This paper is motivated by the realization that the phenomena of noise and vibration caused by frictional contact in mechanical systems must be related to the properties of the contact. The three parameters of interest to vibration response are equivalent (macroscopic) contact stiffness, damping and friction function (contact tangential-to-normal load ratio). The dynamic response of a spring-mass-damper in frictional contact with a moving platform is considered. The equations for contact stiffness as well as viscoelastic characteristics are implemented in the equations of motion of mass-spring-damper system. It is shown that the formulation of contact stiffness and force allows the inclusion of frictional contact without the necessity of including friction/velocity relation phenomenologically. That is no assumption of friction/velocity relation is made in the formulation of the governing differential equations. Friction is obtained together with the resulting dynamic response of the system. It is demonstrated that the contact and the mechanical system have a mutual influence, i.e. effect and feedback.
