Tarasenko V.E., Belarusian State Agrarian Technical University, Minsk, the Republik of Belarus

The factors causing an overheat of a tractor diesel engine are considered. Process of heat exchange in system of cooling is analysed at a non-stationary temperature mode. It is offered to estimate an overheat of a diesel engine in factor of an overheat. The equation is presented, allowing to define an ambient temperature at which the stationary temperature mode of a diesel engine is provided. A number of the constructive decision promoting increase of a system effectiveness of cooling is offered.

A FORMING OF DUMP TRUCKS CHASSIS POWER LOADINGS

Ispenkov S.A., OJSC “BELAZ”, Zhodino, the Republik of Belarus

Rakitsky A.A., the Joint Institute of Mechanical Engineering of the NAS of Belarus, Minsk, the Republik of Belarus

The experimental determination problems of loads in BELAZ mining dump truck chassis are considered. Statistic analysis of field test data is carried out. Linear dependence of the suspension lateral forces is estimated and experiment-calculated method of the force assessment in the central spherical joint of front and rear conventional suspensions is proposed.

Algin V.B., the Joint Institute of Mechanical Engineering of the NAS of Belarus, Minsk, the Republic of Belarus

Sabaleuski A.K., the Belarusian National Technical University, Minsk, the Republic of Belarus

The scheme and the basic operations of a hybrid vehicle are presented. Technique of making output characteristic is developed for full-throttle acceleration modes: with charged and discharged battery. Results may be used for further analysis of traction-speed and fuel-economy parameters of a vehicle with а hybrid power unit.
