IMPACT OF ROAD IRREGULARITIES ON THE AUTOMOBILE, ROAD SAFETY AND ENVIRONMENTAL POLLUTION. DEVELOPMENT OF A MEASURING COMPLEX TO DETERMINE SUCH AN IMPACT
DOI: 10.33868/0365-8392-2022-3-271-8-13
Abstract. It was established that the automobile overcome different types of bumps while driving. Such irregularities can be either accidental (such as potholes, ruts or swells) or artificial, such as traffic braking devices. The academic paper deals an actual issue of the impact of road irregularities on automobile, elements of automobile suspension, road safety and environmental pollution. In the article is about the importance of development a measuring complex (necessary for conducting an experimental study to determine the impact of road irregularities on the parameters of the automobile’s movement), for which a section of the road will be selected, on which road irregularities of various types will be present. The experimental test will be carried out while the automobile is driving over artificial road bumps (they have standardized parameters and shapes compared to random bumps). This will simplify the mathematical calculations that are necessary to determine the expediency of further research. The measuring complex will include: a fuel flow meter, a speed meter and equipment that will measure acceleration on elements of automobile suspension when automobile crossing road bumps. At the same time, the acceleration on the elements of the automobile suspension will be recorded using the Arduino UNO microcontroller and several MPU 6050 accelerometer sensors. The automobile will be across two types of artificial road bumps (recumbent policeman and elevated pedestrian crossing) in the specified range – from 15 km/h to 50 km/h with intervals of 5 km/h. The test will be carried out in two stages. The first stage consists of overcoming artificial road bumps without stopping. The second stage: overcoming artificial road bumps with a complete stop in front of an obstacle.
Keywords: automobile, automobile suspension, road bumps, impact of road bumps on elements of automobile suspension, environmental pollution, creation of a measuring complex for researching the impact of road bumps on road safety.
