Abstract

The invention discloses an electric feedback type small engine test bench, which comprises a platform, a processor module, an electric feedback module and a test module, wherein the platform comprisesa working table, a table lifting plate and a chassis frame, an engine under test is fixed on the working table, the table lifting plate is located under the working table and right above the chassisframe, and the chassis frame is located below the platform and matched with the table lifting plate; the electric feedback module comprises a generator and an electric feedback unit, a rotor of the generator is rotatably connected with a rotor of the engine, one end of the electric feedback unit is connected to an output end of the generator, and the other end is connected to a power grid or an energy storage device. The electric feedback type small engine test bench has the substantial effects that the generator is enabled to recycle the mechanical energy in the testing process of the engine,the use of a load is reduced, and a shock absorbing module is utilized to reduce the vibration of the platform through changing the inherent frequency of the platform. Disclosed by the invention is an engine testing method which adopts the generator to serve as a load. The test accuracy is improved according to the method.

Description

technical field [0001] The invention relates to the field of engine testing, in particular to an electric feedback type small engine test bench and a test method. Background technique [0002] The engine online test bench is mainly a kind of equipment for online testing of the basic performance and parameters of the engine. The traditional engine online test bench includes three parts: test bench, operation control box, and load box. Generally, it adopts a split structure, and consumes the mechanical energy generated by the engine through fan blades or electromagnetic brakes as loads. When debugging different models It is necessary to replace the brake loads of different sizes, which not only wastes the mechanical energy, but also takes time and effort to replace the brake load, which seriously affects the test efficiency of the transmitter.
