Dynamic vibration absorption type damper
The invention belongs to the technical field of vibration and noise reduction, and particularly relates to a dynamic vibration absorption type damper which comprises a resonance structural part, at least one vibration absorption structural part and an elastic damping body used for filling a gap between a base plate and a resonance plate. The resonance structural member comprises a rigid supporting member, and a substrate and a resonance plate which are rigidly fixed on two sides of the rigid supporting member respectively; one end of the vibration absorption structural part is rigidly connected with the rigid supporting part to form a cantilever type structure, the rigidity and the mass of the vibration absorption structural part change in a gradient mode in the length direction of the vibration absorption structural part, and the part, with small rigidity and mass, of the vibration absorption structural part deforms more easily, so that the overall vibration absorption mass is increased; the problem that in the prior art, due to local deformation of a cantilever beam with the single rigidity design, the mass of participating in vibration absorption is insufficient is solved, the vibration absorption frequency band of the dynamic vibration absorption type damper is widened, and then the vibration reduction and noise reduction requirements of different track lines are met.
本发明属于减振降噪技术领域，具体是涉及到一种动力吸振式阻尼器，包括共振结构件、至少一个吸振结构件以及用于填充基板与共振板之间空隙的弹性阻尼体，共振结构件包括刚性支撑件以及分别刚性固定于刚性支撑件两侧的基板和共振板；吸振结构件的一端与刚性支撑件刚性连接形成悬臂式结构，吸振结构件沿着自身长度方向刚度和质量梯度变化，该吸振结构件刚度和质量较小部分更易变形，从而增加整体吸振质量，避免现有技术中的单一刚度设计的悬臂梁出现的因局部变形导致参与吸振质量不足的问题，拓宽了该动力吸振式阻尼器的吸振频带，进而满足不同轨道线路的减振降噪要求。
