Description

technical field [0001] The invention belongs to the technical field of engine testing, and in particular relates to a dual-purpose dynamometer for a floating motor type engine transient dynamic test and a dual-purpose method thereof. Background technique [0002] The dynamometer is a device used to measure parameters such as the torque and speed of the engine, electric motor, etc. It is an indispensable test equipment in the engine development test. Traditional dynamometers are only used to measure general parameters such as torque and speed, and can only test the parameters of the engine itself, and are generally single-mode (usually transient or steady-state) test dynamometers. With the development of technology and the need to shorten the development cycle, on the one hand, it is necessary to test the transient and steady-state performance of the engine; performance (vehicle speed, acceleration performance, etc.), because the traditional dynamometer cannot accurately sim...

Problems solved by technology

Traditional dynamometers are only used to measure general parameters such as torque and speed, and can only test the parameters of the engine itself, and are generally single-mode (usually transient or steady-state) test dynamometers

With the development of technology and the need to shorten the development cycle, on the one hand, it is necessary to test the transient and steady-state performance of the engine; performance (vehicle speed, acceleration performance, etc.), because the traditional dynamometer cannot accurately simulate the inertia of the vehicle on the bench, the traditional dynamometer cannot meet this requirement, and the dynamic simulation dynamometer cannot be very good engine transient performance test
