Design of the Downhill Automatic Liquid Damping Reduction Mechanism on the carbon-free car

Abstract

The carbon-free car is driven by gravity potential energy, through the mechanism to complete the specific direction control and avoid obstacles, to achieve the driving purpose of the car. The event is a national science and technology innovation activity project organized by relevant departments. It is a competition that demonstrates the engineering training and comprehensive ability of college students. Based on the “S” and “8” glyphs around the pile competition, a new circular track was added, and the track was randomly set with intermittent barrier walls and up and down ramps. Small cars that do not have the ability to climb and do not have speed control on the upper and lower ramps make it difficult to complete the race. To this end, for the content of the new project, the automatic speed reduction mechanism for the carbon-free car downhill is developed. Under the condition that the gravitational potential energy of the carbon-free car on the downhill is constant, the stall phenomenon at the time of downhill is effectively solved, the safe driving speed is adjusted, avoid the problem of out of control when escaping the intermittent barrier wall on the circular track.
