| contents | Virtual instrument technology has been increasingly used in university physics experiment teaching. An experimental platform is specifically constructed for studying low-frequency vibrations in university physics, which is based on a computer and its internal sound card, along with a program developed in LabVIEW programming environment to perform control and measurement on our experimental platform. The proposed platform effectively replaces the conventional signal generator and oscilloscope traditionally used in such experiments by integrating virtual instruments and essential experimental equipment. The platform offers various functionalities, such as synchronous transmission and reception of low-frequency signals, frequency measurement, dynamic frequency sweep measurement, and measurement using the three-point approximation method. The proposed platform has been successfully applied in experiments involving forced vibration, resonance of tuning forks, and dynamic measurement of Young's modulus. Unlike conventional low-frequency vibration experiments, the proposed experimental platform optimizes efficiency, reduces costs, and offers opportunities for enhancing the instructional content of experiments. Furthermore, the incorporation of state-of-the-art computer technology enhances students' engagement and enthusiasm for learning. |
