摘要: 研究空调内机在跌落冲击工况下的力学行为。首先通过不同应变率的材料试验,建立LS-DYNA材料模型;然后通过DYNAIN方法建立整机连续跌落有限元模型,并将跌落仿真与试验进行对标。对标结果显示:连续跌落仿真与试验的加速度曲线相关度达到93{\%}以上,且破坏位置一致。结果表明该方法可以准确模拟空调内机在连续跌落工况中的力学行为,为家电产品研发设计提供重要的指导意义。

Abstract: The mechanical behavior of air conditioning under drop conditions is studied. Firstly, the LS-DYNA material model is established by material tests with different strain rates. Then the continuous drop finite element model of air conditioning is established by the DYNAIN method. In the meantime, the drop simulation and the test are benchmarked. The benchmark data show that the correlation between the continuous drop simulation and the experimental acceleration curve is over 93%, and the damage location is consistent. The results show that the method can accurately simulate the mechanical behavior of air conditioning under continuous drop conditions, which may serve as a guidance for the research and development of home appliances.

Key words: air conditioning, drop simulation, sequential drop, material experiment, strain-rate
