At present, electromagnetic induction quenching and nitriding are two commonly used surface strengthening approaches applied in improving the strength of steel parts. In this paper, a comparative study was proposed to research effect these technologies fatigue crankshaft. First modified statistical analysis approach limit load obtain distribution load. Then types crankshafts were selected be ob...

In modern engineering, electromagnetic induction quenching is usually adopted in improving the fatigue performance of steel engine parts such as crankshafts. order to provide theoretical basis for design process, correct evaluation strengthening effect this technique necessary. paper, research aim on a given type crankshaft. First magnetic-thermal coupling process was simulated by 3D finite ele...

This paper presents an analysis of the possibility determining geometric deviations large crankshafts engines using both conventional and alternative fuels. Experimental tests were carried out on a test stand adapted to measure seated with their main journals set fixed supports height positioning reference measuring system. A comparative assessment results was made for selected crankshaft inter...

This article deals with the geometrical deviation measurements of crankshafts large marine engines fuelled conventional or alternative fuels, taking into account problem their deformability. Since detectability deviations a crankshaft supported by prisms depends largely on support conditions assumed and parameters method, study was carried out for two cases support. The first case concerned mai...
