Simulation analysis of loading curve for clutch integral waveform piece based on Abaqus

Abstract

Taking a certain type of 65Mn clutch integral waveform piece as the research object, numerical simulation analysis was carried out on the deformation process of waveform piece by Abaqus finite element analysis software, and the axial compression characteristic curve (loading curve) generated by the force exerted on waveform piece by the friction plate was predicted. The influence of thickness, forming height and fillet radius of waveform piece on pressure-displacement curve was studied, and the simulation results were compared with the product requirements. The results show that the inflection point of the loading curve can be shifted to the right with small thickness and large forming height, which shows that the actual load interval of the waveform piece decreases, and the deformation of the waveform piece can be caused by the smaller pressure. While the influence of the fillet radius value on the loading curve is not obvious. The loading experiment of the waveform piece with given parameters was carried out, the experimental results are basically consistent with the numerical curves of the simulation analysis, indicating that the Abaqus simulation analysis can provide references for the performance matching optimization of the waveform piece.
