. The dynamical simulation of hydraulic system can be made by establishing the dynamical model and the simulation model of hydraulic system, initializing the parameters of the system, and implementing the dynamical simulation. Meanwhile the key factors affecting the dynamical characteristics of hydraulic system are discussed. The simulation results show that the SIMULINK method is an effective way to simulate the dynamical characteristics of the hydraulic system.
