Abstract

Aiming at the failure of instant open after close of CT20 type high-power spring mechanism

the authors describe the structure of the CT20 type high-power spring mechanism and the principle of maintaining closing-state

and analyzes various factors inducing the instant open after close failure.Disassembly analysis of failed mechanisms is conducted.Subsequently

tests demonstrate that the instant open after close failure of the CT20 type high-power spring mechanism is eliminated by controlling the factors mentioned.
