有以下三句话
1.The frequency of the response vibrations to an exciting force corresponds to the frequency of this force.
2.The frequency of the rotor lateral vibrations due to unbalance will be the same as the rotational speed.
3. In industry, the frequency of vibrations is usually related as ratios of the rotational speed; thus, the unbalance- related synchronous lateral vibrations are referred to as (1x) vibrations.If the rotor system is nonlinear, which is usually the case to a certain degree, then, in the system, more frequency components can be generated in
response to an exciting force of a single frequency.
第一句讲响应频率与激励力频率有关;第二句讲不平衡转子的摆振频率与转速一致。
疑问是:
(1)转子在匀速转动时,是否可以将转子不平衡量看作周期激励力,如果可以的话不平衡转子的响应频率与摆振频率有什么区别?如果没有区别的话第一二句是否矛盾
(2)在第三句中,if the rotor system is nonlinear, which is usually the case to a certain degree是否说非线性转子系统与多自由度系统等价?在多自由度系统中为何会有多个频率的响应?
英文来源《rotordynamics》
