Finite Element Structural Analysis as Applied to an Automotive Door Structure 740320

Structural problems encountered in engineering design tend to be inherently complex in nature. Establishing the structural idealization which approximates the true structure constitutes a prime problem. Finite Element Structural Analysis leads to better results than current classical practices because it permits a more accurate representation of the true structure.The objective of this study was to determine if finite element structural analysis can provide meaningful structural design predictions within the allotted design cycle and provide better designs at reduced costs. Application was made to a door structure. Various techniques were developed covering analytical modeling of complex structures and automated input data generation and output data interpretation using the graphic system.The results of the study show finite element structural analysis, when used with an interactive graphic system, can be used successfully as a powerful design tool for automobile body components.
