Dynamic Modeling of a Multi-Axial Simulation Table

A Multi-Axial Simulation Table (rig) has been installed to perform a durability test of the vehicle exhaust system under simulated excitation. As part of this ongoing project, a computational model of the rig was developed using a dynamic simulation package, ADAMS®. The process of model development is described and the results of a correlation study are presented in this paper. Critical features in the model development included a mainframe, main frame supporting arms, the engine and transmission assembly, and the transmission output shaft assembly. Additionally, to accurately perform the model analysis and correlation study, several in-house codes are developed for numerical analysis.
