Some points of trimming and piercing die design for the friction press,such as the structure mode selection of the die,control of strike force,the size design of strike block,position of upper and lower die and related notices,etc.

Measuring method for hitting energy and hitting power of screw press;

This article based on the elastic-viscoplastic behavior of the forging,presented its elastic-viscoplastic model and its own constitutive relation,with these established the dynamic mechanics model of the hydraulic forging hammer,and also calculated the mathematics analytic equation of the hitting power.

To study the integrated decision-making of the fire and electronic warfare in the single to multiple attack,the target sequencing algorithm of the fire attack is put forward by considering the effectiveness of the jamming system.

By analyzing the factors which influence on digital tank company’s fire strike capability, an evaluating index system is built up in the paper.

Aiming at the security of equipment materials distribution center in the war,the paper discusses the influence factors of addressing model of equipment materials distribution center under condition of modern war,proposes the least cost and the shortest time addressing model of equipment materials distribution center based on fire strike.
