摘　　要：为了满足汽车空调的出风要求,空调出风口叶片要实现上下左右的运动。在以往的设计中,成品件通常会出现运动关系不正确、运动间隙不足及叶片定位不准确等设计缺陷,导致空调出风口不能正常运行。为避免此类设计问题的重复出现,应用CATIA软件的DMU模块进行辅助设计。主要阐述了如何应用CATIA DMU模块对某汽车空调出风口进行设计、校核及更改的设计方法。该方法能在设计阶段避免发生设计错误,减小重新开模及修模的几率,有助于整车成本的优化,提高工作效率,对今后的设计工作提供经验。In order to meet the requirements of automotive air conditioning systems, the vehicle air outlet blade should do vertical and horizontal movement. In the past design, the finished pieces often appeared incorrect movement, insufficient clearance, inaccurate positioning of blades, resulting in abnormal outlet operation. To aviod such problems, CATIA DMU modules aided design. This paper＂ focuses on how to use CATIA DMU module for a vehicle air outlet design, verification, and design modification. This method can avoid design errors in the design phase, reduce probability of re-open mode and repair＂ mode, reduce vehicle costs, improve working efficiency, and it will provide working experience for future design work.
