Energy Requirement Model for Combine Harvester, Part 2: Integration of Component Models

Research Status of Power Allocation of Combine Harvester

“…The combine harvester originated abroad, in order to improve the working performance of the harvester, foreign scholars have carried out a large number of theoretical and experimental studies on the speed, torque and other related parameters of various components in different working conditions, the research on torque parameters originated from the test of working torque of iron and steel rolling mill conducted by American scholar Sydenham [9] , with the widespread application of computers, the applicable scope of torque testing is gradually expanded, and the load testing research of agricultural machinery equipment is carried out accordingly. D.C. Baruah [10][11] believes that the harvesting and threshing process accounts for a large proportion of the power consumption of the combine harvester, combining crops, machines, soil and other parameters and using physics, mathematics and mechanics to establish the power con- established, the model shows that the amount of crops fed, the walking speed of the machine, the speed of the drum, and the load of the walking wheel are the main factors affecting the power consumption of the whole machine; through the multiple regression method, the values of the three model coefficients related to the main energy-consuming processes, such as threshing, traction and friction of moving parts, are evaluated. M.A.Pustigine [12] through a large number of experimental studies, discovered the components of harmful power consumption in threshing drum operation of combine harvester, It is mainly to overcome the friction power consumption of the bearing and overcome the air resistance power consumption, a calculation formula for harmful power consumption is proposed, and the resistance coefficient A value of the drum with rasp bars and the resistance coefficient B value of the drum with pins are determined.…”

Selection of proper combine harvesters to field conditions by an effective field capacity prediction model

“…Related topics have been studied by various researchers who developed mathematical models to predict combine harvester performance. Baruah and Panesar [16,17] predicted the power consumption of Indian combine harvesters for paddy and wheat varieties. Jarolmasjed et al [18] developed a mathematical model for header loss of the combine harvesters in Iran; the model had a 76% correlation coefficient.…”

Research on a Method of Evaluating Fuel Efficiency during Traveling and Driving for Head-feeding Combine Harvesters

“…D. C. Baruah et al (2005a) reported an energy demand model for each component of conventional combine harvesters, and conducted multiple regression analysis based on the results of harvesting tests with paddy rice and wheat using seven conventional combine harvesters (engine power: 29.0 kW-55.0 kW, drive system: wheel). Baruah et al (2005b) also associated the developed models. In the associated models, "frictional resistance at the horizontal bearing surface of a reciprocating knife due to its selfweight," "impact of the threshing cylinder on crop mass," and "tractive resistance due to self-weight of the combine harvester associated with parameters regarding the center of gravity position, wheel and soil cone index" were selected as the model coefficients.…”
