Model Optimization of the Road Construction Machinery Active Working Elements, Operating in Permafrost

Abstract

When designing a railroad track it is necessary to take into account a range of different factors especially if the construction of the track is carried out in areas with adverse climatic conditions, which applies to the conditions of the Far North. During construction of a new roadbed in modern conditions track and road-building machines are widely used which have constantly increasing power and speed, and therefore factors of dynamic influence on active working bodies of machines change. The designs of road-building and track machines take into account various types of loads, including dynamic ones, necessary for modeling working bodies. In this case, the modeling process is considered one of the ways to predict and optimize the mechanical systems of track and construction machines, widely using full-fledged models used to obtain new data on the designed object.
