转子-弹性阻尼支承结构及转子实验装置

本发明公开了一种转子‑弹性阻尼支承结构及转子实验装置。该转子‑弹性阻尼支承结构包括转子、第一轴承、第一支承件和第一支承座，第一支承座包括衬套和挡板，衬套、挡板和第一轴承限定出第一容纳腔，用于容纳第一支承件，使第一支承件得到稳定且持续的润滑；第一支承件与衬套形成第一油膜腔，与第一轴承形成第二油膜腔，通过分段式的挤压油膜、第一支承件的弹性变形及复杂的流固耦合作用获得较好的阻尼效果；第一支承件设有定位槽，衬套设有定位销，第一支承件与衬套的装配不仅限制第一支承件的转动还保证了第一支承座内的检测通道能够连通第一油膜腔，以测量第一油膜腔的动态压力，为发动机结构动力学设计和振动控制提供数据支撑。

The invention discloses a rotor-elastic damping supporting structure and a rotor experiment device. The rotor-elastic damping supporting structure comprises a rotor, a first bearing, a first supporting piece and a first supporting seat, the first supporting seat comprises a lining and a baffle, and the lining, the baffle and the first bearing define a first containing cavity used for containing the first supporting piece so that the first supporting piece can be stably and continuously lubricated; a first oil film cavity is formed by the first supporting piece and the lining, a second oil film cavity is formed by the first supporting piece and the first bearing, and a good damping effect is obtained through sectional type extrusion oil films, elastic deformation of the first supporting piece and a complex fluid-solid coupling effect. The first supporting piece is provided with a positioning groove, the lining is provided with a positioning pin, and assembly of the first supporting piece and the lining limits rotation of the first supporting piece and ensures that the detection channel in the first supporting seat can be communicated with the first oil film cavity so as to measure dynamic pressure of the first oil film cavity, and data support is provided for structural dynamics design and vibration control of an engine.
