| 摘 要： | 为了满足对声频振动控制的要求,拓宽动力吸振器的吸振频率范围,本文在对直梁宽频带动力吸振器研究的基础上,研究了螺旋曲梁式动力吸振器.研究表明,该吸振器具有更密集的模态,因而具有宽频带的吸振性能.它的变截面形式使得它具有更强的消耗振动能量的能力,数值分析还表明如果设计合理,在0～1000Hz的频率范围内都可以获得较大的吸振量,有望成为噪声与振动控制新的有效手段.

| Abstract: | In order to control the audio frequency vibration and extend the absorbency range of dynamic vibration absorber, based on the study of wide band straight beam vibration absorber, the twist-beam dynamic vibration absorber is studied in this paper. It is proved that it has denser mode than traditional DVA, so it has wide absorbency range. The numeric analysis indicates that it can control vibration from 10Hz to 1000Hz and reduce the vibration obviously. The DVA presented in this paper can be used to control the noise and vibration simultaneously, which provides a new approach to control sound radiation born by structural vibration. |
