加载平台连杆式联轴器设计与分析
|
摘要
针对某一风力发电机组六自由度加载实验平台的需求,设计了一种连杆式联轴器。该联轴器一端与加载平台嵌接,在补偿加载平台所产生的各向角度及位置偏差的同时并能稳定的传递扭矩。考虑到普通膜片式联轴器的各向偏差补偿能力小,角度补偿过程中会产生额外的轴承负荷等问题,该联轴器采用连杆代替原有的膜片结构;连杆两端采用关节轴承连接,在提升各向偏差补偿能力的同时而不产生轴承负荷。基于空间几何知识建立了该联轴器连杆的分布与长度关系的数学模型。为了进一步对此联轴器进行研究,先利用ANSYS workbench对联轴器静载转矩工况进行了应力分析。得出主要部件的应力应变分布云图,并进行强度校核。
According to the requirements of a six degree of freedom load test platform for a wind turbine, a kind of connecting rod coupling is designed. One end of the coupling is embedded onto a loading platform which can compensate for the angle and position deviation and transfer torque at the same time. Considering that the compensation ability of the diaphragm coupling is small and the additional bearing load will be produced in the process of angle compensation, the coupling adopts the connecting rod to replace the original diaphragm structure. Both ends of the connecting rod are connected by a joint bearing which can improve the ability to compensate for deflection and no bearing load. A mathematical model of relationship between the distribution and length of the coupling rod is established based on spatial geometry knowledge. In order to further study the coupling, in this paper, the stress analysis is carried out by using the ANSYS workbench static load torque. The stress and strain distribution nephogram of the main components is obtained and the strength check is carried out. It provides some guiding significance and reference value for the design and research of the connecting rod coupling on the loading platform.
