Transmission Line Co-Simulation of Rolling Bearing Applications

Abstract

Connectivity, i.e., connecting different types of simulation tools, becomes increasingly important. The objective is to be able to do cost effective simulations of a large system by utilizing existing tools together. The TLM (Transmission Line Modelling) co-simulation technique is stable, does not have numerical problems, and is proven. It has potential for being a cosimulation technique of general usage. The aim of the paper is an evaluation of TLM technique for rolling bearing applications via a study of a grinding spindle model. The conclusion is that the results of TLM and non-TLM simulations are similar for a realistic application with rolling bearings and applicable for engineering purposes. The numerical stability and performance are satisfactory for the considered application.
