Structural Optimization and CAE Simulation for Stamping Forming of Air-Conditioner’s Chassis Part

CAE simulation is carried out for the structural stiffness of outdoor air-conditioner’s chassis by adopting NX Nastran software.Based on the simulation results,the original design is improved and optimized,and the stiffness of the new design increases by nearly 50% compared with the original one.Then numerical simulation is implemented for the stamping forming process of the optimized design using Dynaform software,which results show that no crack or wrinkle will occur during stamping forming.Finally,experimental verification exhibits that the stiffness for the optimized design has been evidently improved with good quality in stamping forming.Therefore,CAE simulation has important directive significance in new product’s development.
