各种曲线数学方程(All kinds of curve mathematical equations) The proe curve equation is big [author: zflyday date: 2007-10-25 02:20:19 sentiment: 381] 1. Disc spring Cylindrical coordinate R = 5 Theta = t * 3600 Z = (sine theta - 90) (3.5 *) + 24 * t 2. The folium Cartesian coordinates A = 10 X = 3 * a * t/(1 + t ^ (3)) Y = 3 * a * (t ^ 2)/(1 + t ^ (3)) 3. Helical curve Cylindrical coordinates (cylindrical) R = t Theta = 10 + t * (20 * 360) Z = t * 3 4. Butterfly curve Spherical coordinates Rho is equal to 8 times t Theta = 360 * t * 4 Phi is equal to minus 360 times t times 8 5. Involute Cartesian coordinate system R = 1 Ang = 360 * t S = 2 * PI * r * t X0 = s * cos (ang) Y0 = s * sin (ang) X = x0 + s * sin (ang) Y = y0 - s * cos (ang) Z = 0 Spiral. Cartesian coordinates X = 4 * cos (t * (5 * 360)) Y is equal to 4 times sine of t times 5 times 360. Z = 10 * t 7. Logarithmic curve Cartesian coordinate system Z = 0 X = 10 * t Y = log (10 * t + 0.0001) 8. Spherical helix Spherical coordinates Rho = 4 Theta = t * 180 Phi = t * 360 * 20 9. Double arc epicycloid Cartesian coordinates L = 2.5 B = 2.5 X = 3 * b * * cos cos (t * 360) + l (3 * t * 360) Y = 3 * b * sin (t * 360) + l * sin (3 * t * 360) Line 10. Star line Cartesian coordinates A = 5 X = a * (cos (t * 360)) ^ 3 Y = a * (sin (t * 360)) ^ 3 Heart line 11. Cylindrical coordinate A = 10 R = a * (1 + cos (theta)) Theta = t * 360 12. The spiral in the circle Cylindrical coordinate system Theta = t * 360 R = 10 + 10 * sin (6 * theta) Z = 2 * sin (6 * theta) Sine curve Cartesian coordinate system X = 50 * t Y = 10 * sin (t * 360) Z = 0 14. The sun line Cylindrical coordinates R = 1.5 * cos (50 * theta) + 1 Theta = t * 360 Z = 0 15. Fermat curve (a bit like thread) Mathematical equation: r * r = a * a * theta Cylindrical coordinate Equation 1: theta = 360 * t * 5 A = 4 R = a * SQRT (theta * 180 / PI) Equation 2: theta = 360 * t * 5 A = 4 R = - a * SQRT (theta * 180 / PI) Since Pro/e can only do continuous curves, it can only be
