Experimental and Numerical Nonlinear Modal Analysis of a Beam with Impact: Part II – Experimental Investigation
Abstract
Methods for nonlinear experimental modal analysis, such as nonlinear phase resonance testing, are currently limited to smooth nonlinearities. However, the modeling of systems with contact interactions, being relevant in many industrial applications, often leads to models with strong nonsmooth nonlinearities. This contribution investigates the capability of nonlinear phase resonance testing to analyze systems with nonsmooth nonlinearities. Therefore, a series of automated steady-state measurements with phase controlled excitation is used. The experimental investigation is complemented with the numerical results obtained in Part I of this study.
