摘要
为了满足高温、低温、腐蚀环境特殊工况下阻尼减振的需要,对以干摩擦阻尼进行减振的阻尼器的开发一直是工程技术人员的一个主要研究方向。多层环形钢板阻尼器是借助于载荷作用下多层金属环之间的干摩擦力耗散能量,实现阻尼隔振的一种新型阻尼器。为此,从弹性力学的角度建立静力学模型,对多层环形钢板阻尼器的弹性元件进行静力学研究。通过选取应力函数对力学模型进行求解,得出此种类型阻尼隔振元件承受载荷时的力学特性,为设计及应用该种类型阻尼器提供理论依据。
To satisfy the need of vibration reduction under extreme temperature or erosive environment,the engineers and the manufacturers have done a lot of study on dry friction damping. Multilayer steel plates damper is a new kind damper. When the damper deforms under the load,it can dissipate the system energy through the dry friction force among the layers. A static model was built in this paper based on elastic mechanics. The research on the damper’s elastic element has been done based on the elastic theory. The model of the mechanics was solved by choosing the stress function,then,we got the mechanics characteristic of the damper under the load. All the results are very useful to design and application of the damper.
