摘要
设计了金属橡胶、钢丝绳和多层钢板三种全金属隔振器,并对其进行动态试验和静态试验研究。结果表明,三种全金属隔振器不仅具有各自的独立特征,而且都具有良好的干摩擦阻尼性能,其刚度和能耗系数都随着振动幅值的变化呈非线性变化。同时对三种金属隔振器进行了寿命研究,研究了传递率与振动次数的关系。通过研究,对三种全金属隔振器在航空发动机外部管路上的应用奠定了基础。
Three types of metal rubber, steel cable and multi--layer steel plate isolators were designed. The static and dynamic experiments were researched. Those conclusions show the three types of full--metal isolators have own characteristics respectively and good performance of dry friction damping. The relation between the stiffness and coefficient of energy dissipation of the three types of full--metal isolators is non--linear. At the same time the lifetime of the isolators was researched too, the conclusion of the relation between transmissibility and vibration times is obtained. This research establishes the basis for three types of full--metal isolators applying in the outer pipeline of aeroengine.
