String module cultivator for surface tillage

Rudenko N.Y., Kayvanov S.D., Kalugin D.S., Zavyalik F.N.

Abstract

A string modular cultivator has been developed. It provides surface tillage at the depth of 0,02-0,03 m. Such tillage is necessary before sowing small-seeded crops such as beet, rapeseed, onion, carrot, tomato and so on. The cultivator can be used in cultivation of fallow lands because it ensures soil moisture preservation and prevents bringing of moist soil to the surface.

Estimation of use efficiency of automatic transmission of «torque converter - coupling - gearbox» type

Kotiyev G.O., Vasilyev V.V., Gorbatovskiy A.V.

Abstract

The paper describes a mathematical model for wheeled vehicle with automatic transmission of «torque converter - coupling - gearbox» type. In order to compare this type of transmission and mechanical one with same number of gears and ratios, optimal characteristics of torque converter for considered vehicle are selected. The paper presents the results of simulation of wheeled vehicle moving for both variants of gearbox in conditions involving variable resistance and moving velocity assigned by driver. Efficiency of hydromechanical transmission use is estimated.
