Structure of an ultrahigh internal pressure compound cylinder and its simulation by AMESim

This study presents an ultrahigh internal pressure compound booster cylinder and analyses the structure and principle of the cylinder. Its advantages include low input, high pressure output, and direct action on the execution cylinder. The model of the ultrahigh internal pressure compound booster cylinder is constructed by AMESim, and the result is analysed. By analysing the research and simulation results for this cylinder, the authors eventually designed an integrated composite hydraulic cylinder assembly that can realise the large pressure output of fast-forward and quick return actions.
