摘要: 根据ASME OM-S/G-2000 Part 3的要求,通过理论分析及相关经验介绍了选取管道振动测量点的一般原则。推导了几种结构形式管道的振动位移和速度的限值计算式。该方法可作为管道振动评定是否超标的基本准则,适用于对管道可能出现过大的振动应力进行安全监控。Abstract: According to the requirements of ASME OM-S/G-2000 Part 3,this paper presents the common principles of selecting the measuring points on the piping system by theoretical analysis and relevant experiences.Moreover for some specific piping systems,the allowable values of vibration displacement and velocity are derived,which can be used in assessing pipe vibration.It is helpful in the safety monitoring of the stresses caused by vibration.
