Innovative local water evaporating air cooler intended for tractor cabs
摘要
Design of innovative water evaporating air cooler intended for normalization of tractor-driver’s thermal condition by means of local airflow supply is proposed. The apparatus can be used both on new tractor models and on models under service, where air coolers are absent.

Evaluation of the impact of wheel tractor velocity and other factors on its oscillations
摘要
Vertical oscillations of tractor Т-150К during operation on sandy soddy-podzolic soil prepared to sowing were investigated. As result of calculations carried out using experimental data on viscoelastic soil properties, the influence of a tractor velocity on appearance of mutually independent oscillations of its axes was shown.

Wear investigations of working parts of machines and technological equipment
摘要
Wear pattern on the working surfaces of concrete mixer blades can be explained mainly by change of mix pressure on different points of working edge. The rotating blade angled to the rotation plane moves the mix both to direction of moving and along the concrete mixer axe. When high abrasive mixes of different fraction composition are prepared, wear of the working surfaces on thickness results in deflection, deformation and destruction of the blade.

Results of the exhibition Agritechnica-2013
摘要
В Ганновере (Германия) с 10 по 16 ноября 2013 г. проводилась крупнейшая международная выставка сельхозтехники Agritechnica-2013. Организатор выставки, Немецкое сельскохозяйственное общество DLG, отмечает успех посещаемости: в 2013 г. в выставке приняло участие около 2900 экспонентов, в том числе рекордное количество иностранных – более 1500 из 47 стран. Численность участников на 7% превысила показатель предыдущей выставки (также почти на 11%, до 42 га, увеличилась выставочная площадь). Данный результат подчеркивает огромный интерес со стороны сельхозпроизводителей, подрядных предприятий и организаций по продаже сельхозтехники.
