Computer-Aided Design and Strength Analysis of the Components of Air-Gas Channel of the Radial Turbine

This paper is dedicated to the issues of designing of outriggers for avoidance of vehicle tilting during its stability tests. An analysis of existing types of outriggers was done by authors as well as legislative requirements on them. The reliable and well-timed operation of outriggers largely depends on the height of their positioning on a vehicle. In order to determine this important parameter a special methodic of determining the tipping angle of the vehicle with the use of computer-aided design (CAD) was composed by authors. The article also contains some main principles of strength analysis of the structure a very important part of which became the necessity of determination of coefficient of friction between the outrigger sliders and the supporting surface. This coefficient has a direct impact on the value of transverse forces appearing at the ends of outrigger beams.

Design And Manufacture

A scheme for the computer-aided design and manufacture of a radial turbine rotor is described based on a package developed by the University of Manchester Institute of Science and Technology. Starting with a one-dimensional calculation, the overall dimensions of the rotor are determined for a specified performance. From these data, the detailed dimensions of the blade profile are evaluated. These are then processed as input data for stress calculations and flow analysis in the blade passages. Interaction between the designer and the program at a number of points enables an optimal design to be achieved. As an aid to assessing the design, a rotating pictorial view of the rotor may be presented on the visual display unit The final output may be in the form of working drawings, blade profile dimensions, or tapes to assist in the preparation of patterns for castings, dies for forging, jigs and templates for machining or straight input to N.C. Machines. Illustrations of the accuracy of the flow analysis methods and typical outputs are given.

Aided Design

Traffic sign frame has to be safe, reliable, and withstand the loads to which it can be exposed during exploitation. This type of product strength is determined by the calculations and tests, which are described in the standards. Prior to the production of a prototype, it is useful to perform strength analysis, using analytical or numerical methods. The article presents the analysis of the existing frame lightening and the strength of lightened frames, using computer-aided design and analysis programs. The analysis showed that the model of this type of product can be lightened, but not all frames can withstand the loads.The paper has been prepared on the basis of G. Gedrimas’ Master Thesis.
