摘　　要：本文从动力学角度,对2023年国际青年物理学家锦标赛的第9题“摆动螺丝(Oscillating Screw)”进行了理论分析和实验探究。该问题描述了在斜坡上释放一个螺丝钉,螺丝钉沿着斜坡向下运动时可能会产生越来越大的振荡。本文通过下滑过程中的受力分析解释了振荡振幅增大的原因,并通过实验进行验证。另外,本文还利用仿真软件通过模拟仿真探究了不同参数对该运动的影响。This paper presents a theoretical analysis and experimental exploration of the 9th problem,“Oscillating Screw,”in the 2023 International Young Physicists'Tournament(IYPT)from a dynamic perspective.The problem describes the release of a screw on a slope,which may generate increasing oscillations as it moves down the slope.In this paper,the reason for the increase in oscillation amplitude is explained through force analysis during the sliding process and verifies it through experiments.In addition,simulation software is used to explore the effects of different parameters on the motion through simulation.
