(3) Torsional Vibration. Torsional vibration occurs when the crankshaft twists because of the power stroke thrusts. It is particularly noticeable on engines with long crankshafts, such as in-line engines. It is a major reason why in-line, eight-cylinder engines are no longer produced. The vibration is caused by the cylinders furthest from the ...

For the torsional vibration case, the differential equation governing this non-linear single degree-of-freedom system can write as [6, 7]: (6.1) where is the non-linear damping function and is the non-linear spring function. Eq.(6.1) is similar with the Voigt model linear equation: where c is the damper viscosity and k is the spring stiffness.
