Semi-actively controlled suspension systems were devised to reduce the vibrations of railroad passenger cars. Two vertical and one lateral pneumatic servo cylinders were mounted parallel to the air springs on each truck. The acceleration signal of the car body above each cylinder was transfered independently to each controller, and the vertical and lateral controllers were adjusted to approximate the results of the optimum analysis of vertical vibration mode and yawing mode respectively. The system was simply arranged for these reasons. The vibrations of a care body were proved to be reduced by 50 percent in all vibration modes by theoretical analysis and also by a 1/5 scale model car with multi-degrees of freedom. The same reduction was also attained in a full-scale model with a single-degree of freedom. (Wassmann)
