Dynamic Analysis of a One-cylinder Engine Crankshaft

Journal Title: Acta Technica Jaurinensis - Year 2015, Vol 8, Issue 4

Abstract

The article deals with the vibration analysis of a one-cylinder engine crankshaft. For the analysis, a sequential torsional multi-mass vibration model was created of the crank-mechanism. The natural frequencies and natural modes of the crankshaft were determined from this model. The results of the torsional model were verified with a 3D finite element model, which consists of not only the torsional, but every other natural frequency and mode of the crankshaft. From the torsional natural frequencies and the harmonic expansion of the excitation forces, the critical speeds were determined, where resonance phenomena can occur. The relative angular deflection of the two ends of the crankshaft was also determined which characterizes the torsional stiffness of the crankshaft. From the angular velocity function of the clutch, the measure of speed irregularity of the clutch was defined.
