摘要：Aiming at the locking problem of the mechanism in face-to-face contact, a kind of parallel mechanical locking device is designed, which can make the locked surface self-locking even when the locking hydraulic system fails, thus ensuring the safety and reliability of the locked mechanism. Through theoretical analysis and dynamic simulation of ADAMS software, the self-locking function of the device is verified and the self-locking Angle is calculated. Meanwhile, considering that the locking device may act as a "resonator" and cause secondary excitation to the locked device, which affects the vibration characteristics of the locked system, the mode analysis of the locking device is done by using ABAQUS software, and the feasibility of the locking device for the locked mechanism excited by low frequency is proved.
