Study of Nonlinear Dynamic Characteristics of Joint Configuration

Joint configuration reveals some nonlinearity under different conditions. In this paper, a bolted joint structure subjected to different preload and external excitation is designed to study the nonlinearity dynamic characteristics of assembled structure. At the same time, nature frequent and damping nonlinear characteristics of the bolted connection are analyzed based on energy dissipation theory. The urgency of discussing the nonlinear characteristics of the joint configuration is discussed, and the theoretical and experimental foundation was established.
