The modern level of multifunction machines on combined rail-wheel motion and its future trends for use in Republic of Belarus transport forces and national economy enterprises has been considered. The constructions of combined rail-wheel motion mechanisms and characteristic of the chassis for their aggregation has been analysed. The possibility of creation on the chassis MAZ-630308 and Ш-406 «Belarus» with combined rail-wheel motion the power-hungry bearer of different equipment for the support and repair automobile and railway roads and its using as locomobile has been showed. Single has been viewed different variants of enlargement the technological possibilities of the combined rail-wheel motion machines by mounting various plug-in work equipment, mechanisms and systems which can raise the level of safety, mechanisation and automation of work.

DOMESTICALLY PRODUCED GRAIN HARVESTERS: PRIMARY TENDENCIES OF DEVELOPMENT

Dyuzhev A.A., State special design bureau on grain- and forage harvesters, Gomel, Belarus

The fundamental demands to perspective grain harvesters of the fifth generation distinguished with broad application of the automation means are considered. It is shown that the employment of complex board informational#controlling system including the electronic control and diagnostics of engine and main harvester aggregates, allows considerably to increase its service life and essentially to boost the working efficiency. The computer simulation of harvester perspective models has allowed reducing design period from 45 down to 30 months. With the purposes of high quality achievement the necessity of development of a standardized procedure of rational control by reliability at the all stages of harvester life cycle is expressed.
