中文摘要：为解决某空调底盘成形过程中废料多的问题，本文利用有限元分析软件eta/DYNAFORM对空调底盘的坯料尺寸进行优化，得到了合理的坯料尺寸。用优化后的坯料尺寸模拟底盘成形过程，指导修边工序切刀的布置。通过模拟优化减小了下料尺寸，切边工序由四周全切边改为局部切边，成形过程中减少了废料，提高了材料利用率。通过坯料尺寸及工艺的优化，在保证制件合格的基础上材料利用率提高了8%，降低了成本，提高了经济效益，同时减少了试模时间。
英文摘要：In order to reduce the waste material of the air-conditioner chassis during the forming process. The finite element simulation software eta/DYNAFORM is used to optimize the blank size of the air-conditioner chassis in this paper and the reasonable blank size is obtained. The optimized blank size is used to simulate the forming process of the chassis and the result provides conduct for the arrangement of the cutters in the later trimming process. The blank size is decreased and the trimming process is changed from all sides trimming to part sides trimming through the simulation and optimization. As the waste material is reduced in the forming process, so the material utilization is improved. The material utilization increases almost eight percent than previous after the optimization of blank size and process, and on condition that the qualified part is obtained. So it saves the cost and improves the economic benefit, and at the same time it reduces the time of mold test.
