Dynamic analysis of connecting rod of piston machine used in oil industry

A.I. Ismayil - Azerbaijan Technical University

The paper analyzes the stress and deformations for the connecting rod made of steel materialor special cast iron by applying pressure on it in structural analysis, performed on ANSYS software. The analysis of static stress and damages due to the application of pressure is presented and analyzed. Reviewing the analysis results, we can decide whether our designed connecting rod is safe or not under applied load conditions. Investigation of complex problems with respect to friction and wear (clearances), stresses and strains phenomena in connecting rod of piston machines allows to solve the problems of increasing the durability of these machines.
