摘　　要：针对一种复合材料盒状波形弹簧减震件进行了优化设计、数值仿真和试验验证。在设计过程中分别对铺层位置、铺层方向和铺层厚度进行优化,结合实际制造等因素,给出3种工艺可行的设计方案并进行了数值仿真计算。采用碳纤维预浸料,利用模压法分别制备了3种方案的试验件并进行静力试验验证。以位移质量比作为评价标准对3种方案进行评价,结果表明优化得到的全0°渐变铺层的方案在满足规定承载要求的同时,拥有最轻的质量和最大的变形裕度;另外试验值和仿真值相差不是很大,说明该优化过程具有一定的借鉴意义。In this paper,design optimization,numerical simulation and experimental verification of a composite box wave spring shock absorber were carried out. During the process of design,the position,the direction and the thickness of the layer were optimized to provide three feasible design schemes according to actual manufacturing factors. Based on the three schemes,three kinds of test pieces made from carbon brazing prepreg were manufactured by molding method and then verified by static test. The three schemes were further evaluated using displacement mass ratio as the evaluation standard. The results showthat full 0 degree gradation layer as one of the three optimized schemes has the lightest quality and maximum deformation margin,while it satisfies the loading requirements. The difference between the test value and the simulation value is not very large,which shows that the optimization process is significant for providing a reference.
