在图5中可以看到，在稳态条件下，露营车的振动响应存在三个明显的峰值：49.2 Hz，100 Hz和300 Hz。根据压缩机的激励特性，内部偏心质量转子在旋转过程中会产生不平衡的惯性力[4]，其频率与稳态条件下的工作频率[4、5、17]相同。电机的电源频率为50 Hz。根据电动机在气隙磁场中的内部电磁力的特性，在100 Hz和300 Hz处的振动是由径向电磁力引起的谐波振荡，在所有三个工作条件下都存在。

It can be seen in Figure 5 that there are three obvious peaks for the vibration response in the camper under steady-state conditions: 49.2 Hz, 100 Hz, and 300 Hz. According to the excitation characteristics of the compressor, the internal eccentric mass rotor generates an unbalanced inertial force [4] during the rotation, and the frequency is the same as the operational frequency under steady-state conditions [4, 5, 17]. The power frequency of the motor is 50 Hz. According to the characteristics of the internal electromagnetic force of the motor in the air gap magnetic field, the vibration at 100 Hz and 300 Hz is harmonic oscillation caused by the radial electromagnetic force, which exists at all three operational conditions.<br>
