This article takes the lagrange equation as the principle, establishes mathematics modeling to the inertia brake vibration when it brakes, then simulates it with matlab. this paper educed the relation equations between, which are the inertia brake ' s friction coefficient of the brake ring and the friction disk, the mean radius, the braking force, rotation inertia of the driving top and the spline shaft, spiral climbing angle of the brake ' s concave - convex helicoid, the mean effort radius of the concave - convex helicoid, elasticity coefficient of the spring, quality of the driving top and the spline shaft, rotations inertia of the brake ' s rotation part besides the driving top and the spline shaft, suppresses sleeve. provides the theory basis for the inertia brake structure optimization
本文以拉格朗日方程為理論基礎，對慣性制動器在制動時的振動進行數學建模，然後用matlab對其進行模擬，得出了慣性制動器在制動時振動角頻率分別與制動環和摩擦片之間的摩擦系數、制動力的平均半徑、主動頂和花鍵軸的轉動慣量、慣性制動器的凹凸螺旋面的螺旋升角、凹凸螺旋面平均作用力的半徑、彈簧的彈性系數、主動頂和花鍵軸的質量、慣性制動器除主動頂和花鍵軸外其他部分的轉動慣量和、頂壓套的質量等慣性制動器各零部件的物理參數之間的關系，為慣性制動器的結構優化提供了理論依據。 -
Proceed from the angle of enhancing the backing off grinding accuracy of the special shaped convex curved rake surface, and in accordance with the enveloping theory of differential geometry and the designing model of new configured carbide gear shaper cutters, the mathematical model for backing - off and grinding the special shaped convex curved rake surface of the new configured gear shaper cutters was derived
從提高新構形硬質合金插齒刀異形凸曲前刀面鏟磨精度的角度出發，根據微分幾何的包絡理論及新構形硬質合金插齒刀設計模型，推導出鏟磨新構形插齒刀異形凸曲前刀面的數學模型。 -
After research surface reconstruction with triangular facets, contours of first layer and the last layer are triangulated with layer separation algorithm firstly. and then the least polar - angle criterion is presented for linking two convex contours, and the method is also given in which non - convex contour is transformed to a set of convex contour. with the splitting and integrating algorithm, the single - to - multi - contour reconstruction with triangular facet has been simplified to one - to - one contour
首先採用層析式演算法對起始層和結束層中的輪廓進行三角剖分；然後採用最小極角法實現兩凸輪廓間的三角片重構，並討論了非凸輪廓變換為凸輪廓的方法；最後，使用分裂與合併技術將單輪廓匹配多輪廓的三角片重構簡化為單輪廓之間的三角片重構，最終完成整個骨骼表面的三角片重構。 -
Four - sided faces only work well if the face is pretty much flat ( all points lie within one imaginary plane ) and convex ( the angle at no corner is greater than or equal to 180 degrees )
四邊面只有在面是非常平整並且是直角的時候工作才是最好的（也就是四點處同一平面上） 。
