a = Normal distance between the follower center and the axis of rotation of the cam at initial position
A j = Constant coefficients ( j = 1, , n)
C j = Viscous damping coefficient of follower (used in addressing nonrigid follower)
C s = Viscous damping coefficient of the restoring damper
d = Deviation of cam-follower position from static equilibrium position
d ?= First derivative of deviation
d ? = Second derivative of deviation
E i,j( x) = Spline function values at constraint locations ( i, j = 1, , n)
F c = The contact force (used in addressing nonrigid follower)
F j = Kinematic constraint values ( j = 1, , n)
F p ? = Preload (used in addressing nonrigid follower)
h = Rise of the follower
k = Order of spline function
K f = Spring constant of follower (used in addressing nonrigid follower)
