摘　　要：针对松弛型阻尼隔振模型,从动刚度角度分析其与传统隔振模型的区别。通过求解松弛型阻尼隔振模型的传递率,说明系统最优传递率和动刚度的联系。使用波纹管提供刚度及密封,采用小孔阻尼结构形式,设计松弛型阻尼隔振器并对系统的阻尼系数求解。对所设计的松弛型阻尼隔振器进行了动刚度的测试,实验结果和理论预测吻合较好。研究对松弛型阻尼隔振器的优化设计具有很强的指导作用。The dynamic stiffness of a virration isolation model with relaxation type damping is deduced and comparedwith that of a traditional Kelvin vibration isolation model. The relationship between the transmissibility and dynamicstiffness of the relaxation type damping vibration isolation model is discussed. The isolator with relaxation type damping isdesigned by adopting bellow and small hole to generate the damping force. The damping force is obtained analytically forthe small holes. The dynamic stiffness of the designed isolator is measured experimentally. The result is found to be in goodaccordance with the theory.This research is of significant guidance for optimal design of the relaxation type dampingisolators.
