摘要：
The wet clutch is the core component of the vehicle transmission system. It is prone to rub-im-pact between the friction plate and steel plate during high-speed separation,resulting in a sharp increase in drag torque,and affecting its transmission efficiency and reliability. Therefore,in this paper,to reduce the rub-impact drag torque in high-speed wet clutch,the micro-texture on the surface of the friction plate is optimally designed. Firstly,a parameterized modeling method of arbitrary micro-texture shape lines on the surface of friction plate is pro-posed. Then the number,depth,circumferential proportion,radial proportion and shape line parameters of the mi-cro-texture are selected to construct the design variables,constraint conditions and optimal objective function for mi-cro-texture optimization. By combining the experiment design method,approximation modeling simulation and glob-al search optimization method,an optimal design model of micro-texture on the surface of friction plate is estab-lished. Finally,a comparison test of drag torque before and after micro-texture optimization is carried out. The re-sults show that the optimized micro-texture can significantly reduce the rub-impact drag torque at high circumferen-tial speed,and greatly delay the critical speed at which the rub-impact phenomenon of friction pair occurs. © 2024 SAE-China.
