• Fluid-structurecoupling of high-speed vehicle during underwater launching process
• Maneuverability of new pattern vehicles in the underwater and surface navigation conditions
• Fluid-structure coupling of the large-scale flexible airship.
- High density laser driven platform
- High-speed impact platform for structures
- High-speed Impact Material Test System (HIMTS)
This platform dedicates to the research of some transient energy transformation process (high-speed deformation of material, laser shock peening and explosive underwater etc.). The high density laser is used as the driven sources which can generated a very high amplitude (up to 5 GPa) pressure pulses in very short time (about 20 ns). A variety of high spatial and temporal resolution test method including PVDF (Polyvinylidene Fluoride), PDV (Photonic Doppler Velocimetry) and high-speed camera etc is adopted to capture the transient process. The main experimental system includes:
• Laser shock peening system
• Dynamic material property system
• Underwater explosive system
