摘要

螺栓法兰连接结构广泛应用于机械结构和航空航天结构，由其构成多个结构组件（如火箭舱段）之间的连接面，引入的非线性动力学特性会显著影响整体结构动力学响应。不同于以往研究中所聚焦的单个非线性连接面对结构响应影响问题，本文针对具有两个螺栓法兰连接面的组合结构开展非线性耦合振动分析，研究连接结构动力学参数对结构响应的支配效果，以便获得有效控制结构响应的关键非线性特征。基于螺栓法兰连接结构等效双线性弹簧模型，建立双连接面螺栓法兰结构多自由度耦合振动模型，分别讨论了在不同形式的激励作用下的响应和相空间特性，揭示系统的阻尼敏感性及特定参数条件下的超谐波和亚谐波共振现象，最后分析弹簧刚度比及部段质量比对结构响应的影响。

Abstract

Bolted flange connections are widely used in mechanical and aerospace structures, which form a connecting surface between two structural components, such as rocket segments, and the nonlinear dynamics introduced can significantly affect the overall structural dynamics response. Unlike the single nonlinear connection focused on in previous studies, this paper proposes nonlinear coupling vibration analysis on the combined structure with two bolted flange connection surfaces, and studies the dominant effect of the dynamic parameters of the structure on the response, to find out the key nonlinear characteristics for effective response control. Based on the equivalent bi-linear spring model of bolted flange structure, a multi degree of freedom coupling vibration model of double connecting surface structure is established. The response and phase characteristics under different excitations are discussed to reveal the damping sensitivity of the system, the super-harmonic and sub-harmonic resonance phenomena. The influence of the spring stiffnesses ratio and mass ratio on the structural response is analyzed.
