Abstract: With the rapid development of new energy automobile industry at home in recent years, the penetration rate of new energy vehicles in China has exceeded 27 % in 2022. Various automobile related enterprises have a lot of development, innovation and application of new technology products, and the test technology for product development has also been a lot of innovation and development. The dual motor drive reducer static torsion test bench proposed in this paper is an important performance verification solution for the new energy dual motor drive gearbox development stage. Based on the parameters of new energy dual motor drive gearbox and the principle of static torsion test, this paper puts forward the overall design scheme of static torsion test bench. Under the total design scheme, the drive unit, data acquisition system and control unit are designed. Therefore, this paper is of great significance for the development and design of the static torsion test bench of the gearbox driven by the new energy dual motor, and provides a method reference for the development and design of the bench test solution.
