The main bearing wear is often affected by multi-source uncertainties, which also challenges the prediction of wear. In this paper, a method and reliability analysis under uncertainties proposed. Firstly, multi-flexible body friction dynamics model established, in mixed lubrication behavior described average Reynolds equation Greenwood-Tripp rough contact theory. Then, based on Latin hypercube sampling, sample data key are obtained substituted into model, thus obtained, distribution...
Existing tribo-dynamic models encounter challenges in accurately characterizing the intense coupling and notable nonlinearity between component deformation oil film pressure lubricated clearance joints. Consequently, a novel general model based on an absolute coordinate framework has been developed this paper. The equations of motion for flexible multibody systems are formulated nodal formulation. Mixed lubrication defined at spatial nodes reference surfaces by employing mixed...
A multi-roller static model for planetary roller screw mechanisms (PRSMs) is proposed using an energy method to obtain contact load sharing and distribution. The relative positions of meshing points within one pitch are considered calculate structural potential by discretization. By combining force balance constraints with the principle minimum energy, optimization problem formulated derive characteristics. validated through finite element simulations existing experimental results,...
This study fabricated textures on the stator surface of a traveling wave ultrasonic motor (USM) using laser and investigated tribological behavior polytetrafluoroethylene (PTFE) composite friction material stator. Initially, effect with different densities was tested. As results suggested, generation large transfer films PTFE prevented by texturing, adhesive wear reduced notably despite insignificant decrease in load capacity efficiency. Next, 100-h test performed to further effects texture....
A novel static model of planetary roller screw mechanisms (PRSMs) is proposed to obtain the load distribution over threads by an energy method. The method consists structural potential and optimization problem. calculated discretization. And problem, whose objective energy, obtained combining principle minimum with forces balance constraints. result finite element established for validation. Compared previous models, has lower complexity higher precision. To further verify reliability...
