DERIVATION AND ANALYSIS OF THE DYNAMIC EQUATIONS OF MOBILE ROBOTS WITH RANDOM DISTURBING FORCES BASED ON THE PRINCIPLE OF LEAST GAUSS FORCE

PDF https://doi.org/10.53939/15605655/2022_4_25 Tuleshov А.К., Seidakhmet A.Zh., Abduraimov A.E., Kamal A.N. Abstract. In this paper, the derivation of the equations of dynamics of a four-wheeled mobile robot is carried out using the variational principle of least constraint, known as the Gauss principle. Equations of nonholonomic constraints are obtained. The function of the measure of coercion of the…

Features of extinguishing fires in the oil and gas industry by feeding foam into a layer of flammable liquid

PDF https://doi.org/10.53939/15605655/2022_3_76 Uzenbekov Sh.B., Shapalov Sh.K., Abdeshev K.B. Resume. This article describes a method for extinguishing fires of oil and petroleum products in vertical steel tanks by feeding foam to form a low-layer film directly into the fuel layer at the bottom of the tank. The problems of extinguishing fires in tanks with a floating…

Problems of production waste efficient use in the metallurgical industry

PDF https://doi.org/10.53939/15605655/2022_3_46 Temirbaeva G.R., Ukibaeva G.K. Abstract: The active economy development, the increase in production growth rates led to the attraction of raw materials, fuel and energy resources to production. Due to the fact that natural resources are not infinite, their use should be improved through effective processing. But the low level of technology introduction…

Zoning of quarry and mine fields according to categories of drillability and explosiveness, in order to reduce the cost of drilling and blasting by 20% or more

PDF https://doi.org/10.53939/15605655/2022_3_9 Igizbaev R.K., Igizbaev M.K., Igizbaev K.B., Mager A.N. Abstract. Mathematical models (theory) have been developed, surfaces of the lowest values of the criteria for drillability and explosibility of ores and rocks of curvilinear-anisotropic rock massifs of ore deposits, and a method for zoning quarry and mine fields by categories of drillability and explosibility….

Capillary-keuekti zhyelerdegi zhylu almasudy experimenttik zertteu

PDF https://doi.org/10.53939/15605655/2022_2_42 Genbach A.A., Dzhamankulova N.O. Abstract: A porous cooling system has been studied, in which the coolant is supplied under the combined action of capillary and gravitational forces. A capillary-porous cooling system is proposed that simulates a caisson, in which heat transfer processes occur by vaporization of liquid in porous structures. The results of experimental studies…
