Description

A kind of noise reduction test-bed device of fuel tank of vehicle

Technical field

The utility model relates to a kind of fuel tank of vehicle, is specifically related to a kind of fuel tank experimental stand that can noise reduction.

Background technology

There is comparatively ripe technology path and car load strategy in external main engine plants to vehicle fuel machine noise reduction aspect, and solution miscellaneous also appears on the sedan limousine of all kinds of imports again and again.

The research of moving noise is shaken still in the starting stage to fuel oil by domestic a lot of independent brand car load enterprise, but focuses mostly at present in the research and development of low and middle-grade cars, does not cause too many attention. Along with one's own judgment maturation and the development of China Auto Market, Chinese customer will be recognized very soon fuel oil rolling moving noise and set it as one of judgment criteria of complete vehicle quality.

All kinds of scientific research institutions do not have commercioganic driving, and few people drop in this respect energy and go research. The fuel oil manufacturing enterprise of state inside and main engine plants are because participating in car load design and the parts research and development of foreign brand name, to this respect understanding relatively early. But because fuel oil noise relates to very profound theory, most domestic enterprise does not possess this capacity of scientific research interdisciplinary at present, so Development Technology is very slow.

Utility model content

The purpose of this utility model is to provide a kind of noise reduction test-bed device of fuel tank of vehicle, this device practicality, cost are lower, the fuel oil that can detect fuel tank of vehicle shakes moving noise, and then can propose noise that various measures suppress to reduce fuel tank to improve complete vehicle quality and to meet the need of market.

The purpose of this utility model is achieved through the following technical solutions, a kind of noise reduction test-bed device of fuel tank of vehicle, it is characterized in that, described noise reduction test-bed device comprises pedestal, track, slide unit and fuel tank, bottom acoustic board, metal stop bar, start stop switch, the lever switch of stopping; On pedestal, broad ways arranges several bar grooves of stopping, and is provided with along its length track on pedestal; Described slide unit is set on track, and slide unit can slide along track, and described fuel tank is set on slide unit; The metal bar of stopping is arranged on the both sides of described track, the metal bar one end of stopping is movably arranged on and stops on bar groove, the metal bar of stopping can move around on bar groove stopping, the metal bar other end of stopping is fixed on described pedestal, stop bar below of metal arranges bottom acoustic board, and bottom acoustic board is fixed on described pedestal; Start stop switch control slide unit moves and stops; The folding that the lever switch control metal of stopping is stopped bar.

Preferably, described noise reduction test-bed device also comprises rectangle working plate, and described start stop switch, the lever switch of stopping are set on rectangle working plate.

Preferably, described fuel tank is fixed on slide unit by support.

Preferably, the described metal end that bar is positioned on described pedestal of stopping is provided with circular retainer ring.

Compared with prior art, the utlity model has following beneficial effect:

The first, this testing stand can provide desired initial velocity for fuel tank, and certain brake acceleration is provided afterwards, the braking state in simulating driving procedure, simultaneously can measure fuel tank stop motion after fuel oil rock the noise of generation. The product development initial stage, measure by manufacturing exemplar, can judge that the fluid of fuel tank rocks noise level at the product development initial stage, for the design optimization of fuel tank noise control provides foundation.

The second, fuel tank test-bed, as the experiment of parts rank, has reduced cost, has shortened the fuel tank construction cycle, has improved efficiency. This improves Chinese automobile consumption market and has played beyond doubt huge effect for the development that promotes auto industry.

The 3rd, the utility model is a kind of new structure that reduces fuel tank noise of test. Along with the development of auto industry, the vibration and noise problem on automobile receives publicity day by day. The utility model is from actual demand, on the source of noise and bang path, carries out noise reduction process, proposes the fuel tank test-bed of a automobile, and the test of this test-bed is played certain facilitation to the development of auto industry.

Brief description of the drawings

Fig. 1 is the design structure diagram of the noise reduction test-bed structure of a kind of fuel tank of vehicle of the utility model.

In figure: start stop switch 1, metal stop bar 2, track 3, slide unit and fuel tank 4, bottom acoustic board 5, pedestal 6, slide bar groove 7, the lever switch 8 of stopping.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

As shown in Figure 1, a kind of noise reduction test-bed device of fuel tank of vehicle, comprises pedestal 6, track 3, slide unit and fuel tank 4, bottom acoustic board 5, metal stop bar 2, start stop switch 1, the lever switch 8 of stopping.

On pedestal 6, broad ways arranges several bar grooves 7 of stopping, and is provided with along its length track 3 on pedestal 6; Described slide unit is set on track 3, and slide unit can slide along track, and described fuel tank is set on slide unit.

The metal bar 2 of stopping is arranged on the both sides of described track 3, and metal bar 2 one end of stopping are movably arranged on and stop on bar groove 7, and the metal bar 2 of stopping can move around on bar groove 7 stopping, and metal bar 2 other ends of stopping are fixed on described pedestal 6.

Metal stop bar 2 belows arrange bottom acoustic board 5, bottom acoustic board 5 is fixed on described pedestal 6.

Start stop switch 1 is controlled slide unit motion and is stopped; The lever switch 8 of stopping is controlled the folding that metal is stopped bar 2.

Above-mentioned noise reduction test-bed device also comprises rectangle working plate, and left and right, rectangle working plate front arranges described start stop switch 1, the lever switch 8 of stopping.

Fuel tank is fixed on slide unit by support.
