摘要
车轮的可靠性对高速列车的安全性至关重要。因此,利用ANSYS在考虑离心力作用的状态下对CRH380BL高速动车车轮进行有预应力的模态分析。首先在Pro/E中对车轮进行建模并对模型进行适当简化,然后将模型导入ANSYS并进行网格划分。经过由离心力导致预应力的静力分析,进而进行有预应力的模态分析得到了该车轮前10阶固有频率、振型及相对位移分布图,分析结果为车轮的结构优化及进一步动力学分析提供了必要依据。
The reliability of train wheels is essential for the security of high-speed trains. Modality analysis is done on CRH380 BL high-speed wheels by considering the centrifugal force with the finite element software ANSYS. First,the geometric model of wheel is founded by Pro/E and a proper simplification is made. Then it is partitioned using grid meshing method. The static analysis of wheels is carried with centrifugal force. The eigenvalues of wheel are extracted in ANSYS based on block lanczos algorithm and the solution offers the first ten natural frequencies,vibration modes and the map of related displacement. The analysis results provides indispensable evidence for structure optimization and the further analysis of dynamics.
