Vertical cavity vibration/vibration isolation and reduction device
The invention discloses a vertical cavity vibration/vibration isolation and reduction device which comprises a carrier plate and a spiral spring, the carrier plate is divided into an upper carrier plate and a lower carrier plate, the spiral spring is arranged between the upper carrier plate and the lower carrier plate, a cavity with an H-shaped longitudinal section is formed in the spiral spring, the cavity is divided into an upper cavity and a lower cavity, the inner side face of the cavity is arranged to be a rough face, and the lower side face of the cavity is arranged to be a concave face. An upper viscoelastic damping block and a lower viscoelastic damping block which are tightly attached to the inner walls of the cavities are correspondingly arranged in the upper cavity and the lower cavity; the viscoelastic damping blocks are correspondingly and fixedly connected with the upper carrier plate and the lower carrier plate; the outer surface of the upper viscoelastic damping block is a rough surface and does not make contact with the bottom of the upper cavity in the static load state, and the lower viscoelastic damping block, the inner wall of the lower cavity and the top of the lower cavity are vulcanized into a whole. The device has the beneficial effects that the viscoelastic damping material is applied to a spring vibration isolation system, effective vibration isolation and vibration reduction are achieved, multi-stage and multi-type energy consumption of friction, tension and compression and shearing is achieved through mechanism design, and the performance stability, robustness and easy implementation of the device are improved.
本发明公开了一种竖向腔体隔减振/震装置，包括载板和螺旋弹簧，载板分为上载板和下载板，螺旋弹簧设置于上载板和下载板之间，螺旋弹簧内设置有纵截面为H型的腔体，腔体分为上腔体和下腔体，腔体内侧面设置为粗糙面，上腔体和下腔体内对应设置有与腔体内壁紧密贴合的上、下部粘弹性阻尼块，上述粘弹性阻尼块对应与上载板和下载板固定连接；上部粘弹性阻尼块外表面设为粗糙面，并且在静载状态下与上腔体底部互不接触，下部粘弹性阻尼块与下腔体内壁以及顶部硫化为一个整体。有益效果：将粘弹性阻尼材料应用于弹簧隔振系统上，实现有效隔减振，通过机构设计实现摩擦、拉压及剪切多阶段、多类型耗能，提升装置的性能稳定性、鲁棒性和易实施性。
