The problem of synthesis of control algorithms for gear shift using electric-hydraulic and electronic devices
摘要
Approaches to the problem of synthesis of control algorithms for gear shift using electric-hydraulic and electronic devices were examined. It is noted that well-timed shift should increase tractor velocity and a “successful” algorithm should not worsen its usability. Possible criteria were analyzed.

Dynamic stability of a crawled tractor equipped with hydrovolumetric slewing mechanism when it is aggregated with a plough
摘要
Dynamic model of a crawled tractor equipped with hydrovolumetric slewing mechanism is substantiated. It was used to estimate the dynamic stability of this tractor aggregated with a plough. Effect of hydrovolumetric slewing mechanism application on the crawled tractor on its average pass velocity is estimated experimentally.
