摘要

组装ESP32开发板和超声波测距传感器，让装有Phyphox 软件的智能手机通过蓝牙接收传感器的信号，研究弹簧振子在气垫导轨上做阻尼运动中不同挡板面积对阻尼系数的影响。实验结果显示，阻尼系数与挡板面积呈线性关系。

Abstract:

The influence of different baffle with different areas on the resistance coefficient was studied when the spring oscillator moved on the air cushion guide rail by the assembled ESP32 and ultrasonic distance sensor and the smartphone with APP of Phyphox．The measured date was transferred via Bluetooth to smartphone．The experimental result shows that the resistance coefficient has a linear relationship with the baffle area．

Key words: Phyphox smartphone resistance coefficient spring oscillator
