【摘要】：目的对单层E型瓦楞纸箱托盘进行稳态分析,以便能对其结构进行优化设计。方法首先借助弹性力学理论,通过微分方程法对单层E型瓦楞纸箱托盘的临界载荷进行推导;然后通过UG(Unigraphics NX)对单层E型瓦楞纸箱托盘进行建模,利用试验测定的单层E型瓦楞纸箱托盘的工程常数,通过有限元法(FEM),在Ansys平台上对单层E型瓦楞纸箱托盘进行静态分析和屈曲分析,求解单层E型瓦楞纸箱托盘的屈曲模态和临界载荷。对理论方法推导和FEM试验验证的结果进行定性分析。结果对比分析结果,仿真结果和理论推导的结果具有一致性,两种方法对比验证,为E型瓦楞纸箱的结构设计提供了理论参考。结论理论方法推导和FEM对单层E型瓦楞纸箱托盘进行稳态分析,能够缩短产品设计周期,提升产品市场竞争力。
[Abstract]:Aim to analyze the steady state of single-layer E-type corrugated tray so as to optimize its structure. Methods the critical load of single layer E corrugated box tray was deduced by differential equation method with the help of elastic theory, and then the model of single layer E type corrugated box tray was established by UG(Unigraphics NX. Using the engineering constant of the single layer E corrugated box tray, the static analysis and buckling analysis of the single layer E type corrugated box tray were carried out on the Ansys platform by using the finite element method (FEM). The buckling mode and critical load of single layer E type corrugated tray are solved. The results of theoretical method derivation and FEM test verification are analyzed qualitatively. The results show that the results of simulation and theoretical derivation are consistent. The two methods are compared and verified, which provides a theoretical reference for the structural design of E type corrugated box. Conclusion theoretical method derivation and FEM steady state analysis of single layer E corrugated box tray can shorten the product design cycle and enhance the market competitiveness of the product.
