Aerodynamics drag reduction of commercial trucks
This thesis deals with the airflow over a double trailer Gull Wing truck, with a view to reducing the drag of the truck. To investigate the flow over the truck, a 1:20 scale double trailer truck model was designed and constructed from chipboard for wind tunnel experiments. The overall size of the …

A comparative study of modified passenger railway vehicle trucks
There has been renewed interest in rail transportation driven by the need for alternatives to congested highways and environmental concerns. The conventional railway truck designed for operation at high speed of approximately 200 km/hr makes use of stiff primary suspension elements to provide good …

Experimental Evaluation of a Trailing-Arm Suspension for Heavy Trucks
… of a prototype trailing-arm suspension for heavy trucks. The primary goal of this new suspension is to match or improve the kinematics and dynamic performance of an existing "Z-bar" suspension. Significant reductions in cost, weight, and number of parts are the main reasons for this redesign. A …

Effects of baffles on damping lateral fluid sloshing oscillations in tanker trucks
Partially filled heavy-duty tanker trucks maneuvering constant radius turns or lane change maneuvers have lower rollover threshold than other vehicles because of the high center of gravity and dynamic sloshing of the liquid payload. Payloads are often toxic and hence, rollover accidents can be …

Stability analysis of partially filled tanker trucks using a finite element modeling approach
The point of rollover for a tanker truck carrying fluid cargo is of great importance due to the catastrophic nature of accidents involving such vehicles. Payloads are often toxic or flammable, thus, predicting the threshold of rollover effectively is of great value. Furthermore, the liquid load …
