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.
