A study on a configuration of the hydraulic tilting actuator and its experimental evaluations

In this paper a configuration of a load evaluation device for the tilting actuator using hydraulic power is presented, which makes it possible to measure the force acting on the tilting actuator. It is possible to measure only current using the conventional electro-mechanical actuator when the bogie is in the tilting process. This makes impossible to measure the force acting on the tilting actuator. In order to overcome this problem a test device using hydraulic cylinder is proposed. The system is consisted of hydraulic cylinder for the tilting actuation, control system to control hydraulic power, sensors to measure the force and the displacement, and monitoring system for the user interface.
