对称间隙单自由度振动系统的Simulink仿真
|
摘要
根据对称间隙单自由度振动系统模型,通过Simulink模块库中的多种子模块,设计了一种在数学模型上与之等效的仿真模型。该模型由积分模块、非线性模块、输出模块构成,能够实现系统稳态响应相图的输出,结果与数值分析结果完全吻合。该方法为研究非线性系统的动力学行为提供了一种新的仿真方法。
On the basis of a single-DOF vibration system with symmetric gap,an simulation model with a full equivalent mathematical model was designed using various submodule in the module library of Simulink. The model consisted of integral module,nonlinear module,output module,can realize the output of the system steady-state response phase diagram,results accord with the results of numerical analysis. This method provides a new simulation method for studying the dynamic behavior of the nonlinear system.
