Abstract

For the study and experimentation of physical systems, it is essential to measure the physical variables, which implies choosing the most convenient method that does not affect the natural behavior of the system. This work presents the modeling and sensing of the spherical pendulum, integrating a novel non-invasive measurement scheme based on infrared sensors arranged in a quadrature configuration. The proposed method enables the estimation of angles around two axes, leveraging light reflection on a perpendicular plane aligned with the pendulum bar. A mathematical model was developed to create simulations, and a prototype was constructed to perform experiments and validate the detection method. The values recorded by the sensors enable the reproduction of the pendulum's trajectory, allowing for the correlation of real results with those of the simulations. The similarity of behavior between the simulations and the experimentation facilitates the validation of the proposal.

摘要

对于物理系统的研究和实验而言，测量物理变量至关重要，这意味着要选择最便捷且不影响系统自然行为的方法。本文介绍了球形摆的建模与传感，集成了一种基于以正交配置排列的红外传感器的新型非侵入式测量方案。所提出的方法能够利用与摆杆对齐的垂直平面上的光反射来估计围绕两个轴的角度。开发了一个数学模型来进行模拟，并构建了一个原型来进行实验并验证检测方法。传感器记录的值能够再现摆的轨迹，从而使实际结果与模拟结果相关联。模拟与实验之间行为的相似性有助于对该方案进行验证。
