Abstract
The utility model discloses a building block type mechanical motion mechanism for simulating seismic oscillation table array system which relates to a simulating seismic oscillation test apparatus. The building block type mechanical motion mechanism for simulating seismic oscillation table array system includes a plurality of auxiliary oscillation tables which are integrated on the base with the optional position. Each oscillation auxiliary table is assembled with a table top, an exciter, a hinged connecting rod and a base. Both ends of the exciter and the hinged connecting rod are provided with the universal rotating hinges which are connected with the table top and the base. The exciter of the oscillation table and the hinged connecting rod are horizontally or vertically connected with the table top and the exciter and the hinged connecting rod which are connected on the table top can be mutually replaced to guarantee any combined oscillation system with one to six freedom degrees. Because the array system can be moved to the lateral direction, the lateral force is eliminated after the array system is formed as needed. The random span is realized and the oscillation test of random freedom degree of the span value from one freedom degree to six freedom degree is realized. The building block type mechanical motion mechanism for simulating seismic oscillation table array has high flexibility and is convenient to arrange. Compared with the oscillation of the single oscillation table with the same area, the building block type mechanical motion mechanism for simulating seismic oscillation table array system has low investment and notable efficiency.

Embodiment:
Connect and compose the needed simulated earthquake vibration stand table array system of different simulated earthquake vibration tests according to the technical scheme that Fig. 3-Figure 10 provided by the known technology setting.
Brick pattern simulated earthquake vibration stand table array system mechanical motion mechanism, each sub-vibration table surface 9 times is connected to 3 statically determinate structures in the mechanics with vibrator 10 or articulated linkage 11 and base, when a plurality of sub-shaking tables are formed the array, can be only between table top central spot and base, only be connected a vibrator.
Wherein Fig. 4 is that this is that single level is to motion by the general earthquake simulation shaking table of the sub-platform of separate unit appellation of four kinds of component-assembled one-tenth.If articulated linkage 11 is all replaced with vibrator 10, under the driving of control system, can realize the vibration of list platform three-dimensional six degree of freedom.This seed shaking table optionally can have some, to be combined into table array system.
Fig. 5 wherein has only a sub-platform to have articulated linkage of side direction to connect for by the simulated earthquake vibration stand table array system of a plurality of single levels that are combined into of sub-platform shown in Figure 4 to vibration.The chassis of test specimen is linked to be an integral body with each sub-platform table top, can carry out the earthquake simulation test of multispan bridge, pipeline, transmission line of electricity.This combination still can be rotated test.Because vertical support is the double end articulated linkage, side direction can move, thus the vibrator direction a little not parallel can not give test specimen at x to bringing internal force to produce.Partly bring additional external force can for vibrator yet.If test specimen is an elastic body, still can carry out the test of multiple spot various amplitude, can not produce side force, test specimen the elastic deformation force then born by vibrator.
Fig. 6 for the list that is combined into by a plurality of sub-platforms vertically to the simulated earthquake vibration stand table array system of vibration, wherein a terminal board keeps a side direction articulated linkage, horizontal vibrator substitutes with articulated linkage, the horizontal vibrator place of the sub-platform of the other end changes articulated linkage into, the side direction articulated linkage is removed, and horizontal vibrator of all the other sub-platforms and side direction articulated linkage are removed, and vertically the articulated linkage of each sub-platform all replaces with vibrator, can carry out single vertically to vibration test, and can carry out two and rotate test up and down.Model can not produce internal force when having solved vibration in the axial base plate of x connects yet.If test specimen is an elastic body, also can do the multiple spot input exciting of different amplitudes, only be that the elastic force of test specimen is born by vibrator.
Fig. 7 is the simulated earthquake vibration stand table array system of a vertical and horizontal vibration of the slim-lined construction test that is combined into by a plurality of sub-platforms, each sub-platform level to vertical to being vibrator, end one sub-platform keeps articulated linkage of side direction.Can carry out the vibration test of two translations and three rotations.Fig. 8 also changes vibrator into for the one sub-platform of the end among Fig. 7 keeps articulated linkage of side direction, then can carry out the six-freedom degree vibration test of three translations and three rotations.
Fig. 9 is the simulated earthquake vibration stand array pilot system of the square structure be made up of 4 sub-platforms, and the test specimen chassis is in aggregates with four sub-platform mesa shape, realizes the six degree of freedom vibration of three translations and three rotations.The simulated earthquake vibration stand array pilot system that Figure 10 also is made up of 4 sub-platforms, because test specimen chassis and four sub-platform table tops form an integral body, so it is a supporting and excitation that vertical vibrator can be reduced to each sub-platform, realized the six degree of freedom vibration of three translations and three rotations equally.
The utility model is compared with the separate unit shaking table with area, invests lowly, brings notable results.
