The similarity rule and characteristic of shock in water about underwater and surface blasting were studied in underwater blasting domain,and the monitoring of shock in water and safety assessment to surrounding building were carried out at many national defence and hydropower projects,and abundant data and experience were accumulated.

Mathematical model is established to calculate the shock wave characteristics.

We use MSC Patran as preprocessing and postprocessing platforms to build the impact model for the liquid storage tank of a fuze and MSC Dytran as a solution-seeker to study the anti-impact characteristics and dynamic response of the liquid storage tank with different structures.

The paper presents a dynamic model of impact process based on the working condition of drilling pump valve,and analyzes its impact characteristics.

Based on the analysis of impact characteristics of coupler draft gears when railway vehicles are marshalling and coupling.

Measuring the shock characteristic of small wire-rope vibration isolators by hammering;

Experimental investigation on shock characteristic of wire rope isolator;

Considering the limitation of the shock experiment of a drop hammer,a shock simulation experiment platform is used to test the shock characteristics of isolators.
