A method for creating a multibody dynamics leaf spring model

Abstract

This invention provides a method for creating a multibody dynamics leaf spring model. First, the radius R of the front arc curve of the leaf spring is measured. f , arc included angle A f The radius of curvature R of the rear circular arc curve r , arc included angle A r And create these four parameter variables; then randomly create 22 coordinate reference points f0, f1...f on the leaf spring. 10 r0, r1...r 10 Select reference points f0 and r0 as the base points; then modify the reference point f. N and r N The coordinates are determined; after modification, the spring width is input using reference points and dynamics software to create a component with a small mass block; and the coil lug and swing lug are created to complete the single-piece leaf spring modeling. This invention's leaf spring model creation method uses geometric center lines and sine and inverse sine function theory to model from point to point, and then from point to solid. No additional plugins are needed during the modeling process, effectively reducing modeling costs and increasing efficiency. Modeling only once and can be applied to various leaf spring models by changing the parameters, making it highly practical.
