NUMERICAL OPTIMIZATION FOR THE BEST RIGIDITY/WEIGHT RATIO IN TRUCK BODY PARTS
RMC produces truck body parts made of a composite that is lighter than steel but less rigid.
Reinforcements have to be added as judiciously as possible to achieve the required rigidity and the lowest possible weight.
Numerical optimization is the ideal method for this kind of problem.
AERODYNAMIC SIMULATION OF TRACTOR-TRAILERS
Cascades Transport and Manac were working together to develop fuel reduction solutions for tractor-trailers. To this end, a “water drop” trailer was developed, with a rounder shape, in order to reduce drag and, by extension, fuel consumption. The wind tunnel tests showed significant improvements in the level of drag, but the Energotest did not demonstrate any difference in terms of fuel consumption.
CFD AND VIBRATION ANALYSIS OF AN EXPANSION TANK
Exo-s is a leader in the development of injection-molded and blow-molded products.
Exo-s develops the Corvette expansion tank for GM Corp. In the design requirements, the level difference between the internal chambers of the tank must not exceed 3mm. Physical tests showed that the level difference did not meet the requirements.
