General<\/th>Based on the Application example #71, the acoustic analysis is performed.
Stress transient analysis and acoustic transient analysis are coupled.
The sound pressure distribution in the air over time is calculated.<\/th><\/tr><\/thead>
Analysis Model<\/td>For boundary condition, the force applied by the striking bar is set as a changing load over time.
The vibration of bell is analyzed by the stress solver, and the sound pressure in the air is analyzed by the acoustic solver.<\/td><\/tr>
Result<\/td>Depending on the sitiffness of the striking bar (Hard Strike and Soft Strike), the bell deforms differently and affects the sound pressure distribution in the air.<\/td><\/tr>
