高阶非线性减振系统的主动控制的研究
Study on the Active Control of Vertical Nonlinear Suspension System
摘要:
列车减振系统可简化成单自由度振动模型，在这个模型中考虑五次非线性刚度因素，采用时滞阻尼器来控制其竖向振动。采用多尺度法分析，得出系统的理论近似解，研究非线性刚度系数、阻尼系数、反馈增益系数和时滞量等因素对竖向振动的减振效果，并分析其规律，为工程应用中的减振项目提供理论指导。
Abstract: The vehicle suspension system can be simplified into a single-degree-of-freedom vibration model. Five nonlinear stiffness factors are considered in this model, and a time-delay damper is used to control its vertical vibration. Using multi-scale analysis, the theoretical approximate solution of the system is obtained. The effects of nonlinear stiffness coefficient, damping coefficient, feedback gain coefficient and time delay on vertical vibration reduction are studied, and the regularity is analyzed, which can provide theoretical guidance for vibration reduction projects in engineering applications.
