摘    要:探讨了基于虚拟现实的车辆平顺性振动仿真原理,利用软件编程的方法实现了汽车在虚拟道路上的行驶运动。汽车行驶时,能够表现车箱(包括驾驶员)的垂向运动、横向运动和俯仰运动,驾驶员的垂向运动、横向运动和俯仰运动,汽车轮胎的旋转运动。其运动规律皆由车辆平顺性动力学分析数据来确定。从而实现了车辆平顺性振动运动在计算机屏幕上的虚拟显示,以图形图像运动来直观的表现车辆的平顺性。

关 键 词:虚拟现实  车辆平顺性  汽车  虚拟道路  软件编程  可视化仿真

Abstract:The virtual reality theory and implementation of vehicle ride vibration are discussed in the paper. Firstly, the 3D virtual prototype for a Forland truck by using ADAMS is built,and the vehicle dynamic database in time domain is obtained. Secondly with reference to the real world, a virtual road graphics database is established containing road surface, river, grassland, house, trees and cordillera. Finally programmed on OpenGVS SDK, the virtual vehicle ride on virtual road is realized. While the vehicle model is running on the virtual road, the vertical, lateral and pitching movement of the vehicle body and the driver as well as the rotation movement of the four wheels are showed on screen. All their movement rules are decided by vehicle dynamic data.
Keywords:Visual simulation  Vehicle ride comfort  Virtual road  Software programming
