The present suspension system’s major problem was the reduced life span due to the higher natural frequency subjected to resonance factor and the higher Vibration amplitude in the range of 8.78 Hz. The total deformation was subjected to the 0.55mm; hence the life span of the suspension is constantly decreased; it was observed that every one year, the suspension was to be replaced frequently, this may cause higher economy and less comfort while riding with the existing suspension system. Hence, this analysis aims to reduce the frequency levels and deformation by introducing the natural rubber to reduce the Vibration improved life, An enhanced suspension system with natural rubber was developed in Pro-E model, and it was imported in Ansysto evaluate the first six modes of the suspension system. The analysis is compared without a rubber and with rubber. From the experimental results, it was observed that the research with Natural rubber posses very low Frequencies 0HZ,0.128HZ,0.129HZ,0.195HZ,0.201HZ,0.737 HZ for 1st,2nd,3rd,4th,5th and 6th Modes respectively; the experimental results prove that from the two cases without a rubber and with rubber the results obtained with rubber is strongly recommended because of very low frequencies; hence it is strongly recommended that New Enhanced system with rubber can be used by replacing existing suspension in the market to reduce noise, Vibration as well as Human safety. The load of 3232 N was applied to find the Harmonic response of the system in both cases with rubber and without rubber. In the case of rubber [enhanced suspension system]. The amplitude of vibration was gradually decreased while compared without rubber with the increase in frequencies of the system, and the amplitude at the sixth mode is very low, 10.929×10-001 mm. Hence enhanced suspension can be used better insafety, vibration and noise than the existing Suspension system.
