摘要: 研究开发了基于手机加速度传感器的竖直方向弹簧振子实验.使手机随着弹簧振子上下振动,利用手机加速度传感器软件得到弹簧振子做简谐振动以及阻尼振动的加速度变化图像.通过分析简谐振动加速度变化图象得出弹簧劲度系数、重力加速度;通过分析阻尼振动加速度变化图像得出弹簧振子做阻尼振动的加速度方程.

关键词: 手机加速度传感器, 简谐振动, 阻尼振动

Abstract: A physics experiment on spring oscillation using a mobile phone acceleration sensor is developed.The mobile phone is connected to a fixed end by a spring and oscillated after receiving an upward push. Acceleration graphs for the case of simple and damped harmonic oscillations are got. Results for the spring constant,acceleration due to gravity and a formula for damped harmonic oscillation are obtained according to the graphs.

Key words: mobile phone acceleration sensor, simple harmonic oscillation, damped harmonic oscillation
