  • Non Linear Dynamic Analysis of Cylindrical Roller

    2017-1-1 · One of the most complicated and unpredictable non linear behavior of the rotor bearing system is chaos. The proposed research mainly focuses on detecting the chaos in the balanced rotor bearing system. Because of very less research work in case of cylindrical roller bearing, the authors have decided to work on cylindrical roller bearing (NJ 305).
