基于ANSYS Workbench的全向运输车体框架仿真分析

Simulation Analysis of Omnidirectional Transport Car Body Frame Based on ANSYS Workbench

以某全向运输车体框架为分析对象,运用SolidWorks三维软件对框架进行三维建模,并通过ANSYS对框架结构进行有限元分析,探究框架结构在实际工况下的应力、应变和变形情况。通过静力学强度分析可知,框架结构的强度满足所选材料的设计要求,同时结合变形云图发现,结构的变形量很小,满足实际设计要求。最后根据结构的布局情况,对框架结构进行了在外加载荷条件下的模态分析,探究了框架结构的固有振动频率,进而为驱动电机的选择和运行速度的选取提供参考依据。

Based on an omnidirectional transport vehicle body frame as the analysis object,used the SolidWorks three-dimensional software to model the frame,and the frame structure was analyzed by finite element analysis through ANSYS to explore the stress,strain and deformation of the frame structure under actual working conditions.Through static strength analysis,it is known that the strength of the frame structure meets the design requirements of the selected material.At the same time,combined with the deformed cloud diagram,it is found that the strain of the structure is small and meets the actual design requirements.Finally,according to the layout of the structure,the modal analysis of the frame structure under the condition of applied load is carried out,and the natural vibration frequency of the frame structure is explored,which provides a reference and basis for the selection of the drive motor and the selection of the operating speed.
