摘要： An actuator is installed between a vehicle body and a bogie frame of a railroad vehicle mounted with a bolsterless bogie, for example. Sensors are installed in at least one of the vehicle body, the bogie, and the wheelset. One or more parameters having a correlation with a steady lateral force are computed on the basis of state quantities obtained by using the sensors while traveling, to determine a thrust command value to be output to the actuator, by applying a predetermined transfer function to the computed value. Concurrently with determining the thrust command value, one or more parameters having a correlation with a fluctuating lateral force are computed to determine a thrust command value to be output to the actuator, by applying a predetermined transfer function to the computed value. These two thrust command values are combined to determine the thrust output to the actuator.
It is possible to effectively reduce the maximum lateral force generated while traveling, thus making it possible to increase the maximum traveling speed.摘要翻译： 例如，在车体和安装有无摇架转向架的铁路车辆的转向架之间安装有致动器。 传感器安装在车体，转向架和轮对中的至少一个中。 基于通过在行驶时使用传感器获得的状态量来计算与稳定横向力相关的一个或多个参数，以通过将预定的传递函数应用于计算出的运动来确定要输出到致动器的推力指令值 值。 同时确定推力指令值，通过对计算出的值应用预定的传递函数，计算一个或多个具有与波动的横向力相关的参数，以确定要输出到致动器的推力指令值。 这两个推力指令值被组合以确定到执行机构的推力输出。 可以有效地减少行驶时产生的最大横向力，从而能够提高最大行驶速度。

A truck frame (13) is steered so as to be aligned with the tangential direction of a curved track by controlling only the steering angle of a rear wheelset (1r) so that during travel along a curved track, the steering angle which is the angle in a horizontal plane of the centerline of the rear wheelset (1r) with respect to an imaginary straight line connecting the center of the truck frame (13) and the center of the curved track is larger than the steering angle which is the angle formed between the imaginary straight line and the centerline of the front wheelset (1f). As a result, a steerable truck for a railway car which has excellent ability to travel along a curve and which can be actually realized simply and at a low cost is provided.摘要翻译： 提供了一种轨道车辆的可操纵的卡车（21），其具有优异的沿着弯曲轨迹行进的能力，并且实际上可以简单且低成本地实现。 通过仅控制后轮对（1r）的转向角度使卡车框架（13）被转向以与弯曲轨道的切线方向对准，使得在沿着弯曲轨道的行驶期间，作为角度的转向角 在相对于连接卡车框架（13）的中心和弯曲轨道的中心的假想直线的后轮轴（1r）的中心线的水平面中，大于作为 假想直线和前轮对（1f）的中心线。 结果，提供了一种轨道车的可操纵的卡车，其具有优异的沿着曲线行进的能力，并且可以实际上简单且低成本地实现。
