Because the shell model of industry oil bottle is complex and so it is difficult to create lubricating oil model, analog analysis was applied to simulate drop of full oil bottle. Firstly drop simulation was carried out on the vacant oil bottle; secondly a similar rectangle solid model is used to substitute the original oil bottle; and vacant bottle and full bottle drop simulation were carried out based on this model. Finally drop Von Mises stress was calculated based on analog analysis of this model. The proposed method is meaningful to some practical industry package product filled with liquid.
