In order to research the principle of crankshaft horizontal-bending vibration, free modal experiments of 4105 diesel engine crankshaft vibration was designed and done. Vibration parameters of free vibration, torsional vibration, vertical-bending vibration and horizontal-bending vibration were obtained respectively through different measurements points setting and motivation techniques. Through analysis of frequencies and models, a conclusion was drawn:the torsional vibration was just coupling with the horizontal-bending vibration.

Engines have been designed to avoid low-harmonic-order resonant torsional vibration in a commonly-used engine speed range, but the authors have found that, in some engines, especially turbo-charged engines, a significant degree of a low-harmonic-order exciting torque acts on the crankshaft. In these engines, the amplitude of non-resonant low-harmonic-order torsional vibration is almost as large as that of the resonant one and the amplitude of non-resonant vibration can not be controlled by a damper. Accordingly, to investigate the characteristics of non-resonant low-harmonic-order torsional vibration is important. This paper describes the characteristics of non-resonant and resonant torsional vibration for a vee-type six-cylinder diesel engine.
