左右振動加速度の実測値に基づく転覆限界風速評価に関する一考察

抄録

The critical wind speed of overturning obtained by the RTRI detailed equation, which is used in the static analysis of railway vehicle overturning under cross wind, tends to be lower than that intuitively estimated because it assumes the superposition of the worst conditions. In order to improve the accuracy of the evaluation, the previous research focused on the aerodynamic coefficients that have the greatest influence on the calculation results, but few studies on the lateral vibrational inertia force have been conducted. Therefore, in order to evaluate the critical wind speed of overturning reflecting the actual conditions, we examined an evaluation method based on the measured value of the lateral vibrational acceleration.
