Influence of Tipping Angles and Body Shapes on Payload Discharge Efficiency in Dump Trucks

The payload retention and material outflow pattern during the unloading process of dump trucks are critical factors influencing the efficiency and effectiveness of operations in construction and mining industries. This paper investigates the impact of tipping angles and the shape of the dump truck body on payload retention and outflow characteristics. Using FEA methodology, we explore the material outflow pattern for different body geometries such as box body, scoop body etc. for comparative analysis in order to optimize the shape for better & effective unloading. The results demonstrate a comparative estimation for an optimal body shape configuration to effectively unload payload and correlation of payload retention at various tipping angles.

The current study also describes the effect of high cohesive forces between the payload particles on the discharge efficiency, and the pattern of mass flow rate is mapped against the tipping angle for various types of material properties for comparison. The paper also highlights the outflow pattern for various material types due to gravity when the body is kept at a particular tipping angle.
