| 摘 要： | 为了拓宽传统定参数颗粒阻尼吸振器的有效减振频带，设计了一种变质量颗粒阻尼吸振器。对变质量颗粒阻尼吸振器的动力学特性进行了仿真及实验研究，并利用数据拟合的方法建立了颗粒容器内水量与最佳减振频率的变化关系。研究结果表明：变质量颗粒阻尼吸振器可以通过改变颗粒容器内的液体量调节其最佳减振频率，拓宽了吸振器有效减振频带。

| Abstract: | In order to extend the effective frequency band of a conventional TPD with fixed system parameters, a novel VMTPD was proposed herein. Dynamics properties of the new VMTPD were studied via simulations and experiments, and the relationship between the volume of water in container and the optimal frequency of vibration reduction was established by using data fitting method. The results show that the optimal frequency of vibration reduction of the proposed VMTPD can be adjusted by changing the volume of water, and a wideband VMTPD can be obtained. |
