Description
Technical Field
The invention relates to the technical field of building structure and equipment vibration isolation, in particular to an anti-collision self-resetting two-dimensional vibration isolation support.
Background
The two major seismic zones at China are between the European and Pacific seismic zones. Historically, strong earthquakes of more than 6 levels have occurred many times in Yangtze river delta and Zhujiang delta, and in the Jinjin ring Bohai sea region, more than 7 levels of major earthquakes have occurred on average every 44 years in nearly 300 years. Along with the acceleration of the urban process, a great number of national wealths are rapidly concentrated to cities and urban cluster areas. The earthquake is that the stratum is in a complex stress state, when the earth stress exceeds the limit strength of the stratum at a certain place along with the continuous change of the earth crust, the stratum is suddenly broken and dislocated, so that vibration is caused, the vibration is transmitted to the ground surface in the form of elastic waves, an object with certain mass near the ground surface is caused to generate inertia force, and when the earthquake resistance of the object against the inertia effect is insufficient, the object is damaged. The damage to the object is more serious when the excellent period of the local vibration is relatively close to the self-vibration period of the object. The self-vibration period of the object can be obviously changed by arranging a certain vibration isolation device on the object, so that the excellent period of the earthquake is avoided, the inertia force acting on the object is obviously reduced, the damage of the object under the action of the earthquake is reduced, and the safety of the object under the earthquake is improved.
The vibration isolation technology essentially prolongs the self-vibration period of the structure by reducing the rigidity of the vibration isolation layer, so the rigidity of the vibration isolation layer is generally smaller, and under the action of wind load, crowd load and other loads, larger deformation and even serious damage can occur, so that the application of the vibration isolation technology is limited. Analysis of the time scale efficiency of the seismic isolation technique has found that in practice it is only a brief time of seismic action that is truly active for common seismic isolation techniques, and more time is inactive or even counter-active. Therefore, the ideal vibration isolation technology is not operated at ordinary times, and only when the earthquake is temporarily operated, the earthquake is ended and then the operation is stopped. The earthquake short-time prediction and earthquake early warning technology brings application space for the application of the technology, and at the present stage, the development of the earthquake short-time prediction technology encounters great difficulty, but the earthquake early warning technology is vigorously developed, when the earthquake happens, the earthquake early warning technology can fight for valuable but short time for earthquake fortification by utilizing the principle that the light speed is faster than the earthquake wave speed, and the short time makes the improvement of the traditional earthquake isolation technology possible.
In addition, in many cases, since two buildings or two devices are closely spaced, adjacent sides collide with two objects due to vibration, and in many cases, such adjacent sides cannot be allowed to collide, so deformation of the shock insulation support needs to be limited, and particularly for objects moving at high speed like high speed trains, the shock insulation efficiency cannot be reduced due to collision between two trains caused by the existence of the shock insulation support. In addition, the shock-insulating supports also have residual plastic deformations under the effect of strong shocks, which affect the normal use of the structure or the equipment, for example, trains can be difficult to get into station if they have horizontal lateral residual deformations, which also lead to a risk of collisions.
