Abstract: The Project involves nonlinear implicit analysis of the Roll over protective structure of a tractor using 1D Elements like BEAM, BAR, SPOTWELD instead of conventional 2D Shell elemental model. Normally, the CAD model is represented using 2D Elements in FEM, Due to that the pre-processing time and final computation is very high, 1D Element representation will be faster to build and simulation can be done lot quicker. The objective to run complicated nonlinear implicit analysis on vehicle structure using both 1D Model & traditional 2D model thereby capturing displacement, stress, strain, reaction force load-displacement plots, and energy-time plots and correlate the results. If the result correlation is good, then this new way of FE Modeling will help in reducing the lead time of these kind of analysis.
The energy - time plots collected give us an idea about the amount of energy the structure could absorb during the roll over. Similarly the force displacement plots can give information about the load carrying capacity of the cab structure. The correlation between the simulation results of the 1D & 2D finite elemental model was compared, the results showed very good correlation between these 2 models.
Keywords: Roll Over Protective Structure, Nonlinear Implicit Analysis, Hypermesh, and Abaqus.
