EFFICIENCY RISE OF FUNCTIONING OF MACHINE-AND-TRACTOR ASSEMBLIES (MTA) AT EXPENSE OF OPTIMIZATION OF OPERATING CONDITIONS AND OF DYNAMIC CHARACTERISTICS OF ENGINE-TRANSMISSION UNIT WITH WHEEL GEAR BY EXAMPLE OF T-170B TRACTOR

There the assessment technique of energetic characteristics of MTA has been improved; the change mechanisms of dynamic characteristics has been determined; the assessment of their influence of MTA characteristics has been given. The optimum characteristics and the operating conditions of MTA have been determined. The program of design and of assessment of MTA characteristics by computer has been developed. The optimum operating conditions of D-160 engine have been determined; they may be included at the technical normalizing of mechanized field-work, at the substantiation of operating-process requirements for the new types of tractors. The improved techniques and the optimum operating conditions of D-160 engine have been introduced in the North-West Branch of Research Motor-and-Tractor InstituteAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
