以一款特定结构的木塑托盘为研究对象,基于托盘结构和连接方式两方面考虑,以托盘实验过程中的实际承载条件为依据,分析了其可能存在的失效模式,通过实验研究确定了其评价指标。 在 Ansys Workbench 环境下建立结构模型,对 2 种失效模式进行了模拟,分析了整体结构及螺栓连接在静态弯曲下的承载特性。 通过进一步分析比较,验证了材料结构的性能要求和设计的合理性。

Specific WPC pallet was taken as an object of study. The possible failure modes of the pallet were analyzed considering the pallet structure and combination pattern. The evaluation indexes were determined through experimental study based on the actual bearing capacity. The structure models were established in Ansys Workbench environment and two failure modes were simulated. The bearing characteristic of over-all structure and bolted connection under static bending was analyzed. The performance of material and rationality of design was verified through further analysis.
