Problem 3 on cams/ roller follower with simple harmonic motion/ Velocity & Acceleration diagram

cam with minimum radius of 25 mm, rotating clockwise at a uniform speed is to be designed to give roller follower, at the end of valve rod, motion described below : 1. To raise the valve through 50 mm during 120°rotation of cam. 2. To keep the valve fully raised through next 30° 3. to lower the valve during next 60° 4. to keep the valve closed during rest of revolution i.e. 150° The diameter of roller is 20 mm and diameter of cam shaft 25 mm Draw the profile of cam when 1. the line of stroke of valve passes through the axis of cam shaft 2. the line of stroke is offset 15 mm from axis of cam shaft The displacement of the valve, while being raised and lowered , is to take place with simple harmonic motion. Determine the maximum acceleration of valve rod when the cam shaft rotates at 100 rpm Draw the displacement, the velocity and the acceleration diagram for one complete revolution of cam #cam #camandfollower #simpleharmonicmotion #rollerfollower #theoryofmachine #tom #camprofile #displacementdiagram #velocitydiagram #accelerationdiagram Please support my channel, subscribe and share my videos with friends.
