摘　　要：在汽车车身开发中,采用尺寸工程技术可以帮助工程设计人员对车身功能尺寸进行控制。通过工艺和数模等的输入,制定车身定位策略,用尺寸链分析其功能尺寸的可行性并优化改进,最终输出最优的定位策略、公差及测点等尺寸工程文件。在理论分析的基础上,对车身功能尺寸的控制给出了一系列的优化方案,以最优化的周期和成本保证了其功能品质的合格。In automobile body development, dimension engineering technology can help the engineers to control the automobile body function size. The process and model are input, making strategy of automobile body positioning, the feasibility of its function dimension by dimension chain is analyzed and optimized. Finally, the final optimal dimension engineering file, such as positioning strategy, the dimension tolerance and measuring point, etc is output. In the paper, according to analysis how to control the body function size, a series of optimization program is provided, which can guarantee its quality of function size in the optimum cycle and cost.
