NUMERICAL ANALYSIS OF SLIDING FRICTION COEFFICIENT AND THE NORMAL PRESSURE BETWEEN THE CABLE WIRE

positive pressure, provides a method and basis for the practical engineering of steel wire in the ultimate friction shear stress accurately, set up and stay cable as layered slipping model provides important parameters of bending stress analysis. From the numerical simulation method analyzes the positive pressure parallel wire between the start. This paper first parallel wire contact problem of two cables are analyzed with the classical theoretical solution and the FEM software ANSYS, to verify the

NUMERICAL MODELLING OF UNDERVENTILATED FIRE IN A COMPARTMENT

the two ceiling vents showed a significant variation depending on the location of vent [5]. When research fire extinguishing is examined, two parameters seem to have a prevailing impact. The first is the size of the vents and the second is the heat release rate [6]. CFD programs are used in issues related to fire in a compartment and in general fire engineering. Most often, scientists use the Fire Dynamic Simulator program and the Ansys Fluent program [7, 8, 9]. The paper presents numerical

WIND INFLUENCE ON A BUILDING WITH THE NATURAL SMOKE REMOVAL SYSTEM

affected by the wind impact under adverse ambient conditions. There are the features of the wind described in the first section of the paper. Next, the impact of the wind on a building is shown. Two wind speeds and two wind directions were considered. A building model in the extended computational domain was built. The model was solved with the use of Ansys Fluent. The distributions of dynamic pressure caused by the wind on different facades of the building were presented. The particular attention was

PERFORMANCE ASSESSMENT OF AIR CONDITIONING INSTALLATION IN MULTIFUNCTIONAL SPORTS HALL USING CFD SIMULATIONS

The purpose of the paper was testing of the air distribution system performance in the multifunctional hall. The numerical simulations of the airflows were made with the Ansys software. Three cases with two working modes of the installation were simulated: a large sport event with audience on the stalls, an exhibition with presentation boxes and an indoor ice rink. Direct results of the simulations and statistical data were analyzed. The results showed that for the ice rink and exhibition the

RESEARCH ON THERMAL CONDITIONS IN VENTILATED LARGE SPACE BUILDING

Abstract The aim of the paper was to verify whether it is possible to predict thermal indoor environment in an industrial facility, characterized by large cubature and significant heat sources using a computational fluid dynamics (CFD) technique. For this purpose, thermal imaging measurements were carried out to obtain boundary conditions, followed by numerical simulations of the airflow using the Ansys CFX software. Direct results of temperature and velocity distribution of air were analyzed

CANTILEVER BEAM BASED PIEZOELECTRIC ENERGY HARVESTER

powerful complement for theoretical and experimental method. This paper uses ANSYS to analyze the single piezoelectric cantilever in static analysis, model analysis, harmonic response analysis and mechanical-electrical coupling analysis. It analyzes the natural frequency and voltage effect from four aspects which are length to thickness ratio, length to width ratio, the substrate thickness to piezoelectric thickness ratio and seismic mass. Test and measurement for piezoelectric energy harvester is

Design of Temperature Sensitive Structure for Micromechanical Silicon Resonant Accelerometer

of the original accelerometer to ensure symmetry of the MSRA, as well as compares and selects the appropriate structure, fundamental frequency, and size. The ANSYS simulation is used to verify the rationality of the structure design. The MSRA is fabricated using the Deep Dry Silicon on Glass technique and packaged in metal shell, a measurement circuit is designed and a full temperature test is conducted. The results show that the resonant frequency of the temperature resonator is strongly

MODELLING OF THE AIRFLOW IN THE PASSENGER COACH

. This part of the passenger coach was named as “the coach” in the paper (Fig. 1). The overall dimensions of the coach were 10.6×2.6×2.5 m and the construction of the vehicle was symmetrical. The walls of the compartment were exterior except for the partition wall. There were six identical, double glazed windows on longitudinal walls. The original model was highly detailed and calculation time would be very long. Therefore, the model was simplified in software ANSYS CFX. Unnecessary elements, such as
