摘要
在实验中,以受间隙约束的悬臂梁系统为模型,对该系统在简谐激励下存在的各种非线性动态响应状态进行了定性的研究,并利用Matlab软件对实验数据进行处理,绘制出相图。通过分析,得出不同的响应状态随系统参数变化的演变规律,为理论研究提供实验依据,从而促进非线性振动理论的发展。
Based on a model of a cantilever beam system with clearance restriction,its nonlinear dynamic response to harmonic excitation are studied qualitatively in experiments.Using Matlab software,the experimental data are dealt with and phase figures are drawn.Through analysis,the evolutional law of its responses with varying of the system parameters is clarified and the results offer experimental proofs for development of theory of non-linear oscillation.
