Abstract

Pretest analysis is a crucial step of the process for experimental modal analysis, directly affect the test accuracy. A general procedure for pretest analysis of a vehicle body frame has been presented using CAE approach with software Virtual Lab. After the modal parameters are acquired from FEM analysis, the CAE based MAC method is used to optimize the measurement location and direction. The selection of an appropriate set of measurement locations and directions including initial accelerometers placement and test excitation point location are defined based on MAC method by Virtual Lab correlation part. Finally, for purpose of validation, the FEM modal analysis is compared with operational modal analysis. The results comparison showing that the present pretest analysis approach is more accuracy and efficiency.
