Specific embodiment
The present invention is explained in detail with reference to the accompanying drawing:
The utility model provides a kind of polyaniline automatic temperature control system, as shown in Figure 1, one vertical
The fixing end of the linear actuator 4 of setting is fixedly connected with the horizontal fixed frame of top, and linear actuator 4 makees moved end by one
A clamp system 5 is fixedly connected with the piston rod top end of the damper 7 to be tested of lower section, the oil storage cylinder lower end surface of damper 7
Hinged with firm banking 12, firm banking 12 is fixed on No. 13 bottom of water tank, and 14 sets of water ring of a circular ring shape are in damper 7
Oil storage cylinder in the middle part of except, the inner ring of water ring 14 is provided with multiple hole for water sprayings, and hole for water spraying is aligned in the middle part of the oil storage cylinder of damper 7,
Water ring 14 is connected to one end of a water inlet pipe 8, the other end of water inlet pipe 8 protrude into No. 2 water tanks 11 and in No. 2 water tanks 11
The water outlet of constant flow water pump 13 connects, and No. 1 water tank 3 and No. 2 water tank 11 is connected to by two return pipes 9, temperature sensor 6
Measuring head is attached on the guider of damper 7, the guide groove for having two column to be vertically arranged on a support 2 being vertically arranged, and two
The front end of a guide rod 1 is fixedly connected with a free bearing 15, and free bearing 15 and clamp system 5 are hinged, the front end of each guide rod 1 with
One slide 16 is hinged, and slide 16 is embedded in the corresponding guide groove of support 2 and can slide up and down in guide groove, temperature sensing
Device 6 and constant flow water pump 13 are connect by harness with a temperature control unit 10, and temperature control unit 10 is fixedly installed No. 2
Outside the cabinet of water tank 11.
The working principle of the utility model is as follows:
The piston rod top end of damper 7 is connected with clamp system 5, in the middle part of the oil storage cylinder of damper 7 and No. 13 bottom of water tank
Firm banking 12 it is hinged, clamp system 5 is connected with linear actuator 4 as moved end, therefore the vertical displacement of damper 7 is equal to
The vertical displacement of linear actuator 4；Guide rod 1 is connect with clamping mechanism 5 by pin, it is thus ensured that the movement of damper 7
Track is vertical direction；Damper generates big calorimetric in up-and-down motion, needs cooling water to be cooled down, cooling temperature
Should be corresponding with real vehicle damper temperature, temperature is excessively high to cause damper abnormal damage, and temperature is too low to be not achieved verification the verifying results；Cause
, by the measuring head of 7 temperature highest point of damper, that is, damper 7 guider position mounting temperature sensor 6, temperature control is single for this
Member 10 monitor in real time temperature sensor 6 acquire temperature, set temperature control unit controlled at T DEG C, work as temperature sensing
The temperature signal > (T+1) DEG C that device 6 acquires, temperature control unit 10 power on the quantitative water pump 13 of control and work to water inlet pipe 8
Interior water filling, aperture is machined at 8 end annulus of water inlet pipe, and cooling water is sprayed to damper 7 from aperture to make its temperature drop
Low, when signal < (T-1) DEG C temperature control unit 10 that temperature sensor 6 acquires disconnects power supply, quantitative water pump 13 stops working
It is no longer filled the water into water inlet pipe 8, cooling system break-off, with the continuous variation of damper temperature, temperature control unit 10
Repetitive control quantifies water pump 13 and switches between connecting and disconnecting, in cycles until completing bench test；Water tank 1 and water tank two
It is connected between 11 by return pipe 9, when the liquid level of water tank one is higher than water tank two, cooling water is flowed by return pipe 9 by water tank one
Water tank two, therefore two water tank levels remain basically stable always, cooling water, which can be recycled, to be overflowed by water tank.
