AI Technical Summary

Problems solved by technology

[0003] At present, the high-speed hydrodynamic experimental towing technology uses the rotation of the motor to provide power, and the maximum speed can reach 25m / s, but there are still shortcomings: (1) At present, the trailer is generally driven by a motor, and the motor connecting bearing is prone to wear during use , has an important influence on the test towing speed simulation, and needs regular maintenance and replacement, which affects the progress of the test; (2) At present, the towing system requires real-time control by personnel in the vehicle. In the middle, the acceleration should not be too high, which severely limits the maximum simulation speed of the trailer, and under high-speed conditions, it has certain safety hazards for the experimenters
