Vibration table is a kind of equipment that product or parts is carried out the vibration simulation test, can evaluate the anti-seismic performance of a product by such test, for examining this product quality that rational basis is provided, therefore be widely used in industries such as space flight, aviation, boats and ships, automobile, electronics, communication, household electrical appliances and instrument and meter.
Electric vibration testing bench utilizes the electric and magnetic oscillation principle design, and its structure mainly is made up of stage body, magnetic cylinder, field copper, moving-coil, Guiding wheel structure and air spring etc.Because the heating easily at work of field copper and moving coil winding in order to guarantee system's proper motion, is furnished with cooling system specially in the electronic testing table.Cooling system has air-cooled and water-cooled dual mode, generally speaking, when testing table thrust when 30kN is following, heating is very not outstanding with contradiction between the heat radiation, cools off for simplified structure adopts pressure cold wind mode usually.In electric vibrating stage body design in the past, one group of cooling air channel is often only established in air blast cooling, and the air channel is located in the stage body, simultaneously field copper and moving coil winding is cooled off, and air outlet is located at the stage body bottom and adopts blower fan to aspirate in the air outlet negative pressure.Thrust is below 10kN, and air inlet is located at the stage body upper side, and thrust is at 10～30kN, and air inlet is located at the position of stage body middle part near field copper.When thrust reaches 50kN or when above, because working current is bigger, be that stage body field copper consumed power is about 20～30kVA, the moving coil winding consumed power is about 15～20kVA, heating is more outstanding with the contradiction of heat radiation, and adopting traditional cooling air channel design this moment is the heat dissipation problem that can not solve winding and stage body well.Abroad, generally adopt Water Cooling Technology to solve the heat dissipation problem of winding and stage body for the high thrust testing table, this measure effect is better, but complex structure, the trouble spot is many, and the cost of care and maintenance is higher.
The purpose of this utility model provides and a kind ofly can adapt to high thrust, and under the air blast cooling condition radiating effect dual cooling air flues structure preferably.
Summary of the invention
For achieving the above object, the technical solution adopted in the utility model is: a kind of dual cooling air flues structure, on stage body, design two air channels respectively, one of them air channel is through field copper, and another air channel is through moving coil winding, the air inlet in two air channels apart arrangement on stage body, air outlet is joined in the stage body bottom, and leads to negative-pressure air fan.
Related content and change interpretation in the technique scheme are as follows:
1, in the such scheme, described " air inlet in two air channels apart arrangement on stage body " can have following two kinds of forms:
(1), two air inlets are arranged up and down at the platform sidepiece.
(2), two air inlets are in the circumferential alternative arrangement in platform sidepiece edge.
2, in the such scheme, more appropriate for the allocation proportion that makes cooling air quantity in two air channels, the air inlet of moving coil winding is 1: 2.5～3.5 with the air-admitting surface of field copper ratio, is the best with 1: 3 wherein.
The utility model principle of work is: design two air channels respectively at moving coil winding and field copper, one of them air channel mainly provides cooling air to moving coil winding, and another air channel mainly provides the field copper cooling air quantity, the air inlet branch in two air channels is arranged, air outlet is connected in parallel, and is attempted by on the negative-pressure air fan.Like this, excitation and moving-coil can both well be cooled off, and have guaranteed the working properly of whole test system.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, the main effect of the utility model: field copper and moving coil winding and stage body rapid heat dissipation, radiating effect is obvious, to the stage body particularly suitable of the electric vibrating system of high thrust more than 5 tons.
2, the utility model is applicable to the high thrust wind-cooling heat dissipating, and simple in structure with respect to water-cooling, cost is low, and is easy to use.
3, the utility model reliable operation, according to such design, the continuous at full capacity operate as normal of the stage body of electric vibration testing bench reached international, advanced international level more than 6 hours through test.
