摘要
机械系统内部或边界间隙引起的碰撞振动是机械动力学的研究热点之一。该领域的近期研究成果有:(1)碰撞振动的间断和连续分析,包括稳定性分析、奇异性问题、擦边诱发分叉、非线性模态等研究;(2)碰撞振动控制,特别是不连续系统的控制方法和控制混沌碰撞振动;(3)碰撞振动分析的数值方法;(4)碰撞振动实验研究。
The vibro-impact of mechanical systems with clearances inside or on boundaries has received great attention over the past decade. This review surveys the recent advances in studying the vibro-impacts of mechanical systems in the following four aspects: (1) discontinuous and continuous analyses of nonlinear dynamics of vibro-impacts, including its stability analysis, singularity problems, grazing bifurcations and nonlinear modes; (2) control of vibro-impacts, especially various strategies for controlling discontinuous systems and chaotic vibro-impacts; (3) numerical analysis of impacts and vibro-impacts; (4) experimental studies on vibro-impacts. Finally, some open problems in further study are addressed.
