Research on transverse vibration characteristics of beam-strut composite system based on analytical method

Abstract

In this paper, the beam-strut composite system is taken as a simplified theoretical model, and the transverse vibration of the model is modeled by analytical method, and the reliability of the model is verified by numerical substitution. Based on this model, the influence of each mode of the system on the final displacement, the lateral vibration response of the system at different excitation frequencies and the influence of excitation displacement velocity on the lateral vibration of the system are analyzed. The results show that the higher the mode order, the smaller the influence of the mode on the final displacement of the system; the system will not resonate at the actual working frequency; the lateral vibration displacement of the system will increase with the increase of excitation displacement speed.
