查询词典 transverse section

Based on the above theories, some vibration characteristics of longitudinal acoustic horns are analyzed with finite element analysis software ANSYS. Some factors influence to large end amplitude distribution is studied such as big end diameter, length of horn, and diameter ratio of big end to small one. In addition, we carry on analysis and research to resonance frequency of large cross-section acoustic horn, amplitude magnification factor, wave node position of horn, transverse vibration situation and so on, and some related change rules are obtained.
