Wave Transmission and Energy Dissipation at Structural and Machine Joints

Abstract

The dynamics of composed structures is influenced by the transfer behavior of interfaces of bolted, riveted, and compression joints. The measured nonlinear behavior of such joints is represented by equivalent linearized models and coupled with models of the members. Excitations by incident flexural waves, as well as longitudinal waves, are discussed. Characteristics of wave transmission, wave reflection, and energy dissipation of jointed beams are calculated. The influence of different models of joints is compared. A test setup for experimental vertification is proposed.
