By their nature, combustion engines deliver power in short pulses which create torsional vibrations and noise emissions both within the engine and the driven equipment. Centa Antriebe has addressed their attenuation with the innovative use of simulation software. This article is based on a paper presented at the recent Torsional Vibration Symposium.

Driveline noise and vibration

Rotating equipment is the main source of noise and vibration in a driveline. A flexible coupling is used between the engine and the driven side in order to attenuate critical vibrations and to compensate misalignment under operating conditions. Hence, it is necessary to simulate the driveline in order to identify the critical speeds, loads and the magnitude of the vibratory torque when the shaft system experiences torsional oscillation.

During the combustion of a single cylinder in a multi-cylinder diesel engine, the crankshaft receives a torque pulse which can be modelled as an energy function containing the...
