Abstract: The measurement of the axial stiffnesses of the cranks of four full scale crankshafts, supported by the engine main bearings, is described. The results are discussed and compared with those of the calculations using six published formulae. The relationship between the coefficients and the angles of adjacent cranks, or the “mean” crank angle, is investigated. The experimental results are verified with the theoretically determined shear force moments for axially loaded adjacent cranks. The experimentally and theoretically determined stiffnesses are compared and finally proposals are made for future work.
