INVESTIGATION OF THE GENERAL STRESS DISTRIBUTION IN IMPELLER WHEELS

摘要

The experimental Investigations with regard to the strength of im¬peller wheels are intended to provide a logical supplement to calculations and to compare theoretical results with stress concentrations presently covered by the theory. While the preparatory work proceeded, which covered the conversion of the test stand for the investigation of stresses in Im¬peller wheels as well as cementing tests for the manufacture of models and preliminary tests with regard to the application of different measuring methods, the data and program of calculation for the electronic computer were prepared. The period allowed under the present contract, which is covered by this report, was too short to enable' a sufficient number of re¬producible experimental Investigations to be conducted which would permit a detailed comparison to be made with the calculations.
