Use of Special High-Rigidity Profiles in the Load-Bearing Systems of Tractors and Automobiles at the Magnitogorsk Metallurgical Combine

Abstract

Special reinforced profiles for the load-bearing systems of tractors and automobiles are likely to be in high demand in the future. They provide these systems the required strength and stiffness values, particularly in diagonal torsion. Preliminary tests have shown that the cab of the promising VT-200 tractor could be made from a certain combination of special reinforced profiles made at the Magnitogorsk Metallurgical Combine. In a first approximation, an element of the tractor-cab floor was developed and design studies were carried out. Analyses have shown that the proposed solution provides the required strength properties without increasing the estimated weight or dimensional characteristics while keeping manufacturability and costeffectiveness at acceptable levels.
