The embodiment of test method：
A kind of test method using testing stand, which is characterized in that include the following steps：
The first step：Testpieces is placed, filming apparatus is adjusted.By testpieces clamping in 30 groove of testpieces fixing device,
Recycling box 3 is installed, the front and back sliding in Adjustment Tests cabin and elevating mechanism 10 adjust recycling box position, and regulating fender 33 highly makes
Accelerate nozzle into 35 face of sand hole.Incident angle is set by adjusting the hang plate 31 of crescent moon clamp 29；It opens and adjusts height
Shooting picture is observed in 1 position of fast video camera 7 and LED light source, adjusts shooting of 21 angle of plane mirror in front of testpieces
Region is in visual field center.
Second step：Place sand dust.Experiment sand dust is positioned in supporting body groove 41, mobile sliding block 40 keeps flat supporting body
In in main pipeline 42, it is then turned off sliding block 40.
Third walks：Gas is released stress, high-speed flow accelerates sand dust to predetermined speed, completes collision reaction experiment.It opens
Gas cylinder 15 opens solenoid valve 11 when air accumulator 12 reaches certain pressure, and supporting body sprays to testpieces through pipeline acceleration,
Aperture is struck in nozzle supporting body to pop up from notch above supporting body separator 37, sand dust continues high speed and sprays to testpieces, complete
At collision reaction process.
4th step：It records sand dust collision reaction experiment process and collects sand dust clast.High-speed camera 7 is opening solenoid valve
Its shooting is triggered while 11, records incidence rate, ball rebound velocity and the rebound direction of sand dust and entire collision reaction mistake
The phenomenon that journey generates.Experimental cabin 2 is adjusted to upright position by the hang plate 31 of adjustment crescent moon clamp 29, is opened baffle 33, is removed
Recycling box 3, the sand dust in collection box, then prevent sand dust from remaining with the sand dust in soft brush clearing and retrieving box.With height after collection
Compressed gas gun, which sprays, removes remaining small sand dust particle inside recycling box and experimental cabin.In the step, it is vertical first to adjust experimental cabin 2
Straight position makes natural and graceful in recycling box 3 under sand dust nature.Experiment sand dust pattern irregularly causes its rebound to be that three dimensions rebounds,
Sand dust reflection direction differs；Testpieces is installed on after can guarantee sand dust collision reaction inside experimental cabin 2, no matter reflection direction such as
What, sand dust and its clast can stay in experimental cabin 2.3 top surface area of recycling box is slightly larger than 2 base area of experimental cabin to ensure sand
Dirt smoothly falls.3 each wall surface of recycling box posts smooth antistatic film, and sand dust can be prevented to be attracted to 3 inner wall of recycling box.It removes
Recycling box 3 collects sand dust and pours into the test parameters such as labelled record incident angle and speed in hermetic bag.After collection
Being sprayed with high pressure air rifle prevents subtle broken sand dust residual and influences recovering effect next time inside recycling box 3 and experimental cabin 2.
