All engines have flywheels or weighted crankshafts that balance out compression and power strokes, maintain idle speed, aid starting and reduce parts wear. Dual mass flywheel is a multi-clutch device which is used to dampen vibration that occurs due to the slight twist in the crankshaft during the power stroke. The torsional frequency is defined as the rate at which the torsional vibration occurs. When the torsional frequency of the crankshaft is equal to the transaxles torsional frequency an effect known as the torsional resonance occurs. When the operating speed of the engine is low, vibration occurs due to the torsional resonance and this can be avoided using dual mass flywheel Spring. This work is carried out to study the effect of arc springs on the dual mass flywheel. The main aim is to increase durability of the arc spring and to elimination of gear rattle. First design steel and brass material springs as per our load. Then modelling in Creo 2.0 A three-dimensional model of a single arc spring are optimized by modal analysis and static structural deformation using ANSYS13.00. In experimentation manufacturing steel and brass springs. Also, to find natural frequency of both the springs with the help of FFT analyser for validation of result
