Science intensive technologies in manufacturing cast stops unified with structure of freight car center sill with axial load 27tp

Abstract

To solve the problem of manufacturing fright cars with increased carrying capacity and reliability it is offered to use in their design a center sill with a new type of a cantilever part created on the basis of a cast part of front and back unified stops. Special requirements to the characteristics of a cast part defined a necessity to develop techniques for its manufacturing with the aid of science intensive experiments and current methods of the computer analysis. The work is devoted to the description of methods and technological developments allowing the support of manufacturing a complex and significant cast part. The design of casting technology was carried out with the use of computer simulation. To ensure high wear-resistance of a body center plate there was developed a technology of hardening with high frequency current on the basis of computations and full-scale experiments.
