摘要: 基于显式动力学理论,本文对冰箱进行跌落仿真分析并提出优化方案。依据相关标准对冰箱正跌与后角跌落两种工况进行仿真分析。仿真结果显示冰箱采用原方案的包装底垫进行跌落时,冰箱的发泡腿应力大于材料的屈服极限,且压缩机底板变形量达到10.7mm超过试验标准允许范围。试验结果原方案包装底垫不能通过跌落测试。结合仿真分析与动力学相关理论提出包装底垫的优化方案。底垫优化方案仿真计算结果显示冰箱跌落冲击加速度、发泡腿应力以及压缩机底板变形均小于原方案的跌落数据。经过试验验证底垫优化方案通过测试。

Abstract: Based on the explicit dynamics theory, this paper analyzes the drop simulation of the refrigerator and proposes an optimization scheme. According to the relevant standards, the simulation analysis was carried out for the two conditions of the refrigerator falling and the rear corner falling. The simulation results show that when the refrigerator is dropped using the original package bottom pad, the foaming leg stress of the refrigerator is greater than the yield limit of the material, and the deformation of the compressor bottom plate reaches 10.7mm exceeding the allowable range of the test standard. Test results show that the original package bottom pad cannot pass the drop test. Combined with simulation analysis and dynamics related theory, an optimization scheme for packaging bottom pad is proposed. The simulation results of the bottom pad optimization scheme show that the drop impact acceleration, foaming leg stress and compressor floor deformation are smaller than the original drop data. The test proved that the bottom pad optimization scheme passed the test.
