Abstract:

Abstract: In order to analyze the multiple dynamic responses for model validation of multiple dynamic systems, this paper proposed the analysis method based on the enhanced error assessment of response time histories (EEARTH) and the analytic hierarchy process (AHP). The EEARTH method was used to calculate the characteristic errors of the multivariate dynamic time series. The errors had to be translated into scores between 0 and 100% because they had different value ranges. The AHP method was performed to determine the weights of the three EEARTH scores and the weight of each response on the overall AHPEEARTH score according to the knowledge of experts. Moreover, the AHPEEARTH score of a multiple dynamic system was computed. Furthermore, a driver side occupant restraint system mathematical dynamic model (MADYMO) model was used to demonstrate the validity of the proposed method for model validation of multivariate dynamic systems.
