Rigidity and damping anisotropic four-degree-of-freedom nonlinear energy trap vibration reduction system
The invention discloses a rigidity and damping anisotropic four-degree-of-freedom nonlinear energy trap vibration reduction system which comprises a bearing face, a supporting column, a mass block, a support and at least three groups of springs and dampers, the support is arranged on the bearing face and supports the mass block, one end of each group of spring and damper is connected with the mass block, and the other end of each group of spring and damper is connected with the other end of each group of spring and damper. The extension line of the central axis of each group of springs and damper does not pass through the mass center of the mass block, so that the elastic restoring force of each group of springs is far away from the mass center of the mass block to form a force arm, and then the torque opposite to the torque direction of the mass block is generated. The change of the deflection angle of the mass block can be inhibited, the optimal tuning of three-way translation and torsional frequency is realized by configuring different horizontal and vertical spring rigidities and dampers, the non-linear change of the rigidity is caused by the increase of the stroke and the change of the included angle of the spring system in the movement process, and the multi-mode transient resonance capture is realized.
本发明公开了一种刚度和阻尼各向异性的四自由度非线性能量阱减振系统，包括支承面、支撑柱、质量块、支座和至少三组弹簧和阻尼器，支座设置在支承面上，支座支承质量块，每组弹簧和阻尼器的其中一端与质量块连接，另一端与支撑柱连接，每组弹簧和阻尼器中轴线的延长线不通过质量块的质心，使得每组弹簧的弹性回复力远离质量块的质心形成力臂，进而产生与质量块扭矩方向相反的力矩，各组弹簧和阻尼器排布为旋风状，可抑制质量块偏转角度的变化，并通过配置不同水平向及竖向弹簧刚度和阻尼，实现三向平动及扭转频率最优调谐，且运动过程中弹簧系统随行程的增大，夹角变化导致刚度的非线性变化，实现多模态瞬态共振捕捉。
