摘要
采用实验的方法,对宽带波导动力吸振器的吸振效果用多种评价方法进行评价,并将几种方法作比较,进而通过测量安装动力吸振器的结构和安装与动力吸振器同样质量的质量块的结构振动情况对比,证明:螺旋曲梁宽带动力吸振器的吸振效果良好,附加质量对吸振的效果影响不大。
The effects of bandwidth UVA（ dynamic vibration absorber） in experiments are compared utilizing variable estimation methods. Through measuring the vibration characteristics of structure with DVA and with a mass which has the same weight as the DVA, the effects of bandwidth DVA and the influences of additional mass to the structure are concluded. The results show that, the effects of bandwidth DVA whose structure is helix bending beam are quite good, the additional mass influences the absorbing effects little.
