New Method for Solving Vibration Systems with Clearances

The behavior of vibration systems with clearances is essential from the viewpoint of dynamic design, and a noise and vibration control. Clearance type nonlinearities possess non-smooth force–deflection characteristics (usually modeled as piecewise linear) and generally require a special treatment compared with other types of nonlinearities. There is no general analysis method applied to all nonlinear systems in all instances. Numerous methods, such as standard time-domain numerical integrations, various harmonic balance methods, analog and digital simulations, piecewise linear techniques [3] and the time finite element method have been developed.
