基于 Ansys 的数控立体仓库升降车底座优化

目的为了减轻数控立体仓库升降车底座的质量,从而保证其结构强度满足要求,现利用有限元模拟升降车底座性能。方法先通过Solidworks 2010完成升降车底座的建模,再导入有限元分析软件Workbench分析其结构强度,根据分析结果修改模型,直至其结构强度满足要求。结果通过改变升降车底座的厚度和结构得出不同受力以及变形情况,并对试验结果加以分析和优化。结论厚度为4 mm的底座通过增加加强筋,结构强度满足要求,质量比厚度为5 mm底座减少20.01 kg,节省了材料,提升了系统整体的性能。

Optimization of Lifting Truck's Chassis of NC Warehouse Based on Ansys

Objective To reduce the weight of lift truck's chassis of NC warehouse and guarantee its structural strength to meet the requirements. Finite element was used to simulate the performance of lift truck's chassis. Methods Solidworks 2010 software was used to create the 3D model of Lifting truck's chassis of NC warehouse, and then Ansys software workbench was introduced for finite element analysis of structural strength. According to the results, the model was modified until the structural strength met the requirements. Results Different force and deformation were obtained by changing the thickness and structure of the Lifting truck's chassis, and the test results were analyzed and optimized. Conclusion After increasing the stiffener, not only the structural strength of the chassis with 4mm thickness met the requirements,but its quality was also reduced by 20. 01 kg as compared to the chassis with 5mm thickness,which saved materials and improved the overall performance of the system.
