设备抗震强度谱是以设备为主体,反映设备本身最大抗冲击震动能力的试验准则。本文将这个概念推广于具有线性系统部件的设备,并提出了确定具有线性系统临界部件的设备抗震强度谱的试验方法。文章还提出了根据已经得到的强度谱预测设备在预定的具体环境冲击震动下是否会发生破坏的方法。 The seismic intensity spectrum of the equipment is based on the test principle of the equipment, which reflects the maximum impact shock resistance of the equipment itself. This article extends this concept to devices with linear system components and proposes test methods for determining the seismic intensity spectrum of devices with critical components of a linear system. The article also proposes a method of predicting whether a device will fail under a predetermined specific environmental shock shock based on the obtained intensity spectrum.
