Flexible suspension system like bogie mechanism type suspension is used for running equipment of crawler-type construction machine especially to improve the comfortability in riding. However, in the running equipment with bogie mechanism, there are many unclear points in the dynamic behavior and loads due to the complicacy. This paper shows the dynamic behavior of crawler-type construction machine with a bogie mechanism when it travels over a bump by using a simulation method. The fundamental method has been established in the first report of this study. The time histories of the acceleration at the operating seat position and the suspension forces are calculated. The simulation results are compared with experimental results and the validity of the simulation method is verified.
