When the animation is suspended , click at the red ball and drag the mouse button to change its tangential vector , 此時若在紅球位置按下滑鼠鍵拖動滑鼠,將可改變紅球切線速度大小,
Firstly , a simple and practical representing method of the tooth edge tangential vector is applied to replace the traditional differential formula , the simple solving technique of edge contact problem makes the geometric edge contact analysis of the complex curve surface realize . secondly , using numerical searching and mathematical programming method solves the contact directions and loaded contact problem . finally , whole numerical simulation method is provided for loaded tooth contact analysis of high contact ratio spiral bevel gears 首先以一種簡單實用的輪齒邊緣切矢量的數(shù)學(xué)表示方法取代了經(jīng)典的微分表達式,大大簡化了幾何邊緣接觸的求解,使復(fù)雜曲面的幾何邊緣接觸分析得以實現(xiàn);其次又采用數(shù)值搜索與數(shù)學(xué)規(guī)劃法求解了邊緣接觸的主方向和承載接觸問題,為高重合度弧齒錐齒輪承載嚙合全過程的數(shù)值仿真提供了完整的方法。
