Co-simulation Of Mechanical-Hydraulic Combined System And Structural Analysis For A New Tapping Vehicle

New tapping vehicle is a kind of heavy-duty transporter,mainly used for transporting,loading and unloading the liquid aluminum in steel smelting process. It will replace the traditonal way in which crown block,forklift and crane are used together in steel smelting process. It is the most advanced transportation way in aluminum production at present,and its developing will have great significance for chinalco’s automatical production.The paper is aimed for developing the new tapping vehicle.By applying multidisciplinary collaborative simulation technology and finite element technology,the new tapping vehicle’s dynamic characteristic and finite element analysis were finished.Main research work are as follows:By using ADAMS software based on multi-rigid-body dynamics theory, the new tapping vehicle’s structure,constraint,drive and fiala tire model were deeply studied.Finally,the multi-rigid-body dynamics model of the new tapping vehicle was built in the paper.By solving the interface technique between ADAMS and AMESim software, the co-simulation model of the mechanical-hydraulic combined system for the new tapping vehicle had been set up.On that basis,the steering PID controller for the new tapping vehicle was bulit based on AMESim. The results show that PID controller is feasible.By using ADAMS and AMESim,the co-simulations of climbing10%slope and pivot steering were completed. Then the vehicle’s climbing ability,steering qualities,driving smoothness,kinematics and dynamics parameters were obtained.The co-simulation results show that the co-simulation model and simulation methods in the paper are right.Based on finite element theory, the finite element models of carriage and door frame of the new tapping vehicle were built in the paper by using ANSYS software. And according to the kinetic parameters got from the co-simulation of climbing10%slope, the finite element analysis for the carriage and the door frame were finished. The finite element results show that the strength and the stiffness of the carriage and the door frame satisfie the design requirements, and the design of the tapping vehicle is safe in the paper. By using ADAMS software,a virtual prototype of the testing bench was bulit.Then,the research on tire’s displacement response characteristic under radial excitation force was completed.By comparing simulation datas with experimental results,we can see they fit well.So,the tire modeling by using ADAMS software is correct.
