计及眼睛和头部转动的工程车辆视野性能研究

Study of the Vision for Eye-Head Rotation in Earth Moving Machinery

利用眼椭圆 ,从人机工程学原理出发 ,根据人的视觉特性 ,在充分研究和分析工程车辆驾驶员特点的基础上 ,对其垂直视野进行研究·分别用图解和计算两种方法解决了计及眼睛和头部转动时 ,垂直视野确定问题 ,同时判断视野的舒适性·该方法为工程车辆的舒适性视野设计提供了理论工具 。

This paper researches on the vision for eye head rotation in earth moving machinery by using ergonomics. Driver's eye ellipses offers a tool for designing vehicles to meet vision requirements. The vision for eye head rotation of earth moving machinery was studied based on eye ellipses. A graphic method and a mathematics formula were developed to determine the azimuth and elevation angles of target in the forward field of view,on the basis of analysis of the earth moving machinerys characteristics. It provides not only a new practical design tool for the earth moving machinerys comfort vision,but also a practical check tool for the earth moving machinerys vision and body.
