Description
Technical field
The present invention relates to teaching simulating device, and in particular to a kind of apparatus for demonstrating of simulant building thing shock insulation.
Background technology
Earthquake be earth interior occur drastically rupture caused by seismic wave, cause showing for ground vibration within the specific limits
As earthquake is a kind of huge natural calamity of destructive power, can result in great Loss of Life and property, is effectively arranged if taking
Apply, reduce the dynamic response of structure caused by earthquake motion, can effectively mitigate the structural damage of earthquake zone, it is anti-to reduce structure
The a large amount of expenses shaken and put into, reduce Loss of Life and property.Therefore, it is that an important structure mitigation is arranged to build vibration isolation damping
Apply.Damping modes for now mainly have：Rubber support shock insulation, pendulum bearing shock insulation, roly-poly type Isolating Building, resistance
Buddhist nun's device, energy-dissipating support etc., building foundation vibration isolation are an effective glissandoes.Often isolation measure is said in teaching
Solution, current teaching science popularization mode is usually the approach such as teacher's instruction, books written propaganda poster, and technical term is more, without on the spot
Investigation experience, material object was not met, and understood difficulty of getting up, caused to the understanding shortcoming to seismic isolation technology.
The content of the invention
To solve above technical problem, the present invention provides a kind of apparatus for demonstrating of simulant building thing shock insulation.
Technical scheme is as follows：A kind of apparatus for demonstrating of simulant building thing shock insulation, its key are：Including vibrations base and set
Put the building model on the vibrations base；
