| Abstract [eng] |
Stopping distance is described as a distance vehicle navigates through from the point when the driver takes an action until the vehicle is fully stopped. The aim of this study is to research how lorry’s mass and its distribution influences stopping distance. Literature regarding factors that might impact stopping distance was thoroughly examined. Afterwards, double axis truck and tugboat with semitrailer was tested for axis load when the cargo mass configuration differentiates. Computer-based simulations and practical trials were applied to assess the length of stopping distance while driving in an urban area and in a rural zone. Obtained results were compared and summarized. The truck was tested with its cargo placed in semitrailer’s front, middle and rear end. The trial showed that the vehicle’s stopping distance was the shortest when the cargo was situated in the middle part of semitrailer, in this particular case to fully stop it would take 3,05 seconds and the stopping distance’s length would reach 18,2 m. The deceleration curve and its reliance to time graph display that with increasing cargo mass the time required for the brakes to fully work also increases. Applying TruckSim software with same parameters revealed that the load on front axis might double while braking in extreme conditions. |
