摘要
利用冲击振动检测建筑工程结构的强度,用激光自混频干涉测振的方法,通过对模拟冲击振动信号的理论分析和计算,给出振动频率与振幅的关系,为判断可能引起建筑物损坏的振动提供依据.
Using the impact vibration testing architectural engineering structure intensity with a measuring vibration method of laser self-mixing interference, through simulating impact vibration signal, the vibration frequency and the oscillation amplitude relations are presented. It provides the basis for judging vibration to cause building damages.
