The Comparison of Two Precessing Methods of Sliding Bearing in Impact Dynamics Analysis of Finite Element Software
In this article, author studied the application of two models of single point damping-spring model and contact model in the process of impact dynamic analysis.Research shows that the load and force could be transmitted smoothly in all these methods.But there still have limitations in two methods, we could not study the impact response of bearing itself and the shaft neck contacted with bearing in the single point damping-spring model, on the other hand, the penetration of contact parts could not be avoided completely in the contact model, sometimes, the numerical calculation even could not be converged if the parameters were not be set properly in this method.Of course, this two methods also have their own advantages, we could select different model according to different circumstances.
