摘要:
针对机械式停车设备故障频发问题,以市场占有率较高的两层升降横移类机械式停车设备为研究对象,采用CAD/CAE技术开展框架结构模态分析与试验研究。首先利用SolidWorks和ANSYS软件建立框架结构三维及有限元模型,开展理论模态分析;然后利用AVANT MI-7008一体式数据采集与分析仪开展模态试验测试,并通过Modal Genius软件处理试验数据,分析得到停车设备各阶固有频率及振型。最后将试验结果与理论分析进行比对研究,分析结果表明停车设备的有限元模型是正确的,理论模态分析方法是可行的,该方法为停车设备的设计与优化提供有效参考和理论基础。

Abstract: Aiming at the problem of frequent failure of mechanical parking equipment, the modal analysis and test of the frame structure of a two-layer lifting and transversal type mechanical parking equipment with high market occupancy rate are studied by using CAD/CAE technology. First, the three-dimensional and finite element models of the frame structure are established by using SolidWorks and ANSYS software, and theoretical modal analysis is carried out. Then, modal tests are carried out by using the AVANT MI-7008 integrated data acquisition and analyzer. The test data are processed by Modal Genius software, and the natural frequencies and vibration modes of the parking equipment are obtained. Finally, the experimental results are compared with the theoretical analysis. The comparison results show that the finite element model of parking equipment is correct and the theoretical modal analysis method is feasible. This method provides an effective reference and theoretical basis for the design and optimization of parking equipment.
