Description
Technical field
The utility model relates to a kind of test unit, relates in particular to a kind of test unit of automobile oscillator.
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 has dividing of quiet rigidity and dynamic stiffness.In prior art, adopt electro-hydraulic servo fatigue test board to carry out automobile absorber metalwork dynamic stiffness always and 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.
Summary of the invention
The technical problems to be solved in the utility model is: in prior art, adopt electro-hydraulic servo fatigue test board to carry out automobile absorber metalwork dynamic stiffness 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 test unit of automobile oscillator.
In order to overcome the defect existing in background technology, the utility model solves the technical scheme that its technical matters adopts: the test unit of this automobile oscillator comprises fuselage ring, bottom in described fuselage ring is provided with hydraulic pressure device, the top of described hydraulic pressure device is provided with electromagnet, the top of electromagnet is provided with lower table, the both sides of described lower table are provided with principal earthquake spring, and the top in fuselage ring is provided with upper table and power sensor.
According to another embodiment of the invention, further comprise in described electromagnet and be provided with AC excitation coil, the both sides of electromagnet are provided with DC magnetizing coil.
The beneficial effects of the utility model are: the test unit of this automobile oscillator has increased sensor and hydraulic amplifier device, and loading force and the frequency range of this structure structure are wide, so amplitude range is also wider, can meet the test of most of automobile absorbers.
Accompanying drawing explanation
