Recently, the importance of reinforcing the durability of automobile parts to withstand high load inputs has increased. The insulator, located on the top of the strut or shock absorber of the front and rear suspension and attached to the body, transmits loads from the wheel and road surface, insulates vibration and shock, and contributes to ride comfort and handling performance. However, the existing insulator’s inner rubber experienced excessive deformation during durability testing, leading to weakened durability and creep performance. To address this issue, increasing the rubber’s hardness was attempted, but this resulted in inferior NVH (Noise, Vibration, and Harshness) and R&H (Ride and Handling) performance. In this study, the insulator’s structure was redesigned by eliminating the existing inner/outer rubber structure and applying a stopper structure to the upper and lower parts. This design aimed to implement secondary characteristics under large load inputs, according to actual vehicle requirements. The redesigned insulator demonstrated improved durability and characteristics, optimized weight reduction.
