摘要

Anti-Vibration Mounts (AVMs) are critical components for vibration mitigation, optimizing performance, and enhancing the longevity of vibratory systems. Choosing the right AVM is crucial for maintaining system reliability in all operating conditions. This study proposes and validates a robust, cost-efficient Finite Element Analysis (FEA) methodology for accurately estimating the nonlinear static stiffness and the system-level dynamic response (quasi-static dynamic stiffness) of AVMs. The methodology provides a structured approach for evaluating AVM performance during earlystage compressor design, particularly in scenarios where comprehensive supplier performance data is unavailable. Employing a non-linear FEA approach enables efficient selection of suitable Anti-Vibration Mounts (AVMs) without resorting to costly, time-consuming experimental testing. By incorporating a nonlinear hyperelastic material formulation, a more accurate FEA model is developed in commercial software to simulate AVM behavior under various loading conditions. Because the model uses purely hyperelastic material laws, it captures only time-independent stiffness characteristics. Consequently, the predicted dynamic response corresponds to the quasi-static dynamic stiffness, which is useful for preliminary design evaluation but does not account for the material’s intrinsic viscoelastic, frequency-dependent stiffening behavior. Thus, the methodology provides valuable guidance for AVM selection in low-frequency vibration isolation applications, establishing estimated operational limits based on quasi-static stiffness. It is found that during system resonance, the effective quasi-static stiffness decreased, with the AVM having Neoprene rubber showing a minimum value of 974.91 N/mm, AVM having natural rubber exhibiting a minimum value of 845.0197 N/mm and the AVM consisting of silicone rubber showing the lowest stiffness of 99.2685 N/mm. The FEA results aid in understanding vibration control in compressor systems and offer valuable insights for engineers involved in designing and optimizing vibrating systems. Testing conducted with an accelerometer and FFT analyzer reveals that the compressor’s frame structure incorporating Neoprene AVM has a vibration response of 75 dB at a frequency of 25 Hz. It is found that the deformation in neoprene rubber AVM is less as compared to natural rubber AVM and silicon rubber AVM.
