Application and assessment of multifunctional bio-impactor device;

Investigation of the Safety for Solid Rocket Motor under Mechanical Impact;

Based on thermo-viscoelasticity theory and dynamic finite element method,impact deformation of motor case and grain structure together with hot spot formation in grain were analyzed and calculated in combinition with crack friction hot spot micromodel of solid propellant under mechanical impact,and critical impact velocity which can cause high-temperature hot spot was determined.

Based on the special requirements of nuclear power plant containment,the security protection performances of nuclear power plant containment under exogenous events such as earthquake,aircraft impact and explosive loading were discussed.

The grinding efficiency of smooth roll and centrifugal impactor was researched through the milling test of eight_roller mill at same flow rate and different roll gap for C1A and C2A during processing.
