为防止共振发生，电动机的工作频率应远远小于其固有频率。

In order to keep the normal operating state of a electro motor, the working frequency of the electro motor should be much lower than that of natural frequency.

介绍常见的汽车振动噪声隔离技术，其中对能有效防止共振发生的整车模态频率规划表进行详细介绍。

The table of programming natural frequencies which layouts the natural frequencies of all subsystem of the vehicle in the process of design is one of the effective ways to isolate resonance.

如果压缩机(12)或真空泵(10)非常强烈地振动，那么因此能够简单地修改驱动马达(14)的转动频率以防止共振效应。

If the compressor (12) or the vacuum pump (10) vibrate too strongly, the rotative frequency of the drive motor (14) can thus be simply modified to prevent resonance effects.
