Experimental research tillage machine and tractor aggregate
Abstract
The results of experimental studies of tilther MTU as part of MTZ-3022 and chisel plow. The main criteria for the effectiveness of tractors for agricultural purposes is a traction power or tractive efficiency. Efforts corresponding to maximum traction power or tractive efficiency is optimal, and the tractor work so hard to provide him maximum performance and fuel ekonomichnist.Chislennymi studies have established the effect of skidding tractor wheels on the operational and technological performance of the machine-tractor unit (MTU): lower performance and permeability, increased specific fuel consumption, tire wear; negative impact on the physical and biological properties of the soil (deviation from the optimum soil characteristics such as hardness, porosity, structure, density). The main causes of slipping wheels are fluctuations in the traction load of MTU and resistance force of its movement. According to several criteria: a trailer towing quality, energy costs and slipping soil quality indicators, the value is determined by the maximum allowable slippage. Its valid values for these criteria are different, so the determination of the slippage of the tractor is quite a challenge, not a single solution and requires studying the interaction of propulsion with the ground. Improvement and radical improvement of the material and technical base of the agricultural enterprises of various forms of economic activity will contribute to the successful implementation of tasks to increase production of crop and livestock production, improvement of its quality, increase productivity in agriculture. The measuring system allows to determine the slip, the rotational speed of the wheels, the crankshaft of the engine and shaft picking power, fuel, steering angle, angle breaking half-frames of the tractor or the rotation angle of the steered wheels, current position on the MTU and the actual speed.
