Problem 1 (300pts)
Write a Matlab script(s) that uses the SCCA equations to design three cams to meet the
specifications below:
• Rise 12cm in 100°, Dwell 120°, Fall 80°, Dwell remainder. Use cycloid displacement.
4500 RPM.
• Rise 18cm in 160°, Dwell 90°, Fall 90°, Dwell remainder. Use modified trapezoid.
18 rev/s.
• Rise 4cm in 140°, Fall 140°, Dwell remainder. Use modified sinusoid. 1400°/s
You may use the standard values for a, b, and c - check slides on blackboard. For each cam,
address the following points:
• Generate plots of s, v, a, and j using a resolution of 2°.
• Calculate the maximum linear velocity and acceleration of the follower.
