Problems of support and elastics strains of a measured object

The author presents the results of research aimed at determining the best conditions of supporting large and elastic machine elements such as crankshafts. A number of simulation tests were performed with variable shaft support conditions changed using the author’s system of elastic support of crankshafts. The selection criteria were established for support parameters. Meeting these criteria guarantees that shaft elastic deflections and strains are eliminated. Consequently, such strains will not affect the estimation of geometrical deviations of the measured object.
