| 摘 要： | 建立了高速铁路轴承试验台主轴的参数化有限元模型,利用有限元分析软件ANSYS对主轴进行了模态分析,初步判定主轴会发生共振。对主轴结构进行了优化计算,结果表明,该方法确立了支承轴承的位置,主轴在自重减轻的情况下提高了其一阶固有频率,改善了主轴的动态性能,并且有效地避开了共振区。 |

| Abstract: | The finite element model of main spindle in the test rig for high-speed railway bearing is established,and the modal analysis of main spindle is carried out by using the finite element analysis software ANSYS.The preliminary determination is that spindle resonance occurs,and the optimized calculation for spindle structure is conducted.The results show that the position of support bearings is determined,the first natural frequency is increased by reducing spindle weight,the dynamic performance of the spindle... |
