Research of Impact Load in Large Electrohydraulic Load Simulator

Abstract EN

The stronger impact load will appear in the initial phase when the large electric cylinder is tested in the hardware-in-loop simulation.

In this paper, the mathematical model is built based on AMESim, and then the reason of the impact load is investigated through analyzing the changing tendency of parameters in the simulation results.

The inhibition methods of impact load are presented according to the structural invariability principle and applied to the actual system.

The final experimental result indicates that the impact load is inhibited, which provides a good experimental condition for the electric cylinder and promotes the study of large load simulator.
