摘　　要：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 discharge pipes are simulated by the multiple frequency waves while the pump plugs move back and forth. By means of finite element method, a mathematical model of the structural vibration of discharge pipes is built. The design rules of reducing or eliminating vibration in practical engineering are summarized.
