MODELS AND ALGORITHMS FOR THE CRANKSHAFT DESIGN

Abstract

In the paper a programming system is presented which gives the possibility to do the calculi for the checking and designing of the combustion engine crankshafts. Complex models are used which enable the study of the dynamic stresses, longitudinal and torsional vibrations by using the hypothesis of the deformed and unfixed bearings. The elasticity of the crankshafts is taken into account when calculating the strength in the bearing, enabling the removement of the undetermined that appeared The method of the finite element is used to establish the concentration of the stresses used for the safety calculus. The programming system is accessible, it offers efficient pieces of information in designing of crankshafts and it is able to give best solutions in a certain context.
