Parameter Optimization And Simulation Of Dry Dual Clutch Friction Plate

With the rapid development of the automotive industry,consumers are more inclined to purchase motor vehicles with superior comfort and high performance.As the core linkage mechanism of a motor vehicle,the transmission system plays an important role in comfort and transmission efficiency.Due to its simple structure,high transmission efficiency,fast start,and soft shifting,the dry double clutch has attracted widespread attention.However,due to the lack of a cooling system,the thermal capacity limit is relatively low,and the friction plate is easily ablated under high power input.In this paper,taking a certain car as the research object,the parameters of its dry double clutch friction plate are optimized.In this paper,the optimization goal is to reduce the surface heat flow density of the dry double clutch friction plate in the working state,so as to achieve the purpose of reducing the maximum temperature reached in the working state.Using MATLAB gray wolf optimization algorithm,an optimized design scheme for the friction plate is proposed.Set its working conditions as constraints.After optimization,the heat flux density on the surface of the friction plate was reduced by 14.03%.The optimization is ideal and consistent with the actual working conditions.Using modern design theory and methods,the theoretical system is divided into three steps:optimal design,three-dimensional modeling,and finite element analysis.So as to achieve optimization results through simulation.First,the model was built using SolidWorks and imported into ANSYS for finite element analysis.Thus,the peak temperature of the clutch during single start and continuous start is obtained before and after optimization.The results show that the temperature of the single start of the optimized friction plate is reduced by 23.28%compared with that before the optimization;the maximum temperature of the ten consecutive starts after optimization is 83.485℃,which meets the material temperature requirements,which proves the feasibility of the optimization method in this paper.The optimization reduces the working temperature of the friction plate,thereby reducing the overall temperature of the clutch,extending the service life,saving maintenance costs,improving the stability of the clutch,and provides a theoretical reference for parameter optimization of the friction plate structure.
