Structural Design and Simulation Analysis of an Intelligent Speed Bump 2021-01-0324

As a traffic deceleration device, speed bumps are widely used to reduce the speed of vehicles and have a good effect. However, in special occasions such as hospital entrance, the bumps caused by ordinary speed bumps are likely to aggravate the pain of patients. In view of this situation, an intelligent speed bump is designed in this paper, which can adjust the height of the speed bump according to the speed of the passing vehicles. When a low-speed vehicle passes by, the elastic link slider module works, so that the upper surface of the speed bump can be elastically lowered to improve the ride comfort of low-speed vehicles. When a high-speed vehicle passes by, the centrifugal locking module will lock the elastic link slider module, and the upper surface of the speed bump will be locked, which plays a role in speed limit. In this paper, SolidWorks and ADAMS/car are used to analyze the process of vehicle passing through the intelligent speed bump. In this process, the maximum vertical acceleration of low-speed vehicles is reduced by 75%, and the vertical speed is reduced by about 70%; The maximum vertical acceleration of high-speed vehicles is reduced by 30% and has a good deceleration effect on high-speed vehicles. This study has a positive effect on the design and application of intelligent road facilities.
