In this paper, an attempt is made to replace the existing spring-damper suspension system of a two-wheeler by the compliant mechanism. Suspension details of Hero Igniter bike were obtained and analysis of spring was made for static and total deflection. The initial topology of compliant mechanism was obtained through topology optimization in ANSYS. Final topology along with the shape and size of members of compliant mechanism were obtained through trial and error method. Modal and harmonic analysis of obtained compliant mechanism was done to get frequency response curve which subsequently used for calculation of equivalent damping coefficient of the compliant mechanism. Using the equation of force transmissibility, the force transmitted at various frequency ratios was calculated with the help of equivalent damping coefficient obtained for the compliant mechanism. These values of force transmission were then compared with the corresponding values of the spring-damper suspension system. The force transmission values of compliant mechanism were found to be less than the spring damper suspension system leading to the conclusion that the existing suspension system can well be replaced with the complaint mechanism.
