PROE如何制作螺旋线

1、有限元PRO/E如何制作螺旋线作螺旋线有以下二个方法：1、formed curve ; 2、利用方程式from equation一.Formed curve:1、 首先建立缺省的datum plan；并建立一个参数p,用来控制螺旋圈数set up/parameters/create/real parameters，初始值可以设为：12、建立圆柱体或者圆柱曲面，如以下图：L:NDRM-3、建立form curve,选择tang plane为sketching plane,选择圆柱体的顶面为top,然后绘制如以下图直线：考前须知：a、对齐直线的两个端点右上端点对齐圆柱的top面，左下端点对齐圆柱轴

2、线和tang plane的交点b、建立coordinate system，并对齐直线的左下端点www . 2 O F4、 建立relation:sd#=L*P*PI*DL为圆柱的长度P为参数第一步建立的参数D为圆柱的直径PI为兀2、建立datum curve ,选择from equation3、选择coordinate system,圆柱坐标(cylindrical )此时出现以下信息：5、regenerate后你可以看至V生成的helical curve了。1、首先建立缺省的datum plan, coordinate system/*For cylindrical coordinatesy

3、stem, enter parametric equation/*in terms of t (which willvary from 0 to 1) for r, theta and z/*For example:for a circlein x-y plane, centered at origin/*and radius =4, the parametric equations will be:/*/*theta = t* 360/*声匡区有限元DZnFEA. C M/*-其中螺旋线的方程式为：r = minimum radius of helix + t * (major radius

4、 of helix - minimum radius of helix)theta = t * (pitch of helix * 360 * leading angle (if any)z = desired height + t在弹出的信息文档内输入以下数值：/ For cylindrical coordinate system, enter parametric equation /* in terms cif t (which uil 11 varyFrom 0 to 1) for r# theta and z /* For example: for a circle in x-y planercentered at origin /* andradius = 4, the parametric equaticns will be:r = 4/*theta = t * 360/Hz = 0/H-5 = 4 +
