Applying information technologies to a bulldozer design

Abstract

An analysis of the application of information technology in transport and technological machines is presented. The features of the use of information technology in the design and operation of transport equipment are given. The objectives of applying information technology at the stage of machine design are determined. The information model of the bulldozer is presented as the system comprising external environment – working equipment – caterpillar track - frame - transmission - engine - operator. A dynamic model of the bulldozer has been developed. Mathematical models of the elements of the dynamic model are presented. Also, characteristics are given which reflect the processes occurring during technological operations when using the bulldozer for carrying out excavation works. It has been established that the information model of the bulldozer makes it possible to obtain data to calculate loading of the bulldozer elements and to optimize selection of the best machine parameters at the stage of functional design.
