摘要: 近年来,虚拟仿真实验教学方式凭借其成本低、安全度高、灵活性强等优势越来越受到国内外高校的重视. 本文基 于有限元分析软件ANSYS 设计驻波管虚拟仿真实验方案,涵盖驻波比法、传递函数法和管道脉冲法三种实验方法,给出误差 和计算效率的对比分析结果,并提供用户图形界面( GUI) 和命令流两种操作方式. 此方案可弥补目前高校大学物理实验缺少 声学实验的不足,对大学物理虚拟仿真实验建设具有一定的参考价值.

Abstract: In recent years,virtual simulation experiment teaching has received more and more attention of colleges and universities both at home and abroad because of its low cost,high degree of safety and strong flexibility. A virtual simulation experiment of standing wave tube is designed based on a finite element analysis software ANSYS.Three experimental methods are involved,including standing wave ratio method,transfer function method and pipe pulse method. The contrastive analysis results of error and calculation efficiency are given. Two operating modes, graphical user interface ( GUI) and command flow are provided. This design can make up for the deficiency of acoustic experiments in physics experiments of college and has reference value for the construction of college physics virtual simulation experiment.

Key words: standing wave tube, virtual similation experiment, finite element
