适于风机叶片的球型液体减振装置及安装方法

适于风机叶片的球型液体减振装置及安装方法，包括球型质量块，回型固定板，形状记忆合金弹簧，组合件和纤维绳。通过采用超高分子量聚乙烯纤维绳在风机叶片内部由上而下串联3个直径依次增大的球型质量块，每个球型质量块四周均通过形状记忆合金弹簧固定于风机叶片内侧设计的回型固定板上，并在球型质量块中装1/2高密度液体和1/2全碳气凝胶。通过叶片振动带动球型质量块从上到下依次振动，产生与外部激励反向的作用力来减小主结构的振动，同时在球型质量块振动时，壳内的液体由于惯性力的作用，压缩并推动高弹性全碳气凝胶绕球心转动，使球型质量块的重心总移向与叶片振动相反的方向，增大了与外部激励反向的作用力，提高了减振效果。 The invention relates to a spherical liquid vibration reduction device suitable for a fan blade and an installation method thereof. The spherical liquid vibration reduction device comprises sphericalmass blocks, concentric-square-shaped fixing plates, shape memory alloy springs, combined parts and fiber ropes; the ultra-high molecular weight polyethylene fiber ropes are connected in series with the three spherical mass blocks which are sequentially increased in diameter from top to bottom inside the fan blade, the periphery of each spherical mass block is fixed on each concentric-square-shaped fixing plate designed on the inner side of the fan blade through one shape memory alloy spring, and one-half of the high dens
