Simple Regression

This paper deals with face gear design. The goal is to propose a simple formula for predicting the width of the wheel as a function of the main design parameters. A specific software was used to achieve this goal. This numerical tool is able to simulate the geometry and the quasistatic loaded behavior of a face gear. The statistical method used for analyzing the influence of data is described: The design of experiments leads to a simple regression model taking into account the influential parameters and their couplings. In the last part of this paper, the results of the formulas are compared to those of the software and an optimal design is proposed based on the regression model.

Traction Power

At development of common concept of current collection for three-phase traction power supply system there is the need to select and substantiate main design parameters of catenary suspension. For this purpose, the authors have carried out analytical calculations and developed a numerical mathematical model that allows assessing catenary statics and it’s dynamics in interaction with current collector. On the basis of results of modeling, the authors have substantiated and selected all the required parameters. In particular, they have determined the permissible speed of trains and maximal length of catenary spans.

Aircraft Performance

The present work describes an aircraft design methodology that uses the wingspan and its mean aerodynamic chord as main design parameters. In the implemented tool, low fidelity models have been developed for the aerodynamics, stability, propulsion, weight, balance and flight performance. A Fortran® routine that calculates the aircraft performance for the user defined mission and vehicle’s performance requirements has been developed. In order to demonstrate this methodology, the results for a case study using the design specifications of the Air Cargo Challenge 2013 are shown.

Outlet Angle

The paper presents the results of theoretical research on the influence of the main design parameters on the optimum value of the nozzle outlet angle. The analysis was carried out for the stages with the disc and the drum rotors. The cascade losses were determined using Traupel’s and Bammert’s generalized cascade data. The calculations have proved that the blade height, the profile chord and the number of stages in the group are the most important factors influencing the optimum nozzle outlet angle.

The Physikalisch-Technische Bundesanstalt (PTB) will operate an electromagnetic undulator designed for radiometry at the BESSY II storage ring. The undulator has a period length of 180 mm, 21 full periods and a maximum magnetic induction of 0.46 T, resulting in a tuning range of the first harmonic from 5 to 150 eV at 1.7 GeV electron energy. Moreover, the electromagnetic design allows the undulator to be operated in a special mode with the period length doubled to 360 mm, thus accordingly shifting the tuning range to lower energies. The main design parameters of the undulator for radiometric applications, as well as measured magnetic field data, are presented.

The Creation

A large number of articles have been devoted to the problem of calculation of main parameters for single-tier tuyeres. Various methods and equations on the matter have been proposed in the papers. However, they do not provide the necessary information which of these methods allows the obtaining of the main design parameters of single-tier tuyere, which will correspond to the existing standard structures, i.e. will be adapted to modern working conditions of national iron-and-steel enterprises of Ukraine. The creation of above-mentioned methods of calculation is an important question, as it will contribute to the development of more advanced single-tier tuyeres. Five methods have been developed for calculation of the main design parameters of single-tier tuyeres. Appropriate analytical and computational research was conducted using these five methods. It was found that the approximate comparison results of the modern main design parameters of single-tier tuyere on the converters of National iron-and-steel enterprises of Ukraine can be obtained by methods one and four. However, the method four requires some additional graphs which can complicate the development of the calculation program for this method.
