Positive and negative stiffness parallel vibration isolation device based on cosine curved beam and vibration isolation system
The invention relates to the technical field of vibration isolation devices, in particular to a positive and negative stiffness parallel vibration isolation device based on a cosine curved beam, comprising: a laminated rubber support comprising an upper connecting plate and a lower connecting plate, a rubber layer and a steel plate layer arranged between the upper connecting plate and the lower connecting plate and located at the center of the upper connecting plate and the lower connecting plate; the fixing structures are arranged on the upper connecting plate and the lower connecting plate and are arranged on the peripheries of the rubber layer and the steel plate layer in parallel; the plurality of laminated cosine curved beams are arranged on the fixing structure, joints are arranged on the laminated cosine curved beams, and the joints are connected with the upper connecting plate; the limiting column is arranged on the lower connecting plate and located at the bottom of the laminated cosine curved beam. The positive and negative stiffness parallel vibration isolation device based on the cosine curved beams is simple in structure, the laminated cosine curved beams are arranged on the periphery of the laminated rubber support in parallel, and the vertical vibration isolation capacity is improved on the basis that the horizontal vibration isolation performance is not affected.
本发明涉及隔振装置技术领域，具体涉及一种基于余弦形曲梁的正负刚度并联隔振装置，包括：叠层橡胶支座，包括上连接板和下连接板，上连接板和下连接板之间设有橡胶层和钢板层，且位于上连接板和下连接板的中心；固定结构，设于上连接板和下连接板上，且并联设于橡胶层和钢板层的外周；叠层余弦曲梁，具有多片，设于固定结构上，叠层余弦曲梁上设有接头，接头与上连接板连接；限位柱，设于下连接板上，限位柱位于叠层余弦曲梁的底部。该基于余弦形曲梁的正负刚度并联隔振装置的结构简单，且通过在叠层橡胶支座的外周并联设置叠层余弦曲梁，在不影响水平隔震性能的基础上，提高竖向隔振能力。
