设计了一种适用于管路系统减振的弹簧片式动力吸振器。该吸振器在结构上采用螺栓与管路进行连接，采用弹簧片质量块构成弹簧质量系统对振动进行吸收，具有结构简单、调频和安装方便的优点。对动力吸振器进行了结构设计并进行了参数选择，建立管路有限元模型分析了安装减振器前后系统的谐响应，最后进行了实验验证。实验结果表明，动力吸振器将共振频率下的振动降低了90%以上，与相同质量大小的质量块的减振效果的比较表明，吸振器的减振效果明显优于质量块的减振效果。

A new spring type of dynamic vibration absorber for pipe system vibration suppression was designed.The absorber connected with the main system by bolted connections,and leaf spring and mass were used to constitute the spring-mass system.The parameters of the vibration absorber were selected firstly,then the finite element model of the pipeline system was set up to analyze the har-monic response between pre-and post installation of the damper;finally,experiments were completed to confirm the system.The results show that:the vibration in the resonant frequency will be reduced 90% with the dynamic vibration absorber,the effects of block with the same mass as damper were compared,and the results show that vibration damping has a greater effect than that of mass.This de-signed dynamic vibration absorber can reduce pipeline vibration levels significantly,and have a good damping effect.
