模型转子 meaning in English

model rotor

An fem model of rotor - bearing system was set up for a single - span - two - disc test rig to obtain such model parameters as the first and second order natural frequency and vibration mode vectors
摘要以某单跨双盘模型转子实验台为例，建立了该转子轴承系统有限元模型，得到转子系统前两阶固有频率和振型向量等模态参数。
If the system parameter is known , the unbalance can be acquired from the response without adding trial mass , the responses are obtained from the program which emulates the real responses , correspondingly , the unbalance can be acquired by adding trial mass if the system parameter is unknown
当系统的参数已知时，不加试重的对转子不平衡作了识别；当系统参数未知时，通过加一次试重的办法来提取不平衡量。文中以一简单模型转子为例对方法的有效性作了检验。
