    Abstract

    The lack of sufficient evaluation criteria for motion systems has contributed to perceivable differences in motion cues among similar airplane simulators. To resolve this issue, criteria for simulator motion cueing and evaluation must be developed to insure uniform and optimum cues within a motion system's workspace. Therefore, an improved evaluation method is proposed to enable a better assessment of motion cueing within the workspace. To demonstrate the effectiveness of the improvement, an off-line simulation of a motion system is developed and used for the evaluation. A common motion cueing algorithm is incorporated in the simulation to control a motion platform model. Test signals that approximate typical airplane specific forces, for selected maneuvers, are used to drive the simulation. During each simulation test run, a platform trajectory is recorded for the maneuver. The trajectory data are then processed by an optimization routine that determines the dynamic workspace limits as a function of the trajectory. The time histories of the trajectory and the workspace limits are then plotted for evaluation. Presenting the platform trajectory along with the dynamic workspace limits provides another way of evaluating the quality of motion cues within the workspace. Augmenting the existing motion criteria that are used in current evaluation methods with criteria based on the dynamic workspace limits yields an improved evaluation method. This improved evaluation method contributes to the development of criteria for motion evaluation.
