This paper investigates the nonlinear vibration isolation problem of simply supported beam bridge structures under displacement excitation, employing the Incremental Harmonic Balance Method (IHBM) to derive an approximate analytical solution for the nonlinear vibration response of the beam. The research focuses on a coupled system consisting of a quasi-zero stiffness (QZS) isolator, constructed using a three-spring system, and a simply supported beam bridge. Based on the classical Euler-Bernoulli beam theory, the governing equations of motion under displacement excitation are established and systematically solved using the IHBM, with the entire analytical process thoroughly derived. The study transforms the final solution into a linear matrix equation using generalized coordinates, achieving a procedural and standardized computational process. To validate the reliability of the IHBM approximate analytical results, the study compares the IHBM computational results with numerical solutions obtained using the fourth-order Runge-Kutta method (ODE45). The results demonstrate that the IHBM method exhibits significant advantages in computational stability and result completeness. Additionally, through parametric analysis, the study explores the influence of key isolator parameters on system amplitude, further confirming the effectiveness and engineering practicality of the IHBM in nonlinear vibration isolation research. The research outcomes provide new theoretical foundations and methodological references for the nonlinear vibration isolation analysis of simply supported beam structures, offering important guidance for engineering practice.

本文针对位移激励作用下简支梁桥结构的非线性隔振问题展开研究,采用增量谐波平衡法(Incremental Harmonic Balance Method,IHBM)求解简支梁桥非线性振动响应的近似解.以三弹簧体系构成的准零刚度(Quasi-Zero Stiffness,QZS)隔振器与简支梁桥耦合系统为研究对象,基于经典欧拉-伯努利梁理论,建立了位移激励下的运动控制方程,并通过IHBM进行了系统性求解,完整推导了其解析过程.研究采用广义坐标形式,将最终求解结果转化为线性矩阵方程,实现了计算过程的程序化与标准化.为验证IHBM近似解析结果的可靠性,研究将IHBM计算结果与四阶龙格-库塔算法(ODE45)的数值解进行了对比分析,结果表明IHBM方法在计算稳定性和结果完整性方面均表现出显著优势.同时,本研究通过参数化分析探讨了隔振器关键参数对系统振幅的影响规律,进一步证实了IHBM在非线性隔振研究中的有效性和工程实用性.本文成果为简支梁结构的非线性隔振分析提供了新的理论依据和方法参考,对工程实践具有重要的指导意义.
