组件式塑料周转箱结构设计

目的设计卸货时更省时省力的塑料周转箱。方法运用Pro/E软件设计可折叠侧开式塑料周转箱和插板式塑料周转箱,利用Ansys Workbench软件仿真获得组件式塑料周转箱在静态和动态跌落过程的应力、应变和变形等情况。结果塑料周转箱的最大堆码应力发生在侧板底部,最大应变极其微小;角跌落时,应变主要集中在底板、侧板和连接轴上,底板与地面接触点的等效应力最大,其他的最大等效应力都很小。结论周转箱的设计满足强度要求,该设计方案可行。

Structural Design of Modular Plastic Crate

The work aims to design a more time-/labor-saving plastic crate. Foldable side-open and plate-inserted plastic crates were designed by Pro/E software. The Ansys Workbench software was adopted for simulation to obtain the stress, strain and deformation of the modular plastic crate in static and dynamic drop process. The maximum stacking stress of the plastic crate was at the bottom of the side plate, and the maximum strain was extremely small. The strain was mainly concentrated on the bottom plate, side plate and connecting shaft, the equivalent stress at the part where the bottom plate and the ground contacted was the maximal, and the maximum equivalent stress of all other parts was small in the angular drop. As the crate design meets the strength requirement, such design scheme is feasible.
