For effective track maintenance, it is essential to clarify the relationship between vehicle running characteristics and track irregularities. Therefore, in this study, we predicted vehicle wheel loads due to track irregularities using the vehicle dynamics simulation, and clarified this relationship. Additionally, we have developed more usable prediction method that combined the statistical prediction model and the vehicle dynamics simulation. As a results, we can predict vehicle dynamic reactions due to track irregularities easily and accurately.
