Vibration energy characters study of a soft-core beam system coupled through nonlinear coupling layers

Abstract

To ascertain the potential impact of nonlinear coupling layers on the vibration control of composite beam systems, this study develops a vibration analysis model of a nonlinear coupling-layered soft-core beam system. Ascertain the accuracy of the vibration responses computed by the soft-core beam system using the Galerkin truncation method (GTM) in comparison to the results obtained through alternative methods. The correct calculation results indicate that nonlinear coupling layers are the cause of nonlinear phenomena in the soft-core beam system. Nonlinear coupling layers are responsible for nonlinear phenomena of the soft-core beam system, such as peak-jumping and the region with multiple continuous amplitudes, according to numerical results. To reduce vibrations in the soft-core beam system's resonance regions, reasonable parameters for the nonlinear coupling layers are advantageous. When the soft-core beam system is excited at a single frequency, the kinetic energy responses include converted values of nonlinear coupling layers. Using nonlinear coupling layers, it is possible to establish an effective parameter range for the vibration energy control of the soft-core beam system. The utilization of reasonable parameters in nonlinear coupling layers can effectively mitigate the vibration energy of a soft-core beam system that is excited at a single frequency. The soft-core beam system induces the desired energy transfer phenomena at specific time intervals and under particular conditions.
