中文摘要：

针对定制产品变型设计中设计参数不完全的问题，提出了在客户提出尺寸变化范围基础上进行均匀设计的优化变型设计方法。在该方法中，首先建立产品主模型，对尺寸参数建立一个尺寸向量，定制产品中的未知尺寸可以通过均匀设计的方法取得。然后关联产品尺寸，驱动CAD变型设计系统，得到定制产品模型，并给出了均匀设计在变型设计中的步骤和过程。通过均匀设计方法．减少了实验次数，提高了设计效率，优化了产品性能。最后通过一个实例详细地描述了均匀设计在变型设计中的应用。

英文摘要：

Aiming at the problem of incomplete design parameters data in variant design of customized product, we present an optimization variant design method based on uniform design. The parameters were based on dimension method. Then we relate product dimensions with CAD （Computer Aided Design） variant design system, and produce the new product model required by the customer. The steps and processes of optimization variant design based on uniform design were put forward. The times of experiment are reduced and efficiency is enhanced through the uniform design method. Finally, the application of this method of the variant design is fully described through an example.
