摘要
采用空间解析几何中两个平面之间夹角等于这两个平面法向量之间夹角的原理,推导出斜支臂弧形闸门支铰偏转角计算公式;该公式简洁明了并且计算量小,可为斜支臂弧形闸门的设计、加工提供参考,能提高计算的准确性。
Based on the principle in spatial analytic geometry that the angle between two planes is equal to the angle between their normal vectors,a formula for calculating the deflection angle of the hinge on an inclined arm radial gate is derived.This formula is concise,straightforward and requires minimal calculation.It can serve as a reference for the design and manufacturing of inclined arm radial gates,improving the accuracy of calculations.
