The Parallel Optimal Design Of Fraction Plate And Diaphragm Spring Based On Genetic Algorith

Clutch is a key device that used to cut off and connect the transmission of powersystem in the car．First of all the design requirements of automobile clutch is to ensurethat car can transfer the maximum engine torque at any driving conditions reliably,and has the appropriate torque reserve to prevent the transmission system beoverloaded．Secondly, the clutch driven rotary inertia must be small enough to reducethe impact between transmission gear．The structure should be as simple, compact,small quality as possible．As the key parts of the clutch the design of friction plate anddiaphragm spring will directly determine the clutch overall optimizationperformance．Building the digital modeling solution system by utilizing the geneticoptimization algorithm to quantificat the size parameters variables and plan the wholeconstraint conditions in order to achieve high performance clutch effect．The parallel optimal design of fraction plate and diaphragm spring in the frictiontype diaphragm spring clutch isn’t separately optimize the friction plate or thediaphragm spring to improve the overall performance．It is based on analysing thesame inside and outside work environment factors of friction and diaphragm springand being clear of the coupling relationship between them to improve th·e integratedoverall performance．Depending on each optimal target’s weight by the improved GAstrategy to get a more accurate global optimal solution rapidly and avoid getting into alocal solution．It can get a best work coperation state after the parallel optimal designof friction plate and diaphragm spring．At the same time, this project utilizes the software of Ansys to show the finiteelement analysis after the optimized design of diaphragm spring and friction plate by genetic algorithm．Contrasting the original and optimal solution it gets a betterperformance of clutch．This reveals the change regulars of clutch diaphragm springand friction plate and provides certain theoretical basis for the clutch optimization．...
