摘　　要：设计了振动与声课程可视化教学平台,包含了振动问题、声场问题和特殊函数三个模块,每个模块包含了若干具体可视化内容的子模块。具有友好人机交互界面的可视化教学平台,把抽象的振动与声的物理规律和现象进行形象化演示。以"单自由度阻尼振动系统受迫振动"、"组合声源辐射声场"、"柱函数"三个子模块为例,介绍了动态和静态的可视化结果。The visual teaching platform of foundation of sound and vibration is designed,which includes three modules:vibration problem,sound field problem and special function. Each module contains several sub-modules of specific visual content. The visual teaching platform with friendly human-computer interaction interface demonstrates the abstract physical laws and phenomena of vibration and sound visually. The dynamic and static visualization results are introduced by taking the three sub-modules of forced vibration of single-degree-of-freedom damped vibration system,and radiated sound field of combined sound source and cylinder function as examples.
