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.

Many power transmission projects in western region of China pass through the permafrost with frequent thunders, so understanding the impulse characteristics of frozen soil is the basis of lightning protection of power transmission projects.

In order to find the correct impulse characteristics of the grounding grids systematically and factually,impulse grounding experiments are carried out by employing impulse current generator in uniform and two-layer soils which is based on principle of dimension similarity.

The power system and buildings’lightning protection are very important, and the performance of the grounding system directly impact the effect of lightning protection’the study of the lighting impulse characteristics of grounding electrode has the very vital significance for better anti-thunder.
