Testing the reliability of threshing unit is difficult and thus often neglected before harvesting season, which can result in breakdown maintenance during peak time difficult-to-access areas for sensor mounting. In this paper, vibration analysis condition combine harvester was performed by introducing bracket inaccessible locations. The Adash A4900 Vibrio M analyzer (Adash spol. s.r.o., Ostrava...

The paper presents the results of experimental and model tests transport dispersed fluid droplets forming a cloud aerosol in stream air ventilating selected section underground excavation. excavation for testing is part ventilation network Experimental Mine Barbara Central Mining Institute. For given environmental conditions, such as temperature, pressure, relative humidity, velocity air, distr...

While Computer-Aided Engineering (CAE) technology has revolutionized engineering analysis, design and research, its penetration into the undergraduate mechanical engineering curriculum has been limited. As a result, undergraduate students do not acquire a solid foundation in CAE technology that they can build upon during the course of their careers. Our pedagogical approach for integrating CAE ...

The paper presents results of multicriteria optimum design of an embedded rail structure (ERS). The optimality criteria are based on the requirements to railway tracks related to cost efficiency of the design, minimum noise emission and minimum wear of wheels and rails. The design variables comprise the material and geometry properties of ERS, namely elastic properties and volume of compound, s...

The active magnetic bearing (AMB) is an integral part of the industrial rotational machine. The paper deals with simulation study of three and four coil AMB utilizing Finite Element Method (FEM). This paper also presents how ANSYS software (Ver. 12.1) can be used to perform the magnetic field analysis in the AMB. This work reports ANSYS simulation for two different structure of AMB that uses th...

In this paper, performance of centrifugal pump as turbine (PAT) is investigated numerically. Three different specific speeds are considered and three pumps are designed using diagrams from catalogues and CFturbo V.9 software. Next, models are analyzed by Ansys CFX 16 software and results are compared with those of CFturbo software. Also, a mesh study analysis for one case is performed in order ...

The paper presents a boundary condition independent transient thermal network model generated by means of model order reduction methods. The order reduction is performed with MOR for ANSYS which is based on the Krylov subspace method via the Arnoldi algorithm. Subsystems such as a semiconductor device and the printed circuit board are modeled with ANSYS, separately. Then, these models are used ...
