Research suggests that automotive antivibration mounting NVH reduction is a primary function of these components. The goal is to minimize the transmission of unwanted noise, vibration, and harshness from powertrain and road sources to the vehicle cabin, ensuring a comfortable and refined driving experience. Antivibration mounts are specifically designed to isolate noise and vibration at the source .

Engine and powertrain mounts are vital for isolating vibrations and reducing the transmission of NVH from the engine to the vehicle structure . They work through two crucial phenomena: vibration damping and vibration isolation. Damping is associated with the dissipation of mechanical energy, while isolation refers to the elimination of the excitation frequency . The governing factor for this passive isolation is the viscoelasticity of the rubber composite embedded in the mount . The elastic (spring) component is associated with recovery, while the viscous (dashpot) component handles energy dissipation .

Effective automotive antivibration mounting NVH reduction involves sophisticated engineering. Research utilizes advanced simulation tools like Abaqus for finite element analysis and Isight for parametric optimization to identify key design variables such as mount geometry, stiffness, damping properties, and material specifications . A multi-objective optimization function is developed to find an optimal balance between reducing NVH levels and ensuring mount durability and performance . This technical focus is particularly critical for electric vehicles (EVs), where the absence of engine noise makes other NVH sources more prominent, creating a significant opportunity for custom-designed solutions . As global regulations on noise pollution tighten and consumer demand for quieter vehicles increases, the role of antivibration mounts in NVH reduction will become even more central to automotive design .
