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.
