It is a kinds of special train car that can return to the oriental place by their own weight. With the development of productive forces, the accuracy and stability of the car put forward to a higher requirements. Lifting mechanism is an important institution in this car, it is directly related to the lifting quality of the car. This paper describes the use ADAMS / View module to establish a simplified physical model of lifting mechanism and then simulated it. The design requires the pressure is still on the hydraulic cylinder when this institution at the maximum lift angle of the carriage, and the results of lift bearing design and verification of finite element analysis to verify the reliability and validity of the design to ensure the lifting mechanism to meet the job requirements.  The main contents include 1,figure out the parameters of the hydraulic cylinder based on the known parameters of it; 2, based on the parameters obtained by the lifting mechanism to draw the two-dimensional CAD drawings and three-dimensional UG map, and In ADAMS, create simple physical model; 3, lifting mechanism simulation, using ADAMS for simulation, called for lifting the ca
