A Study of Hydrostatic and Mechanical Co-Simulation for the Hooklift Operation System

The mechanical system and the hydrostatic system of a hooklift are built using the software of Pro/E and ADAMS(Automatic Dynamic Analysis of Mechanical Systems).The hydrostatic and mechanical virtual hooklift model is established by the integration of the two systems through parameter correlation technology under ADAMS environment and a large amount of kinematic and dynamic simulations and analyses are carried out.It is expected to use the results to predict the feasibility of the design plan and trial-production of the physical prototype so as to raise the speed and precision of product development and reduce the development cost.
