Problem 4 Consider the follower has the following motion characteristics: • Rise to h= 40 mm with a cycloidal motion for 0=0° to 120°, Dwell at h = 40 mm for 0= 120° to 0= 2400 Return (fall) to 0 mm with a harmonic motion for 0=240° to 0= 360° (a) Fill the following table 00 10 30 60 90 120 240 300 y (mm) 0 270 330 360 0 (b) Draw the cam profile for inline radial roller follower of radius R-15 mm. The base circle radius is 25 mm and the cam is rotating clockwise. (c) Sketch roughly the following diagrams (versus cam angle (0) where 0< 0 < 360): follower displacement diagrams follower velocity diagram follower acceleration diagram
