In internal combustion engines, due
to the transmission of torsional vibrations caused by the irregularity of the
combustion process to the gearbox, resonance occurs especially at low engine
speeds. Resonance causes noise in the power transmission system. Therefore,
driving comfort reduces and additional loads on the gearbox arise. Nowadays,
with the concern of fuel consumption, the manufacturers turn to engine designs
that keep the engine's working range as wide as possible. In this study, the
mathematical models of power transmission systems using single-mass and
dual-mass flywheel were analyzed and both systems were compared in terms of
engine speed at which resonance occurs. In addition, the effects of the design
parameters such as the mass moment of inertia and spring stiffness on the
resonance behavior of the power transmission system using dual mass flywheel
were examined. It has been observed that the dual mass flywheel drops the speed
which resonance occurs in the power transmission system far below engine idle
speed so that the resonance speed is kept away from the engine's working range.
