非线性动力学在机械系统设计中的应用
摘 要
本研究探讨了非线性动力学在机械系统设计中的重要应用。随着现代机械系统的复杂性日益增加，传统的线性设计方法已难以满足高精度和高稳定性的需求，因此引入非线性动力学理论显得至关重要。本研究旨在通过非线性动力学分析，提升机械系统的性能与可靠性。我们采用多体动力学仿真软件，结合实验验证，对几种典型的非线性现象进行了深入研究，包括振动、冲击和混沌等。通过对比传统线性设计与非线性设计在相同工况下的性能表现，发现后者在应对复杂动态环境时具有更优越的稳定性和响应速度。此外，本研究还创新性地提出了一种基于非线性动力学的优化设计方法，该方法能有效降低系统的振动幅度，提高机械系统的工作效率和使用寿命。

Abstract
This study investigates the important applications of nonlinear dynamics in the design of mechanical systems. With the increasing complexity of modern mechanical systems, the traditional linear design method has been difficult to meet the requirements of high precision and high stability, so it is crucial to introduce nonlinear dynamics theory. This study aims to improve the performance and reliability of the mechanical system through the nonlinear dynamic analysis. We use many-body dynamics simulation software combined with experimental verification to thoroughly investigate several typical nonlinear phenomena, including vibration, shock and chaos. By comparing the performance of traditional linear design and nonlinear design under the same working conditions, it is found that the latter has superior stability and response speed in dealing with complex dynamic environment. Moreover, this study also innovatively proposed an optimized design method based on nonlinear dynamics, which can effectively reduce the vibration amplitude of the system and improve the working efficiency and service life of the mechanical system.
