[0025] Example 2 Testing with the dust road of the present invention
[0026] Dust adhesion is divided into dry adhesion and wet adhesion. It can be selected according to the verification purpose.
[0027] Dry adhesion: The whole vehicle passes through the dust road in a dry state; it passes through the dust road at a constant speed of 30km / h±5km / h.
[0028] Wet adhesion: Before entering the dust road, first pass through the spray road to soak the whole vehicle to facilitate dust adhesion. At the same time, in order not to bring the water in the spray road into the dust and affect the generation of dust, the length of the connecting road between the spray road and the dust road should not be less than 50 meters. The dust road passing speed is 30km / h±5km / h.
[0029] Dry adhesion test and wet adhesion test are completed once each for 1 cycle, and 10 cycles are completed to inspect the whole vehicle. According to different dust adhesion methods, the inspection contents are dif...

Abstract
The invention relates to a whole vehicle road test, in particular to a dust road for a whole vehicle road test and a test method. According to the technical scheme, the dust road for the whole vehicle road test comprises a road and a canopy arranged on the road; the rain shelter comprises a plurality of stand columns and a ceiling. The middle of the road is the highest point and inclines towards the left side and the right side of the road, and the inclination degree is 2% + / -0.5%; a dust layer is arranged on the road surface; deceleration strips and road edges are sequentially arranged on the left side and the right side of the road from inside to outside, and the deceleration strips are arranged along the inner sides of the road edges at intervals; a reflecting safety indication clearance lamp is arranged on the canopy supporting column; drainage grooves are further formed in the outermost edges of the left side and the right side of the road. By adopting the dust road and the test method, the problem of test simulation deviation caused by no solid particle attachment of the sample vehicle in the whole vehicle road test can be solved.
Description
technical field [0001] The invention relates to a road test of a complete vehicle, in particular to a dust road and a test method for the road test of the complete vehicle. Background technique [0002] In the current road test of the automobile industry, in addition to the assessment of the mechanical strength and durability of the vehicle, it is also hoped to simulate and assess some special scenarios during the use of the vehicle. For example, the sand and dust conditions raised when the car is driving in the dry northwest region, mountainous areas with poor road conditions, construction sites, etc., are easy to adhere to all parts of the car. Or directly enter the air filter, engine, fuel snorkel and other parts, which will affect the performance and function of the vehicle. The effect of sand and dust conditions simulation in the vehicle test and the controllability and consistency of the simulation intensity directly affect the direct performance of the vehicle after ...
