As shown in fig. 1, the seismic mount 10 with a self-test function includes: the vibration isolation support comprises a vibration isolation support body 100, a signal generator 200 and a signal acquisition instrument 300.

The laminated rubber-vibration-isolating unit 130 may be formed by alternately laminating a plurality of layers of steel plates and rubber, wherein each layer of steel plate may be connected with the rubber through vulcanization of the rubber, and the rubber may be common rubber.
It should be noted that the seismic isolation bearing 10 according to the embodiment of the present invention may be used in the field of seismic isolation of a building bridge or instrument vibration isolation, for example, when used in the field of seismic isolation of a building bridge, the seismic isolation bearing may be installed on a seismic isolation layer (not necessarily a bottom layer) of a building and a pier of a bridge. For example, when the method is applied to the field of seismic isolation of building bridges, the first connecting plate 110 and the second connecting plate 120 are connected to a pre-buried plate in a building, a specific installation process is known in the art, and a detailed description of the specific installation process is omitted here to avoid redundancy.
In addition, when the seismic isolation bearing 10 of the embodiment of the present invention is applied specifically, a person skilled in the art may set a specific position and a specific direction according to an actual situation, as shown in fig. 2, the arrangement mode of the first connection 110 being located above and the second connection plate 120 being located below may be adopted; alternatively, the arrangement of the first connection plate 110 on the lower side and the second connection plate 120 on the upper side is not limited in detail.
Alternatively, in an embodiment of the present invention, the first connection plate 110 is provided with a first groove to embed the exciter 400.
It can be understood that, in the embodiment of the present invention, not only the exciter 400 may be directly attached to the first connection plate 110, but also a groove may be provided on the surface of the first connection plate 110, and the exciter 400 may be attached to the groove, so that the signal generator 200 may emit a vibration driving signal to drive the exciter 400 to vibrate.

Optionally, in an embodiment of the present invention, a second groove is provided on the second connection plate 120 to embed the vibration sensor 500.

It can be understood that the seismic isolation bearing 10 of the embodiment of the invention can be suitable for a common laminated rubber seismic isolation bearing without a lead core, can also be suitable for a lead core rubber seismic isolation bearing added with a lead core, and has better applicability and practicability. The lead core provides yield strength and rigidity required under the conditions of energy consumption and static load under the earthquake, the lead core has little deformation due to higher initial rigidity under the action of lower horizontal force, and under the action of the earthquake, the lead core is subjected to yielding, so that the earthquake energy is consumed on one hand, and the rigidity is reduced on the other hand, and the aim of prolonging the structural period is fulfilled.
Further, the vibration isolation support 10 of the embodiment of the invention can realize nondestructive detection of internal damage of the laminated rubber vibration isolation support, and the principle is to perform damage detection by using a vibration-based damage detection technology or an ultrasonic flaw detection technology, wherein the ultrasonic flaw detection principle is the same as the vibration flaw detection principle, but in ultrasonic flaw detection, the vibration exciter is an ultrasonic transducer, and the others are the same as vibration flaw detection. The vibration isolation bearing with the self-detection function will be further explained by the specific embodiment.
As shown in fig. 3, a vibration driving signal is sent by the signal generator to drive the piezoelectric ceramic vibration exciter to vibrate, the vibration signal is transmitted to the piezoelectric ceramic sensor through the first connecting plate, the laminated rubber vibration isolation unit, the lead core and the second connecting plate, and a vibration feedback signal is obtained through the signal acquisition instrument. After damages such as stripping of rubber and a lead core, aging of the rubber, breakage of the lead core and the like in the shock insulation support occur, the physical characteristics of the structure are changed, and signals received by the sensor are different. The damage characteristics of the vibration feedback signals are extracted by processing the vibration feedback signals in a time domain, a frequency domain and a time-frequency signal, so that the target of nondestructive detection of the internal damage of the laminated rubber vibration-isolation support can be realized.
According to the embodiment of the invention, the defect that the working state and the damage condition of the traditional vibration isolation support are difficult to detect is overcome through a vibration detection technology, and the aim of nondestructive detection of the internal damage of the laminated rubber vibration isolation support is realized.
