在通信设备抗地震性能检测中设备固有频率是判断抗震性能的重要依据,本文阐述几种固有频率的测试方法,针对弹性器件探讨固有频率变化规律,分析对弹性器件固有频率影响的原因。
In the anti-seismic performance of communication equipment, the natural frequency of equipment is an important basis for judging the anti-seismic performance. Several test methods of natural frequency are described in this paper. The variation rules of natural frequencies are discussed for elastic devices and the reasons for their influence on the natural frequency of elastic devices are analyzed.
