Comparative CAE Study for Driveline Elements & CNG Cylinder Mounting Arrangements with Pro/Mechanica & Nastran

Abstract

Sevral software are available for Computer Aided Engineering. Nastran is one of the popular software in the era of CAE, because of the accuracy of the results with the actual one, but because of the timetaken for the analysis, cost of the software, also skills required for software handling, it is popular amongst the big scale industry only. Pro/Engineer is one of the most used software in industry for modeling purpose. Pro/Mechanica is a module from PTC (Parametric Technology Corporation) for the CAE with Structural & Thermal analysis. Mechanica uses P element, where as Nastran uses H element theory. So, to check both these theories, some components are selected for the analysis, in which same loading & constraint conditions are maintained. After carrying out this exercise, it can be concluded that, almost in all the models Mechanica results falls with in +-7 % of the Nastran results. So, when modeling is in Pro/Engineer, and wants to analyze any part quickly, it is highly recommended to go for the Pro/Mechanica, so that design lead time can be reduced, to some extent.
