1前言配管系统的振动,有时与小口径配管等的振动干扰有关,特别是在泵起动、停止时等过渡性运转状态下,也有空气混入等不确定因素,针对配管振动在疲劳强度方面的评价是重要的。现在已经开发出以小口径分支管为对象,实际加速度数据为基础,评价、
1 Introduction Vibration of the piping system is sometimes related to vibration disturbances such as small-diameter piping. Especially in the transitional state such as starting and stopping of the pump, there are uncertainties such as air mixing. In view of the fatigue strength evaluation of piping vibration, is important. It has been developed to small diameter branch pipe as the object, based on the actual acceleration data, evaluation,
