Abstract

The invention discloses an electromagnetic compatibility loading test system compatible with a motor and an electric assembly. The system comprises a test bench body, a darkroom, a first shielding soundproof chamber, a second shielding soundproof chamber and a shielding control chamber. The test bench body comprises two sets of dynamometers, a movable mounting base, a dynamometer upper base and adynamometer lower base; the power of one dynamometer is transmitted to a tested piece through a through-wall shielding shaft, a bearing base and a ball cage coupler; the power of the other set of dynamometer is transmitted to the tested piece through the through-wall shielding shaft, the bearing base, a cross coupler and the ball cage coupler. The compatible electromagnetic compatibility loading test of the motor and the electric assembly is realized, the loading test of the electric assembly under the real vehicle working condition can be simulated, the influence of signal transmission on thedarkroom is reduced, the shielding performance required by the standard is satisfied, the vibration during the test is reduced and the darkroom with different widths is adapted.

Description

technical field [0001] The invention relates to an electromagnetic compatibility loading test system for a motor and an electric assembly, in particular to an electromagnetic compatibility loading test system for a compatible electric motor and an electric assembly. Background technique [0002] In the electromagnetic compatibility loading test, the loading test of the motor requires a higher speed and a smaller torque, such as the speed is not lower than 12000rpm, and the torque is not The torque is lower than 3000rpm and the torque is above 1000Nm, that is, the loading system on both sides is compatible with the above conditions; when testing the powertrain, it is hoped that the installation position of the powertrain is the same as or close to that of the actual vehicle. The traditional electromagnetic compatibility loading test bench is not compatible with the appealing conditions, so a double-output gearbox is added in the dark room, one output realizes high-speed low-t...
