空调底板的结构优化与冲压成形仿真

以某空调底板为研究对象，对其进行了三维建模、结构优化及冲压成形仿真。在减薄空调底板厚度的情况下，采用ANSYS Workbench软件对底板进行多目标优化，使底板的刚强度同时满足要求；并对优化后的底板采用Dynaform进行冲压成形仿真，通过工艺参数的调整，使结构优化后的底板冲压取得较好的成形效果。结果表明：采用基于有限元法的数值仿真技术，大大缩短了产品开发周期，并降低了开发成本。

Structure Optimization and Stamping Forming Simulation of Air-conditioner Chassis

By taking one air-conditioner chassis as the study object, 3D modeling of it was processed, with structure optimization and stamping forming simulation. Multi-objective optimization was carried out to make the chassis to meet the requirements of stiffness and strength simultaneously by adopting ANSYS Workbench software in the case of thinning its thickness. Then stamping forming simulation was implemented for the optimized design using Dynaform software, and the forming effect was good at stamping forming of the optimized chassis through the adjustment of stamping process parameters. This result indicates the numerical simulation technique based on Finite Element Model (FED) has important significance in shorten the product development cycle and reduce development costs.
