Abstract

This article mainly studies the forced vibration characteristics of slender beam members under periodic excitation of the support. Firstly, the research background and significance are introduced, and a summary of the current domestic and international research status is given. Then, based on the foundation of vibration theory, a forced vibration model of slender beam members is established, and numerical simulation analysis is carried out using comsol software. Through the study and analysis of characteristic frequencies, frequency domain, and transient response, the influence of excitation frequency and amplitude on the forced vibration characteristics is explored. Finally, a summary of the entire research is made, and future research directions and prospects are proposed. This study has certain reference value for understanding and predicting the forced vibration characteristics of slender beam members under periodic excitation of the support.
