Petrenko O. Scientific - technical principles of valuation of noise and vibration in vehicles

The thesis deals with the scientific - technical framework regulation of noise and vibration of vehicles examined working conditions of drivers of cars, nature of work in order to develop recommendations to improve the hygienic conditions, reduce noise and vibration in the driver's seat and, consequently , reducing the likelihood occurrence of an accident. It is established that the criteria for hazardous work environment include: noise, overall vibration severity and intensity of labor. It is shown that the obtained results indicate a relationship between working conditions and road safety . The necessity of improving regulations that determine the maximum permissible levels of noise and vibration in the workplace drivers of vehicles. In this paper, the mathematical model of the driver to ensure safe traffic conditions in a situation in which there is a rapid change in the parameters of the vehicle and on the basis of experimental studies defined thresholds depending on reaction time of drivers from the sound pressure level of noise and the time of its action. Particular attention is paid to the results of experimental studies that defined thresholds of acceptable performance noise and vibration in the workplace driver. To achieve these goals, the program algorithm and experimental studies to assess sensorimotor reactions of drivers under the influence of unfavorable factors. The author improved mathematical model of road safety under the influence of unfavorable factors , as well as the results of theoretical and experimental researches formulated a number of recommendations to amend the existing rules and regulations on road safety and the draft regulations on road safety.
