六自由度汽车驾驶运动模拟器设计

摘要

汽车驾驶模拟器是一种用于汽车产品开发、“人—车—环境”交通特性研究或驾驶培训的重要工具。近年来，由于具有安全性高、再现性好、可开发性强、成本低等显著特点，研究开发驾驶模拟器已经成为国内外一个重要发展方向。

本文在查阅国内外大量资料的基础上，结合老师的研究课题主要对六自由度汽车驾驶模拟器液压系统部分进行设计。六自由度汽车运动模拟器采用液压伺服阀控制液压缸来驱动模拟平台的运动，以实现汽车驾驶模拟器运动姿态模拟。本文主要进行机械机构的设计、液压伺服系统设计、液压泵站设计和液压缸的设计等。

通过模拟器的机构设计和驱动液压伺服系统设计，结合电气系统能够实现汽车在不同运行状态的模拟，当驾驶员坐在驾驶舱系统的座椅上进行模拟驾驶时，完全能够感受到实际汽车驾驶的各种体感，为实车训练驾驶提供了可替代的模拟平台；本设计也为今后的进一步研究及其在娱乐模拟器、动感电影等产业的实际推广和应用方面奠定了基础。

Abstract

The Automobile-driving i an important tool which used for the development of auto mobile product and the study of the transportation characteristics of “man-car-environment” or the driver training .In recent years, the study of the automobile-driving simulator used for development has become an important development direction in the world because of the notable characteristics of high safety, well reappearance of scene, easy to develop乙硫氮 and low cost.

This article is based on searching the large quantity of information about at home and abroad, and combines with the teacher’s research task which mainly designs the part of 6-dof driving Simulator of hydraulic system .The 6-dof motion simulator adopts t型槽尺寸valves of hydraulic servo to control actuator to drive the movement of driving simulation platform, and to achieve the movement posture simulation of the automobile driving simulator. This article is mainly about the designing of machine, the system of hydraulic servo, hydraulic pump station, and actuator and so on.

According to the designing of agencies of simulator and hydraulic servo system, it can combines the electrical system which can bring out the imitation of cars in different movement conditions, when the driver simulating drive on the seat of cockpit system, you can feel the feeling of driving a true car, and 铜工艺it also offer the simulator platform which can be replaced for true driving training. At the same time, this designing is also establishes for the further researches and the practice extension and use.
