Dasi, S. and Mariappan, B., "Local Non-Linear Analysis of Heavy Commercial Truck Chassis Assembly Using Sub-Modeling Technique," SAE Technical Paper 2013-01-2780, 2013, doi:10.4271/2013-01-2780.
Linear static analysis of heavy commercial truck chassis assembly has become an industry practice during the concept stage evaluation. Non-linear analysis of chassis is rarely performed due to computational time and resource constraints. However, linear assumptions might not be appropriate for certain regions in the chassis assembly. In this paper, sub-modeling technique is applied for solving specific regions in the full chassis assembly to capture the actual boundary information for local non-linear analysis without intervention of user.
