网箱托盘静动态力学性能的有限元分析

Finite Element Analysis of Static and Dynamic Mechanical Properties of Cage Pallet

目的以新制仓储设备网箱托盘为研究对象,利用有限元分析软件对其受力进行分析。方法通过Solid Works软件对网箱托盘进行建模,并在Ansys Workbench中进行结构静力学分析,Ansys LS-DYNA中进行跌落分析,获得应力、应变、位移云图及相关数据。结果结构静力学分析得到底托盘的最大应力为5.18 MPa,最大位移为1.2 mm;面跌落分析得到网箱最大应力为2 MPa,底托盘最大位移为16.51 mm。结论网箱底托盘无支撑位置的变形较大,受损严重。该研究能够为网箱托盘的结构优化提供依据。

With the new warehouse equipment cage pallet as the research object, the work aims to study its state of force by finite element software. Model of the cage pallet was established by Solid Works software, and structural statics was analyzed in Ansys Workbench and drop analysis was conducted in Ansys LS-DYNA. The related stress, strain, displacement and data were obtained. Analysis of structure static showed that the maximum stress of bottom pallet was 5.18 MPa, and the maximum displacement was 1.2 mm. Surface drop analysis showed that the biggest stress of cage was 2 MPa and the maximum displacement of the pallet at the bottom was 16.51 mm. In conclusion, the part of cage bottom tray where no support is applied is seriously deformed and damaged. This study provides a basis for the structural optimization of cage tray.
