Optimization of flex-plate based on response surface method
The existence of dowel hole and lacking of signal gear teeth,making flex-plate structure irregular,have an impact on dynamic balance,which affects the property of flex-plate.Taking a certain flex-plate as an example,it was optimized by response surface method to improve the stiffness and strength property.The optimized model was built using least-square method,with the design factors of the change of flex-plate thickness,the rotating angle and the number of changed holes,and radius of the holes,constrained by removing weight,targeted as minimizing the stress of 0.5 mm axial displacement.The test showed that,this method could meet the requirement for removing weight,the maximum stress was reduced by 26.79%,obviously,axial fatigue strength of the flex-plate was improved.
