摘要
在单质量磁吸振器的基础上提出了双质量磁吸振器的设计方案,并对其减振性能进行了理论和试验研究。正弦扫描和窄带随机振动试验结果表明,平板小阻尼系统在添加双质量磁吸振器后,比单质量磁吸振器振动水平明显减小。
In order to improve the performance of the single magnetic vibration absorber, an application of a dual magnetic vibration absorber made of rare-earth magnets (NdFeB) is proposed in this study. Test results show that for small damping systems, a dual magnetic vibration absorber with a small mass ratio has good performance not only on harmonic excitations but also random ones with narrow frequency band.
