摘要
运用SolidWorks对某剪叉式升降机的底座承重框架进行三维建模,并通过ANSYS对承重框架结构进行有限元分析,探究承重框架结构在实际工况下的应力、应变和固有振动频率。静力学分析结果表明:承重框架结构的强度满足设计要求,但局部变形量过大。在此基础上对底座承重框架结构进行优化,对结构优化后的底座承重框架再进行有限元分析,整体变形量下降了50.74%,满足设计指标要求。最后对优化后的底座承重框架结构进行了模态分析,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设定提供了参考和依据。
Use SolidWorks to build a three-dimensional model of the load-bearing frame of the base of a scissor lift,and conduct a finite element analysis of the structure through ANSYS to explore the stress,strain and natural mode frequency of the load-bearing frame structure under the actual working conditions.The static analysis results show that the strength of the frame structure meets the design requirements,but the local deformation is too large.On this basis,the substructure load-bearing frame structure was optimized,and the substructure load-bearing frame after structural optimization was analyzed by finite element method,and the overall deformation decreased by 50.74%,meeting the design index requirements.Finally,the modal analysis of the load-bearing frame structure is carried out,and the natural vibration frequency of the frame structure is explored,which provides reference and basis for the selection of driving motor and the setting of running speed.
