摘要
摩擦现象在日常生活中随处可见,在工业界中,有时需要减小摩擦,有时需要利用摩擦。关注一类非线性动力系统中自激振动的sprag-slip现象。根据前人的简化机械模型,考虑不同的系统参数对该现象的影响,设计出一套满足实验需要的装置。在完备实验装置的基础上,通过测量对不同系统参数下的sprag-slip现象的稳定性进行初探。
Friction phenomena exist everywhere in daily life. In engineering practice, friction phenomena are harmful and need to be reduced, or beneficial and need to be applied. In this paper, the author＇s attention was focused on sprag-slip phenomenon in self-induced vibration in nonlinear dynamic system. Referring to the works of simplified mechanical models by J.J. Sinou, F. Thouverez, and L. Jezequel [ 1 ] , the author designed and fabricated the experimental equipment for studying the sprag-slip phenomenon. In the experiment design, some system factors, which may have different influences on sprag-slip phenomenon, were taken into account to satisfy the requirement of the experiments. Having finished the experiment design, the author presented some elementary work for stability analysis of the sprag-slip phenomenon according to the measurement data under different system parameters.
