Perturbation method for differential control equations and its application in the analysis of dynamic characteristics of curved beam

As the focus of the research field of curved beam dynamics, the simulation of curved beam dynamic system has become the focus of the research of curved beam dynamics. This paper creatively takes the unit value of curved beam in the dynamic system of curved beam as the perturbation value, and solves the problem of mode superposition in the perturbation system. In the experimental verification part, the perturbation simulation results of curved beam element are directly compared with that of straight beam element. The experimental results show that the curved beam element model proposed has good convergence and effectiveness.
