化工系统管道随机振动的应力识别

Identification of random vibration stress of pipelines inchemical engineering systems

本文提出了一种识别化工系统管道随机振动应力的方法，并根据简化的力学模型导出了求取识别参数（位移和速度）的限值公式，还提出了控制管道振动的技术方法。

method of identifying random vibration stress ofpipelines in chemical engineering systems was proposed.and the formulae of limited value of calculating identifica-tion parameters (displacement and velocityl were derivedbased on simplified mechanical fnodels. It was suitable tocarry out the safety monitoring when large vibration stressIevel in piping occurred in production in chemical plants.and technical methods of controllins pipeline vibralion wereproposed .
