Abstract


This research focuses on the testing and verification of decelerations, accelerations and braking space as a function of the degree of loading and the positioning of the load in the load compartment. By conducting a set of tests to assess the impact of load degree and load positioning on vehicle performance in terms of decelerations, accelerations and braking space. Using a specially equipped vehicle, data obtained under various braking and acceleration scenarios will be recorded and analysed. Analysis of the collected data revealed significant relationships between load degree, load positioning and braking system performance. It was found that an excessive degree of loading or inadequate load positioning can significantly affect the vehicle's ability to decelerate efficiently and stop in a suitable space. The impact of weight distribution on vehicle stability during braking and acceleration will also be investigated. Patterns have been identified which demonstrate that incorrect weight distribution can influence the vehicle's stability and its ability to maintain the desired path in such critical situations. In conclusion, the research results highlight the importance of assessing and checking deceleration, acceleration and braking space in relation to the degree of loading and the positioning of the load in the load compartment. These findings can help optimise vehicle design and braking systems for safety and road performance.
