摘要: 本文采用数值解析法研究了非线性因素对传动系统动力总成双质量飞轮扭振减振器动态性能的影响。首先，分析了双质量飞轮的结构和工作原理，建立了双质量飞轮的非线性动力学模型，然后采用拉格朗日法建立其运动方程。然后，使用分岔图以及相图等方法对其进行研究，通过选取刚度幅值、阻尼系数、等效惯性比等几个非线性参数进行分析。结果表明，非线性动力学分析方法适用于双质量飞轮的非线性扭转振动分析，同时减小刚度幅值、增大阻尼系数或适当增大等效惯性比均可有效减小双质量飞轮非线性动力学混沌区域，系统动力学行为也渐渐的变得简单，系统产生的振动和噪声也渐渐降低，可有效提高系统的使用寿命。
Abstract: This paper employs the numerical method to study the effect of nonlinear factors on the dynamic performance of the torsional vibration damper of the dual-mass flywheel in the powertrain system. Initially, the structure and operating principle of the dual-mass flywheel are analyzed, and a nonlinear dynamic model of the dual-mass flywheel is established. Subsequently, the frequency response equation is obtained using the averaging method. Finally, bifurcation diagrams and phase diagrams are used to study the system. By selecting several nonlinear parameters such as the amplitude of stiffness, damping coefficient, and equivalent inertia ratio for analysis, the results indicate that the averaging method is applicable for nonlinear vibration analysis of dual-mass flywheels. Additionally, reducing the amplitude of stiffness, increasing the damping coefficient, or appropriately increasing the equivalent inertia ratio can effectively reduce the chaotic region of the dual-mass flywheel’s nonlinear dynamics. The dynamic behavior of the system gradually becomes simpler, and the vibrations and noise generated by the system also gradually decrease, which can effectively improve the service life of the system.
