起重运输机械驾驶室前围角度的计算

运用几何中向量的概念 ,推导出 3个平面两两相交时 ,其二面角与平面角的关系 ,得出 8个计算公式 ,可解决起重运输机械驾驶室的有关角度和展开尺寸的计算。

This paper applies geometric vector concept to derive the relations between double plane angle(angle between two planes)and planar angle when three planes intersects each other,and obtains eight formulae for working out the related angles and expanded dimensions on driver′s cabs of material handling equipment.
