Розроблений аналіз гідро-кінематичної схеми кульково-гвинтового гідропідсилювача. Даний
аналіз вміщує: опис об’єкта випробувань, устрій кульково-гвинтового гідропідсилювача, принцип дії
кульково-гвинтового гідропідсилювача, конструктивне виконання кульково-гвинтового
гідропідсилювача, аналіз гідро кінематичної схеми гідро підсилювача по забезпеченню стійкості при
роботі в перехідному режимі. Designed analysis of hydro - kinematic scheme ball- screw-steering. This analysis includes: a
description of the test object, the device ball-screw-steering, the principle of operation of ball screw steering,
type of ball screw steering, analysis of hydro-steering kinematic scheme to ensure stability when operating in
transition mode. Considerable time ball- screw-steering works in the transition regime. When rudder work on
rectilinear motion distributor ball-screw-steering accompanied variable values of the opening angle. This
changes the size and shape of the cross section of the flow of fluid that moves through the contours of the edges
of the distributor. The overall flow of the liquid in the pressure line is divided between several edges distributor
operating in parallel, so if such a scheme work distributor cavitation may occur (the destruction of the flow),
which is accompanied by self-oscillations of the hydraulic system.
It was a detailed analysis ball-screw-steering dynamics. On the basis of calculations and equations of
structural schemes defined a common transfer function for subsequent analysis in the dynamics. The resulting
equations have helped build the amplitude - frequency response and phase logarithmic frequency response.
