Question #196811

.A cam is to be designed for a knife edge follower with the following data:1. Cam lift = 60 mm during 90° of cam rotation with simple harmonic motion.2. Dwell for the next 30°.3. During the next 60° of cam rotation, the follower returns to its original position with simple harmonic motion.4. Dwell during the remaining 180°.Draw the profile of the cam when the line of stroke isoffset 20 mm from the axis of the cam shaft. The radius of the base circle of the cam is 50 mm. Determine the maximum velocity and acceleration of the follower during its ascent and descent, if the cam rotates at 250 r.p.m.

Expert’s answer

Maximum velocity of the follower during its ascent and descentWe know that angular velocity of the cam We also know that the maximum velocity of the follower during its ascent and maximum velocity of the follower during its descent We also know that the maximum acceleration of the follower during its ascentand maximum acceleration of the follower during its descent
