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.

微分控制方程的摄动方法及其在弯梁动力特性分析中的应用

作为弯梁动力学研究领域的重点，弯梁动力学系统的仿真已成为弯梁动力学研究的重点。本文创造性地将弯梁动力系统中弯梁的单位值作为摄动值，解决了摄动系统中的模态叠加问题。在实验验证部分，将弯曲梁单元的摄动模拟结果与直线梁单元的摄动模拟结果直接进行比较。实验结果表明，所提出的弯梁单元模型具有良好的收敛性和有效性。
