发布时间：2019-04-19 20:29
【摘要】：目的研究提梁开口塑料桶和无提梁开口塑料桶等2类危险品包装用桶的跌落力学响应。方法建立含有液体内盛物的2类塑料桶跌落有限元模型,并获得2类塑料桶在不同跌落高度下的应力场。结果提梁塑料桶的易渗漏位置位于桶顶,无提梁塑料桶的易渗漏位置位于桶体与地面接触处;无提梁塑料桶抗跌落冲击的性能优于提梁塑料桶。结论在设计开口塑料桶过程中,应关注桶顶的形状与尺寸设计,以减少液体冲击桶顶引起的应力集中。
[Abstract]:Objective to study the drop mechanical response of plastic barrel with beam opening and plastic barrel without lift opening for packaging of dangerous goods. Methods the finite element model of the drop of two kinds of plastic drums containing liquid contents was established and the stress fields of the two kinds of plastic drums were obtained under different drop heights. Results the easy leakage position of the lifting beam plastic barrel was located at the top of the bucket, and the easy leakage position of the non-lift beam plastic barrel was located at the contact between the barrel body and the ground, and the anti-drop impact performance of the non-lifting beam plastic barrel was better than that of the lifting beam plastic barrel. Conclusion in the process of designing the open plastic barrel, the shape and size design of the barrel top should be paid attention to in order to reduce the stress concentration caused by the liquid impact on the barrel top.
