基于非局部摩擦的鋼絲滾道球軸承接觸仿真與實(shí)驗(yàn)研究
[Abstract]:Steel wire raceway ball bearing is a new type of non-standard rolling bearing, which has the structural characteristics of large radial size and small axial size, which attracts the attention of scientists and engineers all over the world. In recent 10 years, steel wire raceway ball bearings have been widely used in many fields such as construction machinery, medical devices and simulation turntables for aircraft due to their strong anti-overturning ability and flexible structural design. However, the steel raceway is often subjected to cyclic alternating contact loads, which results in contact fatigue and wear, which seriously affects the performance of the shafting. In order to explore the characteristics and rules of contact fatigue and wear of steel wire raceway, it is treated as contact problem in this paper. ANSYS finite element numerical simulation method and contact failure test method are used to study the contact fatigue and wear of steel wire raceway. Based on the non-local friction theory model, the friction effect of a point on the contact surface is not only related to the friction state of the point, but also to the friction state of other points within a certain range of the point. Therefore, this paper firstly considers the non-local friction effect caused by the micro-convex structure on the contact surface, and uses the statistical method to determine the action radius of the non-local friction effect on the surface of the steel wire raceway. The solid models of three-dimensional rough plane and three-dimensional rough cylindrical surface are established. Based on the three-dimensional rough surface, the contact analysis model of steel wire raceway ball bearing is established. The contact behavior between rolling body and steel wire raceway is simulated by finite element method in ANSYS. The three-dimensional rough surface contact model describes the stress-strain distribution, friction stress distribution, shear stress distribution and stress concentration phenomenon more closely to the actual situation, and the simulation results are more realistic and reliable. Under the action of tangential friction stress and cyclic alternating normal contact stress, contact fatigue and wear are easy to occur on the contact surface between roller and steel wire raceway. In the experimental study of contact failure, the contact load can be accurately loaded by changing the thickness of the gasket, and each group of shedding particles under the action of contact load is collected, and the specimens are made together with the steel ball and steel wire raceway that finally occur contact failure. The morphology of the damaged tissue was observed under laser confocal microscope and scanning electron microscope. Compared with the finite element contact simulation results, the characteristics and rules of contact fatigue and wear between rolling body and steel wire raceway are summarized. The experimental results show that during the process of contact between the roller and the steel wire raceway, the micro-convex structure on the contact surface first occurs contact, resulting in stress concentration and plastic deformation. The maximum shear stress exists at a certain depth below the surface of the contact zone. Under the action of cyclic alternating stress, the contact fatigue cracks occur here and then expand and merge to both sides or surfaces, finally falling off to form pitting corrosion. At the same time, it aggravates the wear and tear between contact bodies. The research method in this paper provides theoretical support and experimental basis for the wider application of steel wire raceway ball bearings and provides reference for micro-contact problems in other fields such as MEMS micro-electromechanical system ultra-precision machining and so on.
