Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As Figure 1-4, the utility model high-speed train bogie cabin flow field state testing device and method, wherein, high-speed train bogie cabin flow field state testing device is for gas flowfield state in side-looking bogie cabin, comprise: many try be fixed on skirtboard 2 and end plate 3 madial wall, be arranged on the camera head 5 in bogie cabin, be arranged on bogie side the aerosol producer 6 be communicated with bogie cabin by pipeline out of my cabin, and be arranged on one or more aerosol outlet port 7 at bogie 1 top, the inwall of skirtboard 2 and end plate 3 selects multiple equally distributed test point 4, each test point 4 is connected with examination line, examination line is soft bar, preferred use cloth, silk ribbon etc., for ease of observation, one deck fluorescence coating can be coated with in try.One end of examination line is fixed in test point 4, and the other end hangs down naturally, can along with air motion; For avoiding try to be mutually wound around, test point 4 is set greater than try double length.
The deflection state of try refers to: try blows the lower yawing moment relatively naturally drooping state at air-flow, can indicate gas and flow forward or backward; The motion state of smog refers to: smog is from entering bogie cabin in this certain time left from aerosol outlet port, the movement locus of smog, and the image that this movement locus is taken by different time points or video carry out process and obtain.
Because aerosol producer 6 volume is comparatively large, be placed in bogie cabin and can produce larger impact to the motion of air-flow in bogie cabin, affect measurement data; Therefore aerosol producer 6 is arranged on bogie out of my cabin, and is communicated with bogie cabin by pipeline.Aerosol producer 6 can spray band the colorful one smog, and after smog enters bogie cabin by pipeline, along with in cabin, gas flows together, and the aerosol outlet port 7 eventually through bogie 1 top is discharged.
Camera head 5 is free to rotate, is convenient to adjustment direction, obtains clearly, try waves or the video of smoke flow or photo, for analyzing the distribution of bogie 1 flow field.Camera head 5 is provided with light filling unit, in bogie cabin dark, when cannot obtain clear photograph, open light filling unit, for camera head 5 supplements light.Camera head 5 can select suitable position to be fixed as the case may be, to obtain best shooting angle.
The utility model also disclosed a kind of utilize said apparatus, the state of bogie cabin flow field is tested, high-speed train bogie cabin flow field state test method, comprise the following steps:
S1: under train operation state, opens camera head 5, takes the yawing moment of each test point 4 place try on end plate 3 and skirtboard 2 inwall; Yawing moment can represent the overall flow direction of test point 4 place air-flow, such as forward or backward.
S2: according to the shooting results of step S1, the motion state of analytical test point 4 place air-flow; Namely by the yawing moment of each test point 4 place try in photo or video, analyze and obtain the end plate 3 of bogie 1 and the gas flow direction at skirtboard 2 inwall place.
S3: open aerosol producer 6 and camera head 5, the smog of ejection enters bogie cabin by pipeline, and smog moves along with the air-flow in bogie cabin, discharges eventually through aerosol outlet port 7; At smog in the process in bogie cabin, the motion state of camera head 5 captured in real-time smog;
S4: the smog photographed according to step S3, in the motion state of different time points, is analyzed and obtained the movement locus of smog in bogie cabin, obtains the flow field state in bogie cabin.
Consider Changes in weather and light at the night factor such as poor, in the process that step S1 and S3 carries out, light filling unit detects the light intensity in bogie cabin in real time, according to the light conditions in bogie 1, automatic unlatching or closedown, for camera head 5 supplements light, to get video or photo the most clearly, improve the accuracy of test.
During test, step S1 and S3 can be selected simultaneously to carry out, flow field state complete in bogie cabin can be recorded; If necessary, also can independently perform step S1 or step S3, namely only measure one of them, such as obstructed smog, only observe the deflection situation of try, measure the flowing gas state at skirtboard 2 and end plate 3 inwall place.
As can be seen from the above embodiments, the utility model by arranging try and camera head 5 in bogie cabin, and passes into colored smoke by pipeline in bogie cabin, can observe directly the flow process of gas in bogie cabin; By the motion state of camera head 5 real time record try and smog, real flow field state in bogie cabin can be obtained; Due to test be bullet train under steam bogie cabin in carry out, all data are all that Real-time Collection obtains, and without the need to simplifying bogie 1, analog computation, by simple process, just can obtain the true flow field state in bogie cabin.Try can be the common material such as cloth, silk ribbon, for ease of observing, can apply layer of fluorescent powder in try, forms fluorescence coating, simple to operate; Try is directly bonded on bogie 1 inwall, and proving installation structure is simple, and cost of manufacture is lower; The more generous aerosol producer 6 of volume is arranged on bogie out of my cabin, avoids impacting the flow field in bogie cabin.A whole set of test structure is simple, and method of testing easily operates, and only need open aerosol producer 6, then the result photographed be processed, just can obtain the state of bogie cabin flow field.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and replacement, these improve and replace and also should be considered as protection domain of the present utility model.
