Abstract
The utility model relates to an automobile low-temperature performance testing laboratory which performs low-temperature environments on automobiles and which has important significance to automobile use in cold regions and traffic pressure alleviation. The automobile low-temperature performance testing laboratory comprises a sealed outer wall in which a roller test stand 4 is installed. The roller test stand is half embedded into the ground in the laboratory. Two refrigeration hosts 1 are disposed on the north wall and the east wall of the sealed outer wall. An engine testing device is arranged at the north of the sealed outer wall and close to the north wall. The south wall of the sealed outer wall is provided with a door 5. The automobile low-temperature performance testing laboratory is used for testing automobile low-temperature performance.
Description
technical field:
the utility model relates to a kind of hardware place equipment of laboratory, particularly the detection use of a kind of house mode of automobile cryogenic property test use.
background technology:
low in north of china in winter environment temperature, be subject to low temperature environment around and the impact of exhausting and denoising energy conversion, the gas outlet of automobile can outwards drip, and this is a very general phenomenon.In the winter in Harbin, outdoor medial temperature can reach-25 ℃ of left and right, and this phenomenon is very general, vehicle flowrate great street is very easy to form the minute surface road that common people often say, attachment coefficient reduction due to road surface, causes braking ability to reduce, and very easily causes traffic hazard.Yet simple outdoor test can not guarantee that temperature constant is constant, can not guarantee that the attachment coefficient on road surface keeps constant, can not meet pavement quality simultaneously and keep constant.These variable factors often cause larger error to experimental result, the effect of impact contrast.Meanwhile, in the situation of low temperature, driver's hang-up when the outdoor automotive ignition being long placed in is also winter.If by experiment, development test phenomenon is reached a conclusion, and then finds out the most effective way and solve this difficult problem, will be that northern Automobile Enterprises improves the market competitiveness.Again because outside air temperature undulatory property is large, test findings can not be accurately and reliably, targetedly.
china is vast in territory, with a varied topography, and weather is various, and special physical geography condition all can produce significant impact to the management of vehicle and performance thereof.Therefore, require automobile will have good regional adaptability.Low-temperature test is a failtests project of just rising.In the world, the low-temperature test of automobile has very important impact for automotive performance aspect.It is the automobile rear very important test event that rolls off the production line of dispatching from the factory.Old brand automobile industry is all furnished with the low temperature test chamber of very well equipped, to facilitate the contrast test of carrying out under low temperature environment, has formulated the standard of international low-temperature test simultaneously.If but only rely on external test result, can not meet Chinese national conditions completely, and cost is huge, can not detect domestic independent brand simultaneously, affected the market competitiveness of domestic car.Yet the environment of outdoor test is limited by the factors such as region season, the construction of state's low temperature test chamber is very necessary still.Low temperature test chamber simulation low temperature state, compares with Han Qu test on the spot, can save manpower. material resources and financial resources, be not subject to extraneous Climatic Effects, and be not subject to seasonal restrictions, environment control accuracy is higher. good stability. reproducible.
to sum up, for the winter of northeast cold, ethanol vapor wet goods fuel is studied at the application performance of cold district, thereby designed low temperature test chamber, carry out the performance evaluation contrast test of car load and engine, for solve automobile cold use and alleviate traffic pressure and have very significance.
utility model content:
the purpose of this utility model is to provide a kind of automobile cryogenic property test laboratory, particularly hardware environment environment division wherein.
the purpose of this utility model is achieved in that
a kind of automobile cryogenic property test laboratory, its composition comprises: sealing outer wall, testing drum platform is housed in described outer wall, described testing drum platform partly embeds laboratory underground, on the adjacent wall in sealing outer wall north side, east side, be provided with two refrigeration host computers, Engine Block Test device is arranged on to described sealing outer wall north side near metope place, and described sealing outer wall southern side metope is provided with door.
described automobile cryogenic property test laboratory, described refrigeration host computer is the outdoor unit of integral wind cooling; Described Engine Block Test device is comprised of with engine automotive engine test bench and test, and described Engine Block Test bottom of device is bolted on the ground that seals outer wall by one group.
beneficial effect:
the utility model can form detect use, the automotive performance test space under test different temperature condition.Probe temperature is stable simultaneously continues, and guarantees automobile cryogenic property measuring accuracy.
of the present utility model simple in structure, convenient test, engine and automotive test stand temperature environment can manual shift, wide accommodation, bus location is reliable.Test performance concentrates in the laboratory of equilibrium temperature simultaneously, and test result is reproducible. and test data is accurately and reliably. and energy consumption is low.
accompanying drawing explanation:
accompanying drawing 1 is structural representation of the present utility model.
embodiment:
embodiment 1:
a kind of automobile cryogenic property test laboratory, its composition comprises: sealing outer wall, testing drum platform 4 is housed in described outer wall, described testing drum platform partly embeds laboratory underground, on the adjacent wall in sealing outer wall north side, east side, be provided with two refrigeration host computers 1, Engine Block Test device is arranged on to described sealing outer wall north side near metope place, and described sealing outer wall southern side metope is provided with 2 road hermatic doors 5.
embodiment 2:
according to the automobile cryogenic property test laboratory described in embodiment 1, described refrigeration host computer is the outdoor unit of integral wind cooling; Described Engine Block Test device is comprised of with engine 2 automotive engine test bench 3 and test, and described Engine Block Test bottom of device is bolted on the ground that seals outer wall by one group.
embodiment 3:
according to the automobile cryogenic property test laboratory described in embodiment 1 or 2, testing drum platform is used for carrying out test pavement simulating, and with the replacement road surface, surface of cylinder, the surface of cylinder rotates with respect to automobile; Testing drum platform is the basic composition part of dynamometer machine, and its structure and performance will directly affect the measuring accuracy of dynamometer machine; During detection, tested automobile driving wheel is supported on cylinder, and driving wheel drives cylinder to rotate, and cylinder is equivalent to movable road surface, the relative motion of simulated automotive between road surface.
engine low temperature test is normally in order to study the low-temperature cool starting performance of engine, and the data such as engine test bench characteristic under low temperature environment; By experiment, obtain the ultimate temperature of engine cold-start; Under low temperature environment, the duty of engine; Warm-up period, looks for the working law of engine in low temperature environment.
