Analysis of Helicopter Engine Crankshaft Torsional Vibration Based on ADAMS

Abstract:

To address the problem of helicopter engine crankshaft fracture in engineer, this paper carried out an analysis of an inline four-cylinder engine torsional vibration, applying virtual prototyping technology based on ADAMS. According to this analysis, draw several orders of crankshaft torsional vibration natural frequency and the main vibration modes. This paper carried out a harmonic analysis of the disturbing torque acting on the crankshaft and torsional vibration amplitude of the free end relative to the flywheel, and obtained Critical speed map of crankshaft torsional vibration. These results can offer theoretical basis for engine optimization design.
