За 10 месяцев 2011 года ОАО «Курганмашзавод» увеличил объемы выпуска гражданской продукции в два раза по сравнению с аналогичным периодом 2010-го. Основной прирост выпуска гражданской продукции дали вездеходы ЧЕТРА ТМ130. Объем их выпуска увеличился почти в 3 раза.

The new art-design look of frame-panel cab system for serial and prospective «Kharkov tractor plant» production is designed.

Some results of analysis of opportunities to rise a fuel affordability of diesel 6Ch 11/12.5 by regimes of low load or idling by deactivating some cylinders or cycles, named in other words as method of transformation of diesel active volume are presented. This analysis is carried out with the use of experimental universal diesel characteristics, namely fuel specific consumption of diesel, and mathematical simulation of some regimes of diesel operation.

An automatic two-channel control system of module with electromechanical transmission including power channel and technological channel is offered. Authors have also analyzed the factors that influence on power inputs at the cutting of herbage during the work of a segment-finger mower with electromechanical drive. An algorithm for calculation of resistance by segment-manual mower operation, which takes into account power consumption for the fluctuations of twisting moment and angular speed is given.

The influence of planetary muff gear ratio on the rigidity of pneumohydraulic elastic element has been analyzed.

A method of optimal aggregation of basic machines (tractors) and working construction equipment is proposed. System analysis, statistic technometry and economic-mathematical computer simulation are fundamental in this methodology.

The results of tiller hoe shape optimization are presented. These findings were used for the production of working organs of the subsurface ploughs, allowing to achieve the best soil cultivation.

An integrated system of quality control for mechanized works in crop growing is developed. The block schematic diagram and engineering tools for these purposes are described.

Traffic safety mainly depends on the reliability of metal-ceramic friction materials used in brake gears, the most important vehicle units. The results of friction disk trials tested in actual condition immediately on the assembly are presented.

The general approach to forecasting of optimum values of operational indicators of the agricultural machine-tractor aggregate for the specified operating conditions is considered. As an example of its realization for the concrete unit the balanced system of operational indicators received as a result, their values, optimum levels of loading and use degree are given.
