摘要
通过一个柔性基础上安装电机的隔振系统实例 ,计算其通过隔振器的功率流 ,应用功率流传递谱对其隔振性能进行分析评估 ,并附带研究了电机槽频频段的振动隔离问题。探讨了功率流分析在隔振设计中的可行性 ,以及功率流评估指标与振级落差指标之间的内在联系。
The method of power flow analysis is discussed and performed from the view point of theory and practice, for an example of a motor mounted on flexible foundation. The power flow transmitted through the isolators is calculated, and the effectiveness of the isolation system is estimated. The theoretical analysis is given on a vibration isolation problem associated with the motor chamfer frequency that occurs in some practical systems. The practicability analysis of the power flow evaluation criterion and the relationship between the vibration level and transmitted power flow are presented.
