含液管(一般指输水管和输油管)横向振动是常见的振动类型之一。它的特征是沿管轴线弯曲变形,故又称为梁型振动。对这类振动附加质量的计算,目前仍沿用五十年代初的陈旧方法,即假定附加质量等于管道单位长度的液体质量。本文主要考虑振动过程中管壁的弹性变形,导出附加质量的理论计算公式,并经简单的实验加以验证,以期用于普遍性的管道工程。 Fluid-containing tubes (generally pipes and tubing) Horizontal vibration is one of the most common types of vibration. It is characterized by bending along the axis of pipe deformation, it is also known as beam-type vibration. The calculation of the added mass of such vibrations is still based on the outdated method of the early 1950s, assuming that the additional mass is equal to the mass of liquid per unit length of pipe. In this paper, we mainly consider the elastic deformation of the pipe wall during the vibration process and derive the theoretical formula of the additional mass, which is verified by a simple experiment in order to be used in the general pipeline engineering.
