Design Analysis of Spring used in Dual Mass Flywheel

Abstract

All engines have flywheels 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. 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 material changing of springs on the dual mass flywheel. The main aim is to increase the vibration absorbing capacity and to increase durability of the spring and to elimination of gear rattle. First design steel, aluminum, copper and brass material springs as per our load. Then modeling in Creo 2.0 A three dimensional model of a single spring are optimized by modal analysis and static structural deformation using ANSYS13.00. Manufacture, Compare with Ansys 13.00 and FFT analyzer, Validation of result.
