Analysis of Hinge Force of Scissors Jacking Mechanism
In this paper,the theoretical derivation of the hydraulic cylinder thrust of the scissors jacking mechanism is carried out according to the principle of virtual work.And the rigid body dynamics simulation verification is carried out by using finite element analysis software to conform the correctness of the theoretical calculation formula.at the same time,through simulation,the characteristics and changing laws of the hinge force at each moving vice of the scissor structure are obtained.This provides an important reference for the design of scissors jacking mechanism.
