Analysis and Simulation of the Erection Mechanism with Floating Back-pivot

Traditional erection mechanism is restricted in narrow space.Aiming at the problem,a new erection mechanism with floating back-pivot was proposed and its physical model and mathematic model based on vector loop equations were set up.The kinematics and dynamics equations of the mechanism were given.The dynamic simulation model based on the kinematics and dynamics equations was built in Matlab/Simulink.With the prescriptive conditions of erection time and driven mode of the jack,the dynamic simulation for the new erection mechanism was made using co-restriction method.The analysis and simulation conclusions demonstrate that the mechanism can satisfy fast and steady request and erection space is economized effectively.
