Nonlinear damping device
The invention provides a non-linear damping device. The non-linear damping device comprises a frame, a sliding block, a transverse linear telescopic assembly and a longitudinal linear telescopic piece. A longitudinal sliding rail is arranged on the frame, the sliding block is arranged on the longitudinal sliding rail in a sliding mode, one end of the longitudinal linear telescopic piece is connected with the frame, and the other end of the longitudinal linear telescopic piece is connected with the sliding block. Guide track grooves are symmetrically formed in the positions, on the two sides of the longitudinal sliding rail, of the frame, and transverse linear telescopic assemblies are symmetrically arranged on the two sides of the sliding block in the longitudinal direction; one end of the transverse linear telescopic assembly is connected with the sliding block, and the other end of the transverse linear telescopic assembly is movably arranged in the guide track groove. The guide track groove comprises a first curve groove section and a second curve groove section which are symmetrically arranged in the transverse direction, and track lines of the first curve groove section and the second curve groove section are both quadratic functions. The vibration reduction device has a polynomial rigidity form, has better robustness, and can realize efficient vibration reduction of the structure in a broadband and wide range.
本发明提供一种非线性减振装置，包括框架、滑动块、横向线性伸缩组件和纵向线性伸缩件；所述框架上设有纵向滑轨，滑动块滑动设置于纵向滑轨上，所述纵向线性伸缩件一端连接框架，其另一端连接滑动块；所述框架在纵向滑轨的两侧对称设有导向轨迹槽，所述滑动块在纵向方向的两侧对称设有横向线性伸缩组件；所述横向线性伸缩组件一端连接滑动块，其另一端活动设置于导向轨迹槽中；所述导向轨迹槽包括关于横向方向对称设置的曲线槽段一和曲线槽段二，曲线槽段一和曲线槽段二的轨迹线均为二次函数。本发明的减振装置具有多项式的刚度形式，具有更优的鲁棒性，可实现结构在宽频、宽幅范围内的高效减振。
