Resilient mounts are essential for anti-vibration and shock absorption applications, making accurate predictions of their static and dynamic behaviors critical for effective design and mechanical performance. This study investigates static and dynamic characteristics of resilient mounts to predict their effects. Tension, compression, and shear tests were performed under quasi-static loading conditions to obtain stress-strain cycle curves. This study includes a review of the Yeoh hyperelastic model, which consists of three parameters, and discusses the calibration of these parameters to describe the hyperelastic material behavior. The parameters were validated through numerical analysis by comparing them with experimental results from quasi-static tests on the resilient mount. The dynamic behavior was further analyzed using modal analysis and frequency response simulations under various preload conditions. Results show that increasing preload significantly shifts the transmissibility curves and resonance peaks to lower frequencies. This study offers valuable insights into static and dynamic characteristics of resilient mounts, contributing to the design and optimization of vibration isolation systems for naval applications.
弹性支座对于抗振动和减震应用至关重要，准确预测其静态和动态行为对于有效的设计和机械性能至关重要。本研究调查弹性支座的静态和动态特性以预测其效果。在准静态加载条件下进行拉伸、压缩和剪切试验以获得应力-应变循环曲线。本研究包括对由三个参数组成的Yeoh超弹性模型的综述，并讨论这些参数的校准以描述超弹性材料行为。通过数值分析将这些参数与弹性支座准静态试验的实验结果进行比较来验证这些参数。在各种预载条件下使用模态分析和频率响应模拟进一步分析动态行为。结果表明，增加预载会使传递率曲线和共振峰显著移至更低频率。本研究为弹性支座的静态和动态特性提供了有价值的见解，有助于海军应用隔振系统的设计和优化。
