MULTI-TARGET OPTIMAL DESIGN FOR THE CONSTRUCTIONAL PARAMETERS OF PULL-TYPE DIAPHRAGM SPRING IN AUTOMOBILE CLUTCH

In this paper , with the load-deflection characteristics and stress-deflection characteristics analyzed in detail and all constrain conditions considered, a new multi-target optimal design mathematical model for the constructional parameters of pull-type diaphragm spring is brought up. This model can make the changes of the reservation coefficient and the changes of declutching force smaller before and after the clutch disc worn. The model is solved by TOPSIS ( Technique for Order Preference by Similarity to Ideal Solution ) . Design example shows that a just model is established in this paper and the modeling method has a practical significance.
