Double-rotor test bench with multi-excitation simulation

The double-rotor test bench comprises a base (1), a low-pressure rotor system, a high-pressure rotor system, an intermediate bearing (14) and a multi-excitation simulation system, the low-pressure rotor system and the high-pressure rotor system are both connected with the base (1), and the low-pressure rotor system and the high-pressure rotor system are in supporting connection through the intermediate bearing (14). The high-speed motor is used for realizing relative high-speed movement between the low-pressure rotor system and the high-pressure rotor system; the multi-excitation simulation system comprises an airflow exciting force simulation subsystem used for determining the influence of airflow exciting force on the stability of the double-rotor shafting by changing parameters of airflow; the temperature simulation subsystem is used for determining the influence of the temperature on the performance of the dual-rotor system by adjusting the change of the temperature field of the intermediate bearing (14);
