摘要
Abstract
Silicone rubber demonstrated significant application potential in aerospace passive vibration isolation due to its high damping performance across broad temperature and frequency ranges.To address the design requirements of specialized dampers for inertial navigation systems(INS),this study systematically characterized the hyperelastic and viscoelastic constitutive behavior of silicone rubber through static compression tests and dynamic mechanical analysis(DMA).A quantitative constitutive model was established to describe the storage modulus and loss factor over a wide frequency domain(10 to 2 000 Hz).Finite element simulations and experimental tests were integrated to validate the static and dynamic stiffness of a custom-shaped rubber-metal composite damper.Results demonstrate that the developed constitutive model effectively captures large-deformation hyperelasticity and frequency-dependent viscoelasticity.The simulation-experiment discrepancies for large deformations remained below 20％,while dynamic stiffness predictions exhibite less than 8％deviation within the operational frequency spectrum,confirming model reliability.This research provides a robust analytical methodology for the precision design and performance evaluation of INS dampers.The proposed"experimental characterization-constitutive modeling-simulation validation"framework offers critical guidance for optimizing vibration isolation structures under complex aerospace operating conditions.关键词
