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(Oscilla-ting 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.
MECHANICAL ANALYSIS OF THE PHENOMENON OF AMPLITUDE INCREASE WHEN SCREWS SLIDE DOWN A SLOPE
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 rea-son for the increase in oscillation amplitude is explained through force analysis during the slid-ing process and verifies it through experiments.In addition,simulation software is used to ex-plore the effects of different parameters on the motion through simulation.
