Dynamic friction is determined from the static friction as shown in Equation 1 where FF is the dynamic friction factor.
Equation 1 | Dynamic frictional stiffness Kfric,dyna, static frictional stiffness Kfric,static, friction factor FF, static friction coefficient μ, vertical force F and static displacement δ.
Dynamic friction, in contrast to static friction due to velocity of the vibrations, is not well defined by empirical values. The dynamic friction factor FF has therefore been used to vary the dynamic friction to obtain a best fit between the measurements and the beam type FEA analysis.
