Розробка конструкції пневмо-шнекового транспортера та обґрунтування його параметрів

The paper presents the developed design of a research prototype of a pneumatic screw conveyor and the research methodology aimed at determining power characteristics for moving various types of loose materials depending on the influence of pressure and air volume. The dependences of pneumatic screw conveyor efficiency on the change in the area of a hopper hole, the rotation frequency of a screw feeder and the value of an operating air pressure in a technological line have been determined. The influence of the form and the geometrical parameters of a central replaceable nozzle on the distance of loose materials transportation has been determined

The impact of the kinematic parameters of bounce and pitch motions of sprung mass on wheeled vehicles handling

The impact of the kinematic parameters of bounce and pitch motions of wheeled vehicles’ (WVs’) sprung mass (SM) with non-linear power characteristics of the cushion system on vehicles handling is studied. The dependence of the critical value of the dynamic steering angle of directive wheels on the amplitude of bounce and pitch motions and the kinematic parameters of motion is developed. It is proven that the limit value of the dynamic steering angle of directive wheels is reduced during acceleration, and vice versa (it increases during braking, while the bounce and pitch motions are significantly reduced)

Обґрунтування раціональних параметрів живильника пневмошнекового транспортера

The article presents the justification of rational parameters of the operating parts of a pneumoconveyor screw. The dependences of pressure screw efficiency on the change in design and kinematic parameters and process variables of a screw and on loose material characteristics have been considered. In addition, general analysis of the choice substantiation of a feeder pressure screw diameter and the cross-sectional area of a hopper loading opening, which provides the required efficiency of a pneumoconveyor screw, has been conducted
