| description | In recent years, the speed of express train has been raised by the improvement of technology about the vehicle, truck and electric. However, the speedup of railway vehicle caused high frequency vibration, and thus riding comfort is deteriorated by the resonance of the back seat. In this study, a passenger model with multi-body dynamics (MBD) was established a seat design guideline to reduce the vibration including high frequency. First, in order to construct the passenger model, the authors investigated the vibration characteristics of the passenger and the seat by a vibration test. The vibration test was performed under inputting linear sweep wave from 0.2 Hz to 40 Hz in the front-back or the vertical directions, and accelerations of the passenger's head, shoulders, chest, belly, thighs and the seat were measured. Next, a passenger model with 13 masses and 23 degrees of freedom was constructed by using MBD. Afterward, simulation studies were carried out under linear sweep wave, and the authors compared the simulation result with the experimental one. The simulation result shows the good agreement with the experimental one, and therefore the validity of the passenger model is verified. |
