摘要:

工业油壶的三维壳模型形状复杂,不易在其基础上创建润滑油模型,为了能够对盛满的油壶进行跌落仿真,采用了类比分析的方式。首先对空油壶模型进行跌落仿真,然后用一个规则的与原油壶等外廓的长方形薄壁实体模型模拟空油壶,并在其内注入润滑油进行跌落仿真,根据类比分析推出了原油壶满载下的跌落应力。该方法对于某些工业产品的贮液包装物的跌落仿真,具有一定的参考意义。

Abstract:

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.
