1. purpose and significance

with the rapid development of computer simulation technology, graphics real-time processing technology and virtual reality technology in recent years, it has provided powerful tools and help for vehicle simulation technology^[1]. the advent of vehicle driving simulation technology, providing a great help for us in the vehicle driving learning. driving simulation system can be equipped in the universities, driving training schools and professional place for car entertainment and so on. with the rapid development of driving simulation system, the cockpit also following up^[2]. the follow-up of the dedicated cockpit technology for driving simulation systems is also particularly important^[3].

for a system, its performance depends not only on the individual performance of each component, but also on the interrelationships of the elements in the system such as energy, transfer, processing and control between substance and information^[4]. the cockpit design of the driving simulator follows the principles of ergonomics which includes the overall study of the characteristics of the drivers, the driving simulator, the virtual environment, and the characteristics of the elements of the simulated environment^[5]. the primary purpose of this work is to find the best combination of programs to achieve the best conditions and improve the overall performance of the simulator^[6]. at the same time meet the safety, comfort and efficiency requirements.

until this moment, there are about 40 research institutions in the world that have a driving simulator for an independent research and development of a professional driving simulator design^[7]. in germany, sweden, united states and japan, the major car manufacturers and research institutes have updated their own development of the driving simulator. they are constantly improving the vehicle mechanics model, their system can simulate up to six degrees of freedom of movement. one of the visual systems also uses computer imaging technology, it can provide a very realistic vehicle environment^[8].

2. 研究的基本内容与方案

2. the basic content, objectives, technical solutions and measures

2.1 basic content and objectives:

the cockpit of a driving simulation system is mainly used to simulate some of the movement structure in the cockpit and its control system. some of the main objectives of a driving simulator are to achieve a tactile feel by real simulation of the real car driving process in a limited cockpit space, such as uneven road, start, accelerate, slow down and parking, left and right shaking and other similar sense of traffic^[13]. through a number of degrees of freedom of the parallel mechanism and its control system completely simulate the actual car driving process in a variety of body sensation, in order to achieve three-dimensional space in any direction of movement, including three basic directions of movement pitch, roll and swing^[14].

consider human factors, analyze human behavior, and other factors to optimize the design of the components inside the cockpit. the arrangement of seats, operating devices and the display and the deign of a simulator can be done according to the sitting comfort and automotive overall design^[15].

catia, cad, ansys and other software will be used for the modeling and analysis of the design for a for a six-degree-of-freedom driving simulation system cockpit. the cockpit can be moved in any direction in the three-dimensional space according to the commands issued by the control system. using knowledge of ergonomics to analysis cockpit, the reasonable layout of various parts of the hardware facilities.
