of the relative velocity as shown in Figure 10-5c. The relationship of the dynamic damping force
Fd as a function of relative velocity for all these cases can be expressed as:
(10.15a)
where c is the constant damping coefficient, v is the relative velocity, and r is a constant which
defines the type of damping.
For coulomb damping, r = 0 and:
For viscous damping, r = 1 and: For quadratic damping, r = 2 and:
