摘要
利用ANSYS有限元软件,对5.5 m捣固装煤车三维模型进行模态分析,得出其一阶振型和固有频率,同时设计了捣固装煤车的现场振动测试方案,并对测点实测数据进行了分析处理;通过测试数据和模态分析数据进行比较分析,检验有限元模型的准确性,对捣固装煤车模型进行了检验和修正;修正的有效模型为捣固装煤车结构振动特性设计提供了基础。
Using the finite element software ANSYS, to 5.5 m tamping charging car 3D model modal analysis, Come first-order vibration mode and natural frequency, While the design of the tamping charging car field vibration test program and the measuring point measured data were analyzed treatment; Comparative analysis of data through field testing and modal analysis of the data, the accuracy of the test finite element model of tamping coal charging car model was validated and corrected; Revised effective model for tamping loaded coal cars the vibration characteristics of the structure designed to provide the foundation.
