At first,existing two groups of strength checking formulae are listed to expose the differences between them.

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.

Shear strength check for a large oil tanker;

Development and Applications of the Strength Check System of Rotary Machinery;

An investigation is made in the aspect of strength check of the casing string in a high pressure gas injection well altered from water injection well.

An intellectualized system for strength verification and geometrical modeling of commonly used parts is realized;Under the VC environment,architecture of the system is presented based on CAA RADE platform.

The relationship between the strength and the composed materials was established,and strength formula of SCC with FA was founded.

To achieve this, the strength formula must be set up.
