DescriptionEasement curve.svg |
English: This is an example of a red easement (transition) curve between a blue straight line and a green circular arc. The circular arc is supposed to start at the end of the red easement curve. However, it is drawn as a full circle here.
Sage source code: var('t')
p = integral(taylor(cos(t^2),t, 0, 12), t)
q = integral(taylor(sin(t^2),t, 0, 12), t)
x1 = p.subs(t = 1)
y1 = q.subs(t = 1)
R = 0.5
x2 = x1 - R*sin(1.0)
y2 = y1 + R*cos(1.0)
r1 = parametric_plot([p, q], (t, 0, 1), color = 'red')
r2 = line([(-1.0, 0), (0,0)], rgbcolor = 'blue')
r3 = circle((x2, y2), R, rgbcolor = 'green')
show(r1 + r2 + r3, aspect_ratio = 1, axes=false)
Русский: Пример переходной кривой (красная) между прямой линией (синяя) и круговой кривой (зелёная). |
