Based on the analysis of the working characters of disc springs in clutch

the mathematical model of multi-objective optimal design of disc springs is established with unified objective function method

which regards the minimization of the disc spring volume and its average variable quantity of working compress force within the scope of friction lining wear as optimal objectives.The optimization calculation is presented by using the software modeFRONTIER.The results indicate that the relevant performance of disc springs is significantly improved after optimal design

with the objective function values reduced by 36% and 6% respectively.The software modeFRONTIER

with its simplicity and efficient algorithm

solves optimization problems and improves design efficiency.
