| Abstract: | C-L methed in nonlinear dynamics theory is applied in solving some key vibration problems existed in Large Scale Gas Turbines. The nonlinear dynamical models were built first, then analyzed by theoretical method, experimental method and numerical method, to show the dynamical behaviours in various failure cases. Techniques of solving irregular operation of large scale gas turbine in a comprehensive way were given out, and successfully applied to a power plant in Tianjin. |
