SIMPLE HARMONIC MOTION

The output of the cam profile, for the motion curve being simple harmonic motion, for the given specifications of the cam is shown below.

Specifications of the cam:

Base circle radius of the cam: 95

Stroke or lift of the follower: 70

Outward stroke angle: 1200

First dwell period angle: 500

Return stroke angle: 900

Second dwell period angle: 1000

Offset distance of the follower axis from the cam centre: 40

The output i.e. the displacement diagram and the cam profile are
