1. A follower is required that should rise through a total displacement of 10 inches with half cycloidal motion in 130" of cam rotation and dwell at 10 inches for 90. Then the follower should return to the zero position with full simple harmonic motion in 90 of cam rotation and finally dwell for 50 before repeating the cycle. b. In an Excel spreadsheet determine the heights in each of the above segments for 0 360 a range of 0s8s3...

8.7 Draw the displacement schedule for a follower that rises through a total displacement of 3 in with cycloidal motion in 120° of cam rotation. The follower then dwells for 90° and returns to 0° with simple harmonic motion in 90° of cam rota- tion. The follower then dwells for 60° before repeating the cycle.
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 t...
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.

2. (8 points) A cam with a knife-edge follower has a motion with the following characteristics: lift = 50 mm base circle radius = 25 mm outstroke = 110 degrees cam rotation with cycloidal motion first dwell = 80 degrees return stroke = 90 degrees with simple harmonic motion Cam rotates at 550 rpm in CCW direction Determine the maximum velocity and acceleration of the follower during outstroke and return stroke.
A translating cam-follower is to be designed for a Rise-Dwell-Fall-Dwell (RDFD) application in which vibrations must be considered
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...
