AI Technical Summary
In traditional suspension designs, the linear stiffness and roll stiffness of the suspension are coupled, which limits the performance of the racing chassis and makes it difficult to improve lateral grip and ride comfort at the same time.
A decoupled suspension design method is adopted, in which a lateral pitch spring provides linear stiffness and an oblique roll spring provides roll stiffness. The linear stiffness and roll stiffness of the suspension are calculated separately, and the suspension parameters are optimized by Adams modeling and simulation analysis to achieve decoupling of the linear stiffness and roll stiffness of the suspension.
It improves the handling stability and smoothness of the race car, and enhances the lateral grip limit and overall performance of the race car.
