The disc 10 is mounted perpendicular to the laser bands of the laser transmitter 6 and laser receiver 7 so that the simulated precipitation particles attached to the disc can enter the laser bands perpendicularly.
In this embodiment, because the rotating speed of the disk 10 can be obtained by the rotating speed sensor 15 in cooperation with the controller 8, the distance between the simulated precipitation particle patches 12 with different radii and sizes and the center of the disk 10 can also be measured, so that the linear speed of each simulated precipitation particle patch 12 can be calculated when the disk 10 rotates, and the linear speed of the simulated precipitation particle patches 12 is not changed when the disk 10 performs uniform circular motion. The speed of the rain drops passing through the laser band can be regarded as the falling speed of the precipitation rain particles, and the falling speed can be obtained by the laser transmitter 6 and the laser receiver 7 in cooperation with the controller 8. The descending speed and the linear speed of the simulated precipitation particle patch 12 can be used as a comparison value for comparison.

Therefore, the general glass disc material can not meet the experimental requirements, so the selected material should be as uniform as possible in the aspect of working, and too large impurities can not be in the disc. Therefore, the utility model discloses the disc of quartz glass material has been selected.
