Description
Technical field
The utility model relates to a kind of shaking table, particularly relates to a kind of electromagnetic exciting shaking table.
Background technology
When elastomeric material is used as flexible member, its stiffness coefficient changes because frequency of operation is different.Therefore, the metal rubber piece in automobile absorber have Static stiffness and dynamic stiffness point.Adopt electro-hydraulic servo fatigue test board to carry out automobile absorber metalwork dynamic stiffness in prior art to measure, the upper limit of its testing table available frequency range, vibration displacement is very little, causes measuring accuracy lower, and its price is higher always.
Summary of the invention
The technical problems to be solved in the utility model is: adopt electro-hydraulic servo fatigue test board to carry out automobile absorber metalwork dynamic stiffness in prior art always and measure, the upper limit of its testing table available frequency range, vibration displacement is very little, cause measuring accuracy lower, and its price is higher, provide a kind of electromagnetic exciting shaking table.
In order to overcome the defect existed in background technology, the utility model solves the technical scheme that its technical matters adopts: this electromagnetic exciting shaking table comprises base, electromagnet winding is provided with in described base, described base is provided with the ferromagnetic boots of electromagnetism, the top of the ferromagnetic boots of electromagnetism is provided with electromagnet armature, electromagnet armature connects the two ends of base by spring, is provided with speed pickup between electromagnet armature and the connection of base.
According to another embodiment of the invention, described base is comprised further concavely.
According to another embodiment of the invention, the top that the ferromagnetic boots of described electromagnetism are placed in electromagnet winding is comprised further.
The beneficial effects of the utility model are: this electromagnetic exciting shaking table solves the low problem of measuring accuracy, and its structure is simply small and exquisite, and cost is low, and convenient mobile, working effect is high.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Wherein: 1, electromagnet winding, 2, the ferromagnetic boots of electromagnetism, 3, electromagnet armature, 4, spring, 5, base, 6, speed pickup.
Embodiment
Fig. 1 is structural representation of the present utility model, figure comprises base 5, electromagnet winding 1 is provided with in described base 5, described base 5 is provided with the ferromagnetic boots 2 of electromagnetism, the top of the ferromagnetic boots 2 of electromagnetism is provided with electromagnet armature 3, and electromagnet armature 3 connects the two ends of base 5 by spring 4, is provided with speed pickup 6 between the connection of electromagnet armature 3 and base 5, concavely, the ferromagnetic boots 2 of electromagnetism are placed in the top of electromagnet winding 1 to base 5.
Adopt the 50Hz power frequency of electrical network to power directly to electromagnet winding 1, the resonator system that variable-frequency power sources forms fixed frequency exciting can be replaced.One-piece construction is simple and cost is lower, and one-piece construction produces vibration by electromagnetic induction, and when 50Hz powers, can produce the exciting force of 100Hz in electromagnet, easy to operate, easily movement, work efficiency is high.
