Self-adaptive variable-stiffness three-dimensional shock/vibration isolation device
The invention relates to the field of civil engineering and mechanical engineering and the technical field of shock/vibration isolation, and provides a self-adaptive variable-stiffness three-dimensional shock/vibration isolation device. The self-adaptive variable-stiffness three-dimensional shock/vibration isolation device comprises a stress assembly used for receiving impact force and an elastic support. The support carries the stress assembly, among a plurality of cross sections formed by horizontally cutting the support in the direction perpendicular to the impact force, the areas of at least two cross sections are different. According to the self-adaptive variable-stiffness three-dimensional shock/vibration isolation device, different horizontal stiffness and damping forces can be provided in different stress states through the variable cross-section support, the shock insulation/vibration requirements of large-span space structures and middle and high-rise buildings when the large-span space structures and the middle and high-rise buildings encounter different levels of building environment vibration and earthquakes can be met, and then the purpose of self-adaptive variable stiffness is achieved; and a good effect of isolating environment vibration and vertical seismic oscillation can be achieved.
本发明涉及土木工程以及机械工程领域和隔震/振技术领域，提供了一种自适应变刚度三维隔震/振装置，包括用于迎接冲击力的受力组件以及具有弹性的支座，所述支座承载所述受力组件，沿垂直于冲击力的方向平切所述支座形成的多个截面中，至少两个所述截面的面积不相同。本发明通过变截面支座可以在不同受力状态下提供不同的水平刚度和阻尼力，能满足大跨空间结构和中高层建筑在遇到不同等级的建筑环境振动和地震时的隔震/振需求，进而达到自适应变刚度的目的，能起到良好的隔离环境振动和竖向地震动的效果。
