5、eir state of the rotating speed is higher than speeding strength test to determine the safety and reliability of the clutch disc. For example, santana clutch disc assembly and driven plate total chengdu in ordinary tempe

6、rature requirements in a = rad/s2 acceleration of 50 acc to 12 000 r/min, and platen assembly also requires in high temperature (250 ℃) at a = rad/s2 acceleration of 50 acc to 10 000 r/min without fracture. These tests r

15、side trigger coil rotor set, as the rotor fly crack, debris flying out of line, met trigger trigger circuit triggered by high speed camera shutter open, took a damage the image of the rotor moment. Obviously this design

16、requirements must have taken the camera very high speed. For example the clutch assembly destruction speed than 10 000 r/min, the linear velocity in the 200 m/s above, if want to take clear debris flying out of the insta

17、ntaneous movement condition when, captured fragments of the distance from the 2 mm moving images. So, the camera at least should have t = 2 mm / (200 m/s) = 1 x 10-5 s shooting speed, for ordinary camera it is clearly th

18、e deficits.In order to solve this problem, we developed a common cameras with the high-speed photography in the technology, with the clutch high-speed strength test machine, took the clutch assembly destruction of photog
