Abstract: UG and Hypermesh software were used to build and mesh the air-conditioner outside unit model, and ABAQUS/Explicit software was used to simulate different kinds of the air-conditioner outside unit dropping process. The simulation results turned out that the left brace and the right rear board which need further strengthen were easy to become plastic deformed during dropping process. And the damage degrees of different dropping directions were compared in this paper.

Key words: Dropping, Air-conditioner outside unit, Finite element method, ABAQUS/Explicit
