Abstract

The invention discloses a multi-working-condition simulation test rack based on a multi-axis input type double-rotor motor. The multi-working-condition simulation test rack based on the multi-axis input type double-rotor motor comprises an engine, a planetary decelerator, a double-rotor motor, a detection assembly and a load assembly; the engine inputs power to the planetary frame of the planetarydecelerator through a No.3 clutch; the gear ring of the planetary decelerator realizes power transmission with the outer rotor of the double-rotor motor through a No.1 clutch; the sun wheel of the planetary decelerator realizes power transmission with the inner rotor of the double-rotor motor through a No.2 clutch; and the outer rotor outputs power to the load assembly. According to the multi-working-condition simulation test rack based on the multi-axis input type double-rotor motor in the invention, testing of the motor performance change in multiple working modes can be realized; the experimental working condition range of the experimental rack is enlarged; a vibration excitation device supplies radial excitation to the axial extension part of the motor, and is used for simulating theradial bounce of the axial extension part of the motor in the actual working condition of a vehicle; and thus, all kinds of parameters of the performance of the double-rotor motor can be detected moretruly.

Description

technical field [0001] The invention relates to the technical field of motor testing, in particular to a multi-working-condition simulation test bench based on a multi-shaft input type double-rotor motor. Background technique [0002] In recent years, with the rapid development of hybrid electric vehicles, the electromagnetic coupling method using dual-rotor motors has gradually matured. The use of dual-rotor motors has greatly reduced the volume and weight of the coupling system, and the electromagnetic High-efficiency synthesis of electric power and the effect of stepless speed regulation. Therefore, the structure, performance, and reliability of the dual-rotor motor have a crucial impact on the performance of the vehicle. In order to optimize the design of the new dual-rotor motor, it is necessary to build a corresponding experimental bench to test the performance of the motor in all aspects. Various parameters can deepen researchers' understanding of motors and improve ...

Problems solved by technology

[0003] The existing test benches all use a relatively simple structure, and use the motor, electric dynamometer, speed torque sensor and inertia simulation device to directly test the performance of the motor. Under this test method, an experimental device can only get The motor performance of a driving condition, and the data obtained from it are too idealized and do not meet the real road conditions of the car, which has great limitations, which hinders the research and development of the motor.
