摘　　要：对电厂管系水击激发的管道振动进行了研究,利用有限元方法,对研究的管系进行了有限元建模,把水击基本方程得出的水击力作为加载力,计算出了水击激发的位移、转角响应幅值和激发出的管系模态系数,从计算结果看出水击对管系的动力特性有重要影响,在管道设计时必须加以考虑,最后提出了消除水击影响的措施。Study on power piping system vibration from water hammer is processed. With FME method, piping system modal is set up, water hammer force is solved and is as external force to applied to piping system, and amplitudes of translations and rotations of piping system is calculated out. From these results, It is evidence that water hammer influences very important on the piping system .In the piping system design phase, it is important to take into consideration the water hammer effect. Some measures are put forward about reduction harm from water hammer on the piping system.
