Research Results

Theoretical research
Through years of in-depth research, abundant scientific research achievements have been obtained in terms of ship structural strength analysis and evaluation under air/water nuclear explosion conditions, ship structural strength analysis and evaluation under underwater and in-cabin explosion conditions, impact environment prediction for underwater explosion ship equipment, impact resistance design and evaluation of ship equipment system, and impact resistance prediction and evaluation of personnel and protective devices, and have been widely applied. In recent years,  We are also turning to the research in civil fields such as transportation/water conservancy projects, and mine/marine equipment.
Test technology
CSSRC always pays attention to the research and application of explosion test technology, and has two large explosion testing basins, floating impact platform, pressure tank for deep-water explosion test, door and window explosion test device, various impact machines, and other explosion test equipment, and has the ability to simulate underwater/air/in-cabin explosion and impact loads. CSSRC has successively undertaken explosion tests on hundreds of scale model, shock resistance assessment tests on more than 500 sets of ship equipment, dynamic performance tests on a large number of vibration isolation and shock resistance components, and other tests, detection and evaluation of abundant  products and models. At present, CSSRC has formed a database of underwater weapon and charge power, scale model and ship explosion tests, equipment shock resistance and damping component characteristics, which can be applied to the optimal design and analysis of weapon effect and ship explosion resistance.
Test Technology
CSSRC has nearly 500 dynamic parameter measuring instruments such as channel acceleration, velocity, displacement, strain, force, pressure and impact environment measuring instruments. CSSRC has the capability of developing underwater explosion pressure measurement and impact environment measurement system, and is the national third-class measuring organization of acceleration sensor measurement.
