- A pioneering methodology for frequency-domain detection and analysis of bifurcations of periodic nonlinear vibrations using large-scale models of structures with joints has been developed. The possibility of bifurcations in realistic whole-engine models of gas-turbine engines has been discovered and analysed for a first time. The results open a new research area in the gas-turbine engine nonlinear dynamics. The method has been implemented by the author in the in code and delivered to Rolls-Royce plc. It is used by the company to analyse the nonlinear contact dynamics problems (Jeffrey.Green@Rolls-Royce.com).
