The dynamics of two Degrees of Freedom (DOF) mass-spring-damper system, resting on a moving belt are investigated. Due to friction force generated between the moving belt and the masses, the friction model plays a significant role on the energy transfer between the contacting surfaces. Therefore, in this study a steady-state and a dynamic friction models are implemented. The influence of these friction models on the system response is investigated. Additionally, the both systems where subjected to a number of initial conditions, to address the system dependency on the initial conditions. Finally, using the provided governing equations and the systems jacobain matrices Lyapunov exponent spectra were calculated.
