SIMULATION-ANALYTICAL ANALYSIS OF THE INFLUENCE OF TECHNOLOGICAL FACTORS ON THE STRESS-STRAIN BEHAVIOR OF FUNCTIONAL SURFACES OF MOLD PARTS

In contemporary mechanical engineering, manufacturing various parts of dies, molds, etc., is particularly challenging. This is due to some factors, including the high precision of the components, the low roughness of their functional surfaces, significant temperature fluctuations during operation, the complex nature of the materials used in these parts, and the high frequency and intensity of the cyclic and alternating thermal and power loads.

Influence of Technological Factors and Cutting Tool Geometry on the Machinability of Chrome-Nickel Steels and Alloys

Statement of the problem and purpose of the work. The technology of machining hard-to-machine materials, which undoubtedly include high-alloy steels and chromium and nickel-based alloys, has some advantages over traditional abrasive machining methods. Among the most significant advantages, researchers note greater flexibility, faster changeover to other types of parts, the ability to combine several operations into one due to the versatility of the forming motion of the blade tool compared to the abrasive, higher productivity, and relatively low technological cost.

DESIGN AND ANALYSIS OF THE OVERHEAD CRANE WITH SIX VERTICAL COLUMNS

This study delves into the comprehensive examination of an overhead crane's construction, focusing on its frame, columns, and beams, while considering factors such as strength, stability, and stiffness. Through an in-depth review in the design domain, it is proposed a specific structural configuration for the overhead crane. This design comprises six vertical columns supporting two longitudinal beams equipped with tracks for the trolley's longitudinal movement. Additionally, cross beams featuring winches are mounted on the trolley's cross beams.

Minimization of public transport delays at arterial streets with coordinated motion

Research results, using which the method of minimization of public transport delay is improved at intersections with the system of coordinated motion control, are given in this paper. Such transport research was carried out with simultaneous application of field measurements of the study of traffic flow indicators and computer simulation in PTV VISSIM to check the level of efficiency of coordinated control and the reliability of the results.

Investigation of the Carbide-tipped Tool Wear Hardened by Method of Aerodynamic Impact

Theoretical calculations and experimental studies of the influence of wear on the cutting process and the precision parameters of machining by hard alloys during milling are described in the article. The method of aerodynamic hardening is designed to increase the durability of tools, which are heterogeneous compositions of tungsten carbides, titanium and tantalum with cobalt ligature operating under severe process conditions with varying impact loads.
