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.
