Study of Equivalent Thrust and Multistage Hydraulic Cylinders Based on Joint Simulation

对多级等推力液压缸的原理进行说明,并采用基于ADAMS与Matlab/Simulink联合仿真方案对其进行仿真,通过把建好的虚拟样机导入到ADAMS建立动力学模型,同时针对多级等推力液压缸内部容腔进行数学建模,从而模拟出内部的液压流动,并利用Matlab/Simulink根据数学模型建立起液压模型,通过ADAMS与Matlab的接口对多级等推力液压缸进行联合仿真.

The principle of equivalent thrust and multistage hydraulic cylinder are explained and simulated by using joint simulation based on ADAMS and Matlab/Simulink. The dynamic model is constructed by importing the established virtual prototype to ADAMS. Meanwhile, the mathematical modeling of the chamber of equiva- lent thrust and multistage hydraulic cylinder is conducted, and the inner hydraulic flow is simulated. Through Matlab/Simulink, the hydraulic model is established based on mathematical model. Through the interface of ADAMS and Matlab/Simulink the joint simulation of equivalent thrust and multistage hydraulic cylinder is car- ried out.
