The new method of check for temperature's rise BX1 arc welding transformer is advanced according to principle that the generating and radiating of heat at the arc welding transformer are the same under heat balance condition.

Study on the method of intensity checking of shafts with FEA;

Based on its static,dynamic analysis and dynamic intensity checking,stress and displacement distribution as well as dynamic response of the whole system and its important components are obtained.

This paper analyzes the characteristic of non standard hydraulic cylinders, discourses upon the general scheme of the CAD of non standard hydraulic cylinders, and emphasizes on discussing the implementing method of the dimension driving module and intensity checking module.

Study on strength checking data model for pump parts;

The Date-base system of pipe flange achieve the inquiring and strength checking of date about national standard pipe flange,and optimize the flange s dimensions if satisfied strength, and achieve the batch strength checking of FEA in Date-bas

Strength calculation and checking of key pumps parts have great effects on performance and lifespan of complete machines, conventional methods of strength checking could hardly meet the demands in design precision and efficiency.
