针对传统材料制造的动静压轴承刚度较差的问题,提出一种基于Ti-6Al-4V材料制造六槽深浅腔交错分布的动静压轴承.利用ANSYS有限元软件建立六槽深浅腔动静压轴承流固耦合模型,研究轴径间隙、转速以及偏心率对QSn4-3轴承和Ti-6Al-4V轴承刚度的影响规律.结果表明:钛合金材料制成的轴承刚度优于传统锡基合金材料制造的轴承,各工况参数中,轴径间隙对轴承刚度的影响最为显著,其次是偏心率.该研究可为钛合金滑动轴承的数值模拟和设计提供参考.
Numerical Analysis of Stiffness of Ti-6Al-4V Static and Dynamic Bearing with Six-Groove Deep and Shallow Cavity
In view of the poor stiffness of static and dynamic bearings made of traditional materials,a hybrid bearing with six-groove deep and shallow cavities staggered distribution based on Ti-6Al-4V material was proposed.The fluid-structure coupling model of dynamic and static bearing with six-groove deep and shallow cavity was established by using finite element software ANSYS,and the effects of shaft diameter clearance,speed and eccentricity on the stiffness of QSn4-3 bearing and Ti-6Al-4V bearing were studied.The results show that the bearing stiffness of titanium alloy is better than that of traditional tin-based alloy.The influence of working parame-ters on the stiffness is as follows:the shaft diameter clearance is the largest,followed by eccentricity.The research can provide reference for the numerical simulation and design of titanium alloy sliding bearings.
