碳纤维麦弗逊悬架控制臂铺层优化OA

According to the hard point load of suspension under three limit conditions,based on the classical laminate theory of composite materials and the laying design method of symmetrical balance,the fiber laying angle of composite control arm is designed,and the laying optimization design is carried out by using OptiStruct software to correlate four single layers with one super layer.Furthermore,the areas that need to be strengthened are obtained by the method of topology analysis,and the shape optimization design of the control arm is carried out by using the layer size optimization method,which can reduce the weight by 64%compared with the original metal structure on the premise of meeting the application requirements.A lamination optimization method for non-uniform cross-section structures is proposed,which has a certain guiding significance for the lamination optimization of composite structures with complex cross-sections.
