Study On Mechanics Properties Of Cylindricalroller Bearing Based On Frictional Dynamics

With the rapid development of dynamics simulation and finite element simulation technology and a series of science and technology, research and development the development of tribology research is from the traditional experimental research and experiment to the combination of virtual simulation. A series of changes in relative motion between two parts of the surface wear of bearings in the research, and better result in friction and wear of bearing surface, and to explore a series of changes occurred in the contact surface of the bearing friction in the process, to the maximum extent to avoid bearing internal parts between the unnecessary wear.Based on the cylindrical roller bearing as the research object, carries on the analysis of friction dynamics simulation, finite element analysis and temperature field of the. The research contents of this paper include:1.The application of three-dimensional geometric model of 3D modeling software Solid Works to establish a cylindrical roller bearing, the correctness of the assembly and to verify the model, to prepare for the follow-up study.2.The use of dynamic software ADAMS of cylindrical roller bearing model for dynamic simulation, get the roll errotates within a week of retainer of angular velocity curve, rolling body and the inner friction force curve. And the study of bearings in different speed, the change trend of the friction roller and inner3.The use of software ANSYS Workbench static simulation of cylindrical roller bearing model, different position of roller contact stress nephogram, and explain the variation of the image. The friction and the inner ring and roller in ADAMS between the positive pressure into the finite element bearing model, get the dynamics of roller based on the stress distribution in different locations of the contact, and compare the two methods of roller and inner contact stress.4.The establishment of cylindrical roller bearing thermal network model, based on the analysis of 4 methods of thermal network method, the maximum temperature of the key node to calculate bearing micro steady-state distribution when the value of the. Analysis by ANSYS Workbench software for simulation of the heat, the whole bearing temperature field, the static bearing based on the steady-state temperature field distribution and temperature field distribution of bearing based on macro kinetics, temperature field and compare the two methods.
