Comparative analysis of the operational properties of Belarusian-Russian and Chinese tractors
The article assesses the impact of ballasting on the performance of the machine-tractor unit (MTU), on fuel consumption, and calculations are made on the formation of the MTU to perform the technological operation of cultivation. In recent years, tractors manufactured in Southeast Asia, including Chinese manufacturers, have begun to appear on the Russian market, in particular, tractors of a universal-row class with engine power from 90 to 160 hp. (66-118 kW). These tractors directly compete with Belarusian-made tractors of a similar traction class. In this study, a comparative analysis of the operational properties of tractors of the Belarus family and the Chinese company Zoomlion is carried out. The operational properties are considered through the use of ballast and the effect of ballasting on the traction properties of tractors. Ballasting versions are proposed, rated traction forces are calculated at different versions of loading, as well as traction forces at different operating gears at different versions of loading. For comparison, the technological operation "cultivation" is chosen with the corresponding initial data for calculations. An index method is used to determine the optimal loading option at which the best performance is achieved.
