Introduction. The article analyzes the microclimate parameters (temperature, speed and air pressure) in the metallurgical crane cabin provided by the air conditioning system using the finite element method integrated into the ANSYS software package. The metallurgical crane cabin air conditioning system was selected based on the engineering calculation of the required air flow rate supply, taking into account factors that affect the system performance, such as the location of the equipment and the degree of its dustiness. Problem Statement. The purpose of this research was to check the efficiency of the air conditioning system of the metallurgical crane cabin, which was selected based on the results of the engineering calculations. Theoretical Part. In the main part of the research, the distribution fields of temperature, speed and air pressure inside the cabin of a metallurgical crane were constructed, the values at the points of which were compared with the hygienic standards. In addition, the factors that affect the adequacy of the developed model were considered, namely the grid structure, the way to set the initial and boundary conditions. Conclusion. The refinement of the analysis grid and the consideration of infiltration in the model eventually allowed us to get more correct results: the temperature at the characteristic points differ by no more than 1.3 °C, the speed values do not exceed the standard 0.3 m/s, the average normalized temperature of 24 °C is maintained in a volume of about 60-70 % of the total cabin volume.

To research the load upper bracket of Francis hydroelectric unit, then established the finite-element model, and analyzed the structure stress of 7 operating condition points with the ANSYS software. By the strain rosette test, acquired the data of stress-strain in the area of stress concentration of the upper bracket. The inaccuracy was considered below 5% by analyzing the contradistinction between the finite-element analysis and the test, and match the engineering precision and the test was reliable. The finite-element method could be used to judge the stress of the upper bracket, and it could provide reference for the Structural optimization and improvement too.

Abstract The paper describes the intention of the authors to determine whether it is possible to predict relative belt edge endurance for radial passenger car tires using the finite element method. Three groups of tires with different belt edge configurations were tested on a fleet test in an attempt to validate predictions from the finite element results. A two-dimensional, axisymmetric finite element analysis was first used to determine if the results from such an analysis, with emphasis on the shear deformations between the belts, could be used to predict a relative ranking for belt edge endurance. It is shown that such an analysis can lead to erroneous conclusions. A three-dimensional analysis in which tires are modeled under free rotation and static vertical loading was performed next. This approach resulted in an improvement in the quality of the correlations. The differences in the predicted values of various stress analysis parameters for the three belt edge configurations are studied and their implication on predicting belt edge endurance is discussed.

Element Method

Abstract The finite element method has been used widely in tire engineering. Most tire simulations using the finite element method are static analyses, because tires are very complex nonlinear structures. Recently, transient phenomena have been studied with explicit finite element analysis codes. In this paper, the authors demonstrate the feasibility of tire cornering simulation using an explicit finite element code, PAM-SHOCK. First, we propose the cornering simulation using the explicit finite element analysis code. To demonstrate the efficiency of the proposed simulation, computed cornering forces for a 175SR14 tire are compared with experimental results from an MTS Flat-Trac Tire Test System. The computed cornering forces agree well with experimental results. After that, parametric studies are conducted by using the proposed simulation.

According to the situation that the dual-friction drums on the new type towing machine lack stress analysis when designed, the safety is difficult to test and verify. The pull of wire rope in various positions was derived and calculated, so both compressive stress and tangent friction force generated by the pull of wire rope were calculated. The result made by ANSYS software demonstrates the safety of the left drum which suffers from larger loads, structure improvement measures are put forward for the drum.
