泵的往复运动导致输液管道受多频率谐波激励。用有限元方法，建立管网系统结构振动分析模型，求得固有频率和振型分布，给出有工程实用价值的管道减振、消振的设计原则。
The reciprocating motion of the pump causes the tubing to be excited by multiple frequency harmonics. The finite element method is used to establish the structural vibration analysis model of the pipe network system, and the natural frequency and mode shape distribution are obtained. The design principles of damping and vibration damping of the pipe with engineering practical value are given.
