Calculation of the shaft, the calculation methodology, means the calculations, taking into account variations of application of load, the differences in the resultsAbstract
Purpose: The comparison of the shaft calculation results, wich where obtained using different methods and toolkits to perform calculations, calculation schemes and ways of load application.
Approach: The impact of different methods of accounting of single force factor (torque transmitted to the shaft) on the results of the calcultaion was analized. Calculations were made using the traditional method of "Machinery Parts", the Shaft Generator of Autodesk Inventor and the Inventor Simulation Suite environment. Differences in the results of the calculations show a considerable influence of the assumptions made in the calculation of these techniques, and the need of careful attention to the development of calculation schemes.
Findings: The obtained in this work results demonstrates significantly reduced values of allowable stresses, especially for preliminary calculations. This approach reduces the effect of stress raisers but leads to increased material consumption. The use of modern modeling techniques can provide more accurate information about the real loads in detailReferences
