Kinematics Analysis And Simulation Of The Balanced Chassis Suspension Of A Vehicle With Multiple Axles

Enterprises in Auto industry of our country faces with a huge challenge that how to set up advantages in competition with foreign Auto manufactures. Mastering modern advanced vehicle design and analysis methods is the base of building competitive advantage. In this paper we'll learn the technology of visual prototype and make a practical use on a special purpose vehicle.The balanced chassis suspension of a multi-axle vehicle used in oil extraction was investigated in this paper. There are problems of overload on axles and poor passing in the vehicle when driving. To find the reason, the structure of vehicle, driving conditions and etc were taken into consideration in vehicle kinematics analysis. After that a new balanced chassis suspension was presented. By comparison kinematics analysis of vehicles with original suspension and new suspension, the new suspension was proved to be viable. Follow that the structure design of components of new suspension was made. Finally with the software ADAMS, the chassis model with new suspension was built to perform dynamic simulation to forecast the performance. And the simulation result shows that the project of suspension is acceptable.In this paper traditional analysis method and advanced technology were both used to solve the task. Traditional way was used for primary analysis. While t virtual prototype were used to build visual product to make dynamic simulation. The use by synthesis of CAD, CAE and visual prototype is one of tendencies of vehicle design and manufacture. It will improve design and analysis levels of Auto industry. The study in this paper is a good try for the technology of virtual prototype in special purpose vehicle design and analysis.
