摘要

本文分析了发动机阻尼系统的非线性特性。首先研究了系统的稳定性，得到了系统的外斜轨道。其次，利用Melnikov方法得到混沌的临界值，并研究了参数对非线性的影响。最后验证了非线性阻尼系数是影响混沌阈值的主要影响因素。同时，本文还证明了随着曲轴半径的增大而产生混沌的可能性。非线性特性的研究可以为发动机阻尼系统的分析和优化设计提供理论依据。

The nonlinear behavior of engine damping system

The nonlinear behavior of engine damping system is analyzed in this paper. Stability of the system is firstly investigated and the hetrolinic orbit is obtained. Secondly, the critical value of chaos is gained by Melnikov method and the effects of parameters on nonlinearity are studied. Finally, the conclusion is validated that nonlinear damping coefficient is the main impact factor affecting chaotic threshold. Meanwhile, the possibility of chaos with the crankshaft radius increased is proved in this paper. The research on nonlinearity may supply theoretical bases for analysis and optimal design of engine damping systems.
