摘要
用有限元法计算分析了同步电动机转子在滑动轴承-机座支承系统下的不平衡响应特性。分析结果表明,在同步电动机的转子上填加不平衡量时,转子系统则激发一阶分量,其不平衡响应特性发生变化,为指导同步电动机组的动平衡奠定了基础。
The calculating unbalance response of the rotor-bearing system is vital important in rotordynamic device.Finite buck arithmetic is one of methods.For TAW8800 synchronous machine,rotor unbalance response characteristics of rotor are analyzed using finite buck arithmetic method.The result shows that the 1st mode can be excited in the same time with 1st mode unbalance distribution.It is very important for rotor balance in the engineering field.
