| 摘 要： | 对加工中心电主轴整机主轴-轴承-电动机-轴承座等进行动力学有限元建模,并通过物理实验对整机模型进行了验证。对比有限元分析结果与物理实验结果表明:前3阶固有频率吻合程度高,误差较小;频率在3 kHz以上时,误差显著增大。通过物理实验的验证表明:建立的有限元模型在预测电主轴低阶固有频率是有效的,该分析模型对主轴的动力学响应、结构优化设计等有着重要的意义。 |

| Abstract: | In this paper the dynamic modeling of motorized spindle whole-body,which is equivalent to the shaft-bearing-motor-bearing housing-system,is conducted using the finite element method and verified by physical experiments.The results indicate that the first three sets obtained by FEA coincide with those obtained by physical experiments approximately,the inaccuracy is subtle.However the deviation increases considerably when the analysis frequency is higher than 3 kHz.The finite element model founded in this pap... |
