In this research the use of water hydraulic Stewart platform in mobile machine driving simulator is studied. The motion platform has six water hydraulic cylinders which are controlled by proportional directional valves. In previous studies problems with the movements of actuators have been noticed. This paper presents some improvements of the controllers of the water hydraulic motion platform. Because the realistic trajectory is the only way to test the suitability of water hydraulic platform, first part of this paper considers the simulation model of the mobile machine and the realization of the connection between water hydraulic 6-DOF motion platform and the simulation model. Different types of trajectories are generated according to the simulation model of the mobile machine and tested with the water hydraulic platform. In this paper it is shown that it is possible to use water hydraulic motion platform to realize driving feel for slow mobile machine.
