Telescoping cylinder 1 and electric expansion cylinder 2 12 move, while RF transmitter 5 is opened, red when crossbeam 9 moves back and forth once
Outside line will be blocked once by sliding sleeve 14, and at this moment infrared receiver 8 will not temporarily receive signal, can thus pass through electricity
Brain calculates the number of crossbeam up and down motion, also it is known that the number that automobile rear case is opened and closed, after automobile
The folding of lid, car rear cover hinge can be subject to the stress of alternation, after fatigue occurs for hinge, the metal layer of the outer surface of hinge axis
Spot corrosion can occur, i.e. localized metallic particle peels off, and causes stress to change, and the stress of hinge axis is by pressure sensor 25
After receiving, computer is passed to, after the pressure that pressure sensor 25 is experienced reaches certain value, computer control electric expansion cylinder one
10 and electric expansion cylinder 2 12 close, statistics is finally reached the number of fatigue, and draws out S-N curves, completes to after automobile
Cover hinge testing fatigue.
