A cost effective, portable particulate control system was developed, built, and evaluated at the University of Louisiana at Lafayette. Prototype of the presented system was developed for experimental assessment and its computational model was also created for CFD simulation. The experimental and computer simulation results showed that the developed system could efficiently and safely remove and dispose accumulated particulate matter (in the size range of 5 ∼ 1000 μm), and be tolerant to the abrasive properties that the particulate matter may have. The developed particulate control system as well as the applied technology can be further optimized and extended to be applied in aerospace and space engineering to remove suspended particles out from the closed cabinet of aircrafts or spacecrafts. The outcome of this project will also impact other commercial sectors and industries.

This paper validates a simplified finite element model of a light duty truck chassis which was previously developed. The simplified model is used for different computational crash simulations including full frontal impact, offset frontal impact, and oblique impact. The simulation results are compared with those obtained from a detailed chassis model. Through the comparisons, it is found that the present simplified model can be successfully used in the full frontal and offset frontal simulations. However, the current simplified model still needs to be innovated in order to correctly predict the detailed model’s crash behavior during the oblique impact. The present simplified model’s computational stability, reliability, accuracy, and efficiency are verified in this project.
