基于Ansys Workbench的电炖锅包装设计与仿真分析

目的优化电炖锅包装,比较EPS与瓦楞纸内衬的包装效果,以及替代可能性。方法参考电炖锅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,通过模态分析、随机振动、跌落等情况,分析得到不同力学载荷作用下产品的变形、应力、应变,以及破损情况,通过改变包装内衬实现电炖锅的包装优化设计。对优化后的包装件进行仿真分析,并与原包装件进行比较。结果最大应力出现在产品的螺栓连接处。裸机、EPS泡沫包装件和瓦楞纸(B楞)包装件的最大应力分别为353.25,115.69,171.84 MPa。结论瓦楞衬垫的抗压强度、抗冲击性能、抗振性虽都差于EPS泡沫包装,但还是可以很好地保护电炖锅,因此具有良好包装结构设计的瓦楞纸包装可以取代传统EPS泡沫包装。

Packaging Design and Simulated Analysis of Electric Cookers Based on Ansys Workbench

The work aims to optimize the packaging of electric cookers, and compare the packaging effects and alternative possibilities of EPS and corrugated liners. With reference to the environmental parameters of the electric cookers during the product flow, the finite element modeling and constraint processing were performed on the product. Based on the finite element concept in Ansys Workbench, the deformation, stress, strain and damage of the product under different mechanical loading effects were obtained through modal analysis, random vibration and drop. The packaging design of the electric cooker was optimized by changing the packaging liner. The optimized package was subject to the simulated analysis and compared with the original package. The maximum stress occurred at the bolted joints of the product. The maximum stresses of bare metal, EPS foam packaging and corrugated (B fluted) packaging were respectively 353.25, 115.69, 171.84 MPa. Although the compressive strength, impact resistance and vibration resistance of corrugated liners are all worse than EPS foam packaging, they can still protect electric cookers well. Therefore, corrugated packaging with good packaging structure design can replace traditional EPS foam packaging.
