| As a new industry technology, virtual prototyping (VP) technology has been used in many fields and shown great technical advantages and economic benefits. Due to the advantage of the new technology VP, in order to improve the uncompleted aspects in the traditional design of steering system of the dual-front-axle heavy trucks, the new technique is applied in the field of the heavy trucks design process. The multi-body steering system model of a dual-front-axle heavy trucks using ADAMS software was established, which contains body, steering wheel, recirculating ball steering gear, double-front axle, dual-rocking arms, suspension, king pin and the front wheels etc. According to the created virtual model and simulative result, we analyze the kinematics capability of steering system of the dual-front-axle heavy truck as well as the check of its intervene movement, especially discussing the dynamics analysis of steering system under the instruction of Virtual Prototyping, moreover, we do some optimization design of double rocking arms.In order to further validate the correctness of the dual-front-axle steering system designs, the mathematical model of steering system is also built up, and analysis and calculations of some main components of the hydraulic power steering system are given. Furthermore, the virtual hydraulic system is built by use of the hydraulic module of ADAMS, accordingly, the mechanical and hydraulic systems are integrated via the two-way cylinder, which lay the foundation for mechanotronics. |
