Abstract:Through theoretical force analysis of the wedge locking device, the exact solutions for the pressure of each stage of the locking device were derived, and the influencing laws of the pressure were revealed. The analysis indicates that, owing to the presence of friction, the contact pressure between inclined surfaces of each stage of the wedge locking device gradually decays with the increase in the stage number; consequently, the pressure exerted by the locking device on the side surface of electronic modules or guide channels also decreases accordingly. Meanwhile, a finite-element simulation model of the wedge locking device was constructed, and statics simulation was performed. The force results from simulation calculations show a high degree of agreement with theoretical calculations, effectively verifying the correctness of the force analysis of the wedge locking device. These findings provide theoretical support for the practical application of the wedge locking device and lay a solid foundation for enhancing the reliability and stability of connections in military electronic equipment.
