Turboshaft engine complete machine dynamics double-rotor test bench

The invention discloses a turboshaft engine complete machine dynamics double-rotor test bed, relates to the technical field of aero-engine tests and tests, and solves the problem that a double-rotor test bed in the prior art cannot simulate the real working environment of an engine due to too low rotating speed. The system comprises a driving system, a rotor test piece, a vacuum explosion-proof system, a lubrication cooling system and a monitoring and control system, the driving system comprises two driving units, wherein one of the driving units is a movable unit, the movable driving unit is connected with the rotor test piece through a central transmission bevel gear shaft; meanwhile, the turbine air inlet casing is provided with two supports used for fixing the central transmission bevel gear shaft. In the invention, vacuum environment is created for the rotor with the blades; wherein the central transmission bevel gear shaft and the rotor test piece can be arranged in a non-vertical manner; and two drivin
