基于Ansys Workbench的吸尘器振动与跌落仿真

目的验证立式吸尘器整体包装方案优化设计的保护和安全性能。方法参考立式吸尘器产品流通过程中的环境参数,对产品进行有限元建模和约束处理,基于Ansys Workbench中的有限元思想,分别模拟运输过程中随机振动、刹车、转弯、跌落等各种物流情况,分析得到不同力学载荷作用下产品包装的变形、应力、应变以及破损情况。结果瓦楞顶衬开槽处的设计还有待改进,瓦楞纸箱在跌落时垂直方向上的变形和应变数值较小,不影响整体包装的安全性和保护性。结论瓦楞衬垫和瓦楞纸箱的抗压强度、抗冲击性能、抗震性均符合要求,该立式吸尘器整体包装方案合格。

Simulation of Vibration and Drop of Vacuum Cleaner Based on Ansys Workbench

The work aims to verify the protection and safety performances of the optimized design of overall packaging scheme of vertical vacuum cleaner. The finite element modeling and constraint handling of products were carried out by referring to the environmental parameters in the circulation process of vertical vacuum cleaner. The simulation of random vibration, braking, turning, drop and other logistics conditions in the transportation process was taken based on Ansys Workbench. The deformation, stress, strain and damage of the product package under different mechanical loads were obtained by analysis. The design at the slotting of corrugated top lining needed to be improved. In the vertical direction, the deformation and strain of corrugated box during the dropping were small, but they would not affect the safety and protection of overall package. The compressive strength, impact resistance and seismic resistance of corrugated liner and corrugated box conform to the requirements. The overall packaging scheme of vertical vacuum cleaner is qualified.
