摘　　要：在计算机模拟碰撞的基础上,对现有的儿童汽车安全座椅产品进行改型设计.首先,通过逆向工程的方法,建立儿童汽车安全座椅样件的三维CAD模型,根据市场实际需求对样件进行改型设计.然后利用MADYMO(mathematical dynamic model)软件建立虚拟碰撞仿真模型,并分别对改型前后的儿童汽车安全座椅进行了仿真碰撞试验.最后,通过对仿真碰撞结果的分析,验证了改型设计的可行性.Retrofit design of an existing child safety car seat is used based on computer simulating collision. Firstly, the sample’s 3D model of child safety car seat is built by using the technology of reverse engineering. According to the requirement of the market, retrofit design is used on the sample. Simulating models are built and the simulating collision tests of the samples before and after retrofit design are done respectively by using the software of MADYMO（mathematical dynamic model）. At last, the feasibility of the new design is proved by analyzing the test results.
