The direct analysis method is based

The direct analysis method is based on coupled thermal structural units..(1) to establish geometric models and material modelsThe geometric model and material model are the same as the thermal load characteristic analysis.. Due to the limitation of computing time, only the first startup process is simulated here..(2) determine the boundary conditionsMake connections:Establish the contact pair between the friction plate of the intermediate drive plate and the pressure plate friction plate..Determine the thermal boundary conditions:Determine the boundary conditions of heat dissipation (thermal convection, thermal radiation), the same as the thermal load characteristic analysis..Determine displacement boundary conditions:The speed of the friction plate with Δ n pivoting; The middle drive plate imposes a complete restraint on its lugs; The pressure plate limits the displacement of the x and Y axes at its lugs and applies a force in the z direction. Clutch heat is generated on the friction surface between the friction plate and the pressure plate. The heat generated is equal to the sliding friction work of the clutch. This heat dissipates in various ways, and the rest accumulates in the clutch, raising the temperature of the clutch parts. The heat dissipation of the clutch is carried out by three basic modes of heat transfer, that is, heat conduction, heat convection and heat radiation.
