Structural Analysis and Study of Self-Adjusting Mechanisms

Konstantin Ivanov

The self-adjusting mechanism, as the study shows, independently (without a control system) adapts to changes in the working process, which significantly expands the possibilities of its use in automatic machines. The main idea of creating a self-adjusting mechanism is to use a …

Radio-Quality-Aware Model Predictive Control for Industrial Wireless Control Networks

Anar Khabay, Akerke Baurzhan, Аmandyk Tuleshov, Moldir Kuatova et autres

Industrial wireless sensor and actuator networks are increasingly used in closed-loop control systems. In such systems, packet dropout, channel degradation, and communication delay can deteriorate tracking performance. This paper proposes a Radio-Quality-Aware Model Predictive Control (MPC) strategy for an industrial conveyor drive …

Dynamic Modeling of the Anisotropic Non-Ideal Weakly Gyroscopic Rotor System

Zharilkassin Iskakov, Aziz Kamal, Assylbek Jomartov

In this paper, the dynamic modeling of the anisotropic non-ideal weakly gyroscopic rotor system is considered. Equations of nonstationary transitions are derived from motion differential equations; then, the control equation, stationary frequency dependencies, and force and energy relations are obtained. When the …

Study of Microstructure and Binder Removal in an Additive-manufactured Composite Sample

Yerkebulan Tuleshov, Bauyrzhan Bazarbay, Assemgul Uderbayeva, Б. Ж. Кожагельдиев et autres

The application of a specially developed metal composite material using LDPE polymer as a binder in additive technology is described. Nitrogen environments can facilitate the formation of chromium nitride (Cr2N), particularly at temperatures between 500-600°C, adversely affecting the material's corrosion resistance. Following …

Rheological Transformation of Waxy Crude Oil During Transition to a Viscoplastic State

Uzak Zhapbasbayev, Timur Bekibayev, Gaukhar Ramazanova, Olzhas Kenzhaliev

This study investigates non-isothermal laminar flow of waxy crude oil in a pipe. Due to heat exchange with the surroundings, the flow cools along the pipe length, resulting in a gradual transformation of the oil rheology from Newtonian to viscoplastic behavior. The …
