Dynamic Analysis of The Hydraulic Scissors Lift Mechanism

In this study, model of lifting platform consisting of scissors and hydraulic cylinder is formed. Static state equations have been used for the mathematical model of the mechanism. The weights and mass inertia moments of the platform members and the upper table have been neglected. Vehicle load as a point force, the top of the table is closed at the moment when the mechanism is effective. The sliding in the joints have been neglected. The mechanism is modeled and simulated in order to evaluate several application-specific requirements such as dynamics, position accuracy etc. The system has a 5 degree of freedom. The simulation gives different link lengths of the mechanism over a linear displacement.
