body stress
6.This paper analyzed the strength calculation performend on the PC-386 microcomputer using SUPERSAP software for wagon body which were exported to Botswana. Calculating models such as structure separation, constraint treatment, load treatment and calculating cases were given. The results showed that the stress of the BR Wagon body never exceeded the allowable stress values under various cases and satisfied the demands of ″railway wagon strength design and test standard″.
10.Structure design of large caliber ball valve above φ 500 mm caliber under middle pressure is introduced in detail, and strength calculation of valve body has been made according to ASMEⅧ code. The thickness of valve body is primarily determined by its rigidity. Stress and deformation analysis of ball body is made by ANSYS.
