Mine sport utility vehicle overall design compared with other ordinary vehicles in the basic technical approach taken, though not much difference, but the purpose of its own structure, bearing, functional, structural complexity, braking stability, regulations adaptability is much more complicated, and the overall design to consider their problems more thorough and comprehensive. In this article, mainly engaged in the study of the following aspects: first: the mine with the determination of the overall parameters of the sport utility vehicle. The overall parameters determine mine the main content of the work of the overall design phase of the off-road vehicle, initially set the main parameters of the vehicle, including the overall size, quality, and performance parameters include the main structure of the product overall layout parameters and major the determination of the assembly configuration. Second: the calculation and analysis of vehicle performance. The calculation and analysis of vehicle performance numerical calculations, determine the product performance parameters that must be carried out in order to effectively control the vehicle performance parameters to adapt to the the vehicle actual work situation. Do lightweight, economic, energy-saving, stability, security and other goals. Third: The general layout of the design. The general layout is the argument of the vehicle overall program basis, is a main parameter according to the determined vehicle detailed general layout design, build a the vehicle overall layout of the three-dimensional data model, using a computer to calculate or some of the properties and parameters of the simulation vehicle . Further verify and amend the general parameter values, and in-depth research and analysis to determine the other relevant parameters. Finally, determine the the vehicle overall layout structure. Fourth: frame finite element calculation. Frame as the main load-bearing parts of the vehicle, its stiffness and strength check is necessary to bend and twist, analytical frame of displacement and stress cloud by simulating car in different conditions frame by as The frame structure optimized to provide the basis. This paper applications AUTOCAD the general layout of the vehicle, the use of CATIA modeling and HYPERMESH pre-treatment of the model, ANSYS model post-processing, the major components of the car to simulate and optimize the design. By more than a few key aspects of the design, the final design of the mine with the performance of off-road vehicles to meet the design requirements. Currently no related enterprises engaged in the study of the types of vehicles, the car completely rely on independent innovation, independent research and development. In the overall design of the car, there are many innovations, such as the X-shaped beams of the frame design, hanging around the strong point of the original design are the car, while the car's multi-link coil spring suspension system The design highlights of the car.
