Podgorny's Institute of Mechanical Engeneering Problems of the National Academy of Science of Ukraine popup.description2 Variety of methods for calculation of Kauderer-Rosenberg nonlinear normal modes of torsional vibrations in power transmissions that contain nonlinear clutches is developed. A technique for detecting superharmonical resonating vibration modes based on Shaw-Pierre nonlinear normal modes technique is developed. These methods have high precision when compared to numerical modeling. Numerical analysis for objects that represent torsional vibrations in a power transmission section is conducted. Methodology for experimental research of free vibrations in clad shells is developed. Technique for numerical modeling of such shells' vibrations based on Relay-Ritz technique and B-spline decomposition is developed. Comparison between numerical and experimental results demonstrates high precision of the numerical technique.
