Abstract

The invention provides a common frame of a power assembly system, a design method thereof, and a rail vehicle, belonging to the technical field of rail vehicles. The common frame of the powertrain system includes two main girders and two auxiliary girders, characterized in that the main girders and the auxiliary girders are both hollow structures, and the cavities of the main girders and / or the auxiliary girders A damper is provided, and the damper includes a damping box fixedly arranged in the main beam or the auxiliary beam, and damping particles filled in the damping box. The invention provides a design method of a common frame of a power assembly system and a rail vehicle. The public frame of the powertrain system and its design method and the rail vehicle provided by the present invention greatly improve the damping of the frame structure, thereby achieving the purpose of suppressing the vibration of the frame structure itself, reducing structural vibration radiation noise, and reducing vehicle body vibration.

Description

technical field [0001] The invention belongs to the technical field of rail vehicles, and more specifically relates to a common framework of a power assembly system, a design method thereof, and a rail vehicle. Background technique [0002] Compared with electric trains, diesel trains have the advantages of low investment and operating costs, high operating efficiency, and flexible marshalling. Diesel trains usually adopt a power distribution mode, with the powertrain suspended under the car body as its main power source. The internal combustion powertrain (power pack) mainly includes public framework, internal combustion engine, generator, coupling and other components. The torque is output from the driving end of the crankshaft of the internal combustion engine, and the torque is transmitted to the generator through the coupling, and the generator provides traction power and auxiliary power. Device electricity. The internal combustion powertrain integrates the power syst...
