Design and optimization of a vacuum infusion technological process for hopper car fabrication using polymeric composite materials

Abstract

The total design cycle of a new 19-5167 hopper car with the body and roof made of polymeric composite materials is presented. The construction design, the development of the reinforcing filler circuit calculation, the finite-element analysis of the intensely strained state, the tests of the elementary samples and construction joints, as well as the optimization of the vacuum infusion are implemented by Science and Technology Test Center Ap-ATeK Dubna together with Skolkovo Institute of Science and Technology on request of the F.E. Dzerzhinskii Science and Production Corporation Uralvagonzavod.
