To establish drop impact simulation technology of air conditioning outdoor units, firstly, we made constitutive equation of the packing materials and confirmed its precision by drop impact experiments of test pieces. Next, we conducted drop impact experiments and analyses of bottom frame installed a compressor and a weight to verify validity of the modeling of the sheet metal. Finally, we carried out drop impact experiments and analyses of an air conditioning outdoor unit to confirm validity of the modeling of screw joints of the sheet metals. This paper describes the development method for our drop impact simulation technology of air conditioning outdoor units, and introduces an example of the application of the simulation technology in the early development stages of air conditioning outdoor units.
