This article according to the characteristics of Sanshou, discusses bio-physical laws of hit-strength and gives some effictive methods-how to improve the hit-strength of Sanshou.

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.
