Design a rise-fall-dwell cam-follower motion profile that will rise from 0 to 7 mm in 0.5 seconds, then fall for 0.5 seconds back to 0 mm, and then dwell for 1 second. Note that this produces a symmetric rise-fall curve. There should be no overshoot, and the motion should be relatively smooth. Your final follower motion profile s(θ) should be in terms of cam angle θ.

A translating cam-follower is to be designed for a Rise-Dwell-Fall-Dwell (RDFD) application in which vibrations must be considered. The cam is to move the follower from 0 to 35 mm in 70°, dwell for 100, fall back to 0 mm in 80°, and dwell for the remainder of the cycle. In addition, the cam must rotate at an angular velocity of 60 RPM. The position (s), velocity (v), and acceleration (a) curves during the rise period are defined by the...

1. (40 points) A double-dwell cam is to move a follower from 0 to 2" in 120°, dwell for 80°, fall in 90 and dwell for the remainder. The total cycle is 5 seconds. Using cycloidal motion for the rise and 3-4-5 polynomial motion for the fall, find the follower displacement corresponding to the cam angle 0 at 90°, 180°, 230° and 320 respectively. Also find the maximum actual acceleration (in inch/sec2) during the entire motion cycle.

Cam Design ProblemDesign a double-dwell cam to move a follower (roller-type) from 0 to 150 mm in 80◦, dwell for 90◦, fall 150 mm in 80◦, and dwell for the reminder of the cycle. The total cam cycle takes 10 sec. Consider an application in which vibrations must be minimized. Assume that the pitch radius, Rp = 500 mm, the cam-follower has zero eccentricity, ε = 0, and the roller raduis is Rf =50 mm. Any other parameters may be...
