The invention relates to a particle damper capable of controlling a line spectrum. The particle damper capable of controlling the line spectrum comprises a hull structural member, wherein a pluralityof raised metal particles are distributed on the inner wall of the hull structural member at intervals; a rubber ring wraps the periphery of each metal particle; the horizontal and vertical spacing distances of each metal particle are equal; the horizontal wall thickness of each rubber ring is consistent to the radius length of each metal particle; and the metal particles are spheres and are casted on the hull structural member. The particle damper capable of controlling the line spectrum provided by the invention realizes effective vibration isolation and is capable of controlling line spectrum components.
本发明涉及一种控制线谱颗粒阻尼器,包括船体构件,所述船体构件的内壁上间隔分布有若干个凸起的金属颗粒,所述每个金属颗粒的外周包裹有橡胶圈;所述每个金属颗粒的横向间隔和竖向间隔距离均相等;所述橡胶圈的横向壁厚与金属颗粒的半径长度一致;所述金属颗粒为球体,并浇铸在船体构件上。本发明有效隔振,并可以控制线谱成分。
