In view of the poor characteristics of this curve, mathematical presentation is omitted. 6 CONSTANT ACCELERATION CURVE This curve of the polynomial family is also known as the parabolic curve and has constant positive and negative acceleration values. The curve has the smallest maximum accelerations for all curves possible (Fig. 4). 3. Modiﬁed constant velocity curve with circular area—DRD cam. 4. Acceleration, y" Constant acceleration curve—DRD cam. substituting in Eq. 20) 36 CAM DESIGN HANDBOOK The boundary conditions are q =b b q= 2 q =b y =h 2h y¢ = b y¢ = 0 yield constants C0 = - h, C1 = 4h -2 h , C2 = b b Substituting in Eq.
Note, the acceleration is negative because the follower is reversing its acceleration in a minus, downward direction. Also, mathematically speaking, the slope is to the left (second quadrant), which means a negative value. The jerk values may be approximated in the same manner by plotting the acceleration curve and ﬁnding the slopes. 3 BASIC CURVE CLASSIFICATION In this chapter we present some basic curves of the DRD type and their kinematic relationships. In design, the ﬁrst step is to sketch a time chart (discussed in Chap.
