Detailed description of the invention
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is front view of the invention；
Fig. 2 is side view of the invention；
Fig. 3 is top view of the invention；
Fig. 4 is the partial structure side view that driving headstock is connect with driven headstock.
Specific embodiment
Below with reference to attached drawing, the present invention is described in detail, and as shown in Figs 1-4: the present invention provides a kind of vibrations of multiple spot
Dynamic platform simulation underground structure non-uniform method connects system with model casing, driving headstock 1 and driven headstock including multiple alternately connections
2, the quantity of driving headstock and driven headstock is depending on physical simulation engineering, by by spring steel between the driving headstock and driven headstock
Manufactured connector 3 connects, and spring steel avoids the biography because of connection shake table using the material with model experiment case rigidity of the same race
The insufficient rigidity of power structure, and then cause oscillating load that will will appear significant decaying, influence test effect.In the present embodiment, one
It is provided with six connection points altogether, is evenly distributed between driving headstock and the bottom plate of driven headstock and driving headstock is corresponding with driven headstock
Side wall between.Described connector one end and driving headstock or driven headstock are hinged, and the other end detachably connects with driven headstock or driving headstock
It connects, specifically, if one end of connector is hinged with driving headstock, the other end is detachably connected with driven headstock, if connector
One end is detachably connected with driving headstock, then the other end and driven headstock are hinged；In the present embodiment, described connector one end passes through connection
Hook 6 is mounted with the hook 7 for being fixed on driving headstock corresponding position, and the other end is connect by universal spherical joint with driven headstock, in driving headstock
Side wall or the corresponding position of bottom plate are welded with L-type steel plate 8, are provided with hook on two pieces of steel discs of L-type steel plate, different in input
When the seismic wave in direction, using different types of attachment, make the acceleration responsive peak value and dominant frequency and driving headstock of driven headstock
Unanimously, hook is provided on left and right directions and front-rear direction as described in Fig. 1 due to driving headstock, it can be according to need
It wants, is alternately arranged driving headstock and driven headstock along left and right or front-rear direction, to adapt to the seismic wave of different directions.It is described driven
