This study focuses on the analysis of horizontal acceleration and its influence on load stability during transportation. The main objective is to assess how the duration and intensity of acceleration affect the risk of load tipping or overturning, a crucial issue for safety in freight transportation.
II. Theoretical foundations
The theoretical approach relies on modeling the dynamic forces at play. By studying Cartesian coordinates and the center of gravity, the behavior of the load under various forces can be predicted. Calculations integrate inertia force, normal force, and tangential force, with particular interest in the critical tilt angle, determinant for load stability.
III. Experimental setup
The experimental setup involves the use of a specific load model, with precise dimensions and weight. The experiment aims to simulate real transportation conditions, focusing on variations in the center of gravity and the effect of these variations on load stability.
IV. Acceleration test approach
The experiment measures the impact of horizontally applied acceleration consistently. The analysis focuses on the relationship between the load tilt angle and the time elapsed since the application of acceleration, providing valuable insights into the tipping threshold.
V. Comparative analysis of solutions
Comparing analytical and numerical solutions validates the accuracy of theoretical models. Emphasis is placed on the consistency of results regarding the tilt angle, a key factor in preventing load overturning.
VI. Impact of test duration
The study explores how the duration of acceleration application affects the tilt angle. This analysis helps understand critical thresholds for varying exposure durations to acceleration, providing essential data for designing safety protocols in load transportation.
The findings of this research offer important insights for enhancing safety in load transportation. The discoveries pave the way for future research, particularly on the effects of non-constant acceleration and their practical implications for the design of handling and transportation protocols.
