- Relationship between jointed slab and void of elastic foundation and acoustic features of resonator is studied by acoustic vibration.
- Piping vibration or damage caused due to dynamic loads, such as mechanical vibration, acoustic vibration, fluid hammer, pulsation and relief valve discharge.
- The environmental tes ting ,specification,and analytic evaluation for full size spacecrafts or lau nch vehicles in acoustic vibration,separation shock and random vibration,as well as component testing and specification are emphasized.
- The range and size of void,detected by acoustic vibration,prove to be closely associated with the acoustics features.
- Soft material damps down vibrations.
- characteristic length of acoustic vibration
