A new human factors research laboratory has been developed to provide reliable human-performance data for the design of improved off-road vehicle operator workstations. The principal research tool within this laboratory is a vehicle operations simulator. The simulator consists of a hydraulically driven platform upon which a vehicle operator's enclosure or workstation can be mounted. Under computer control, the simulator is capable of motion with six degrees-of-freedom. With this capability, the simulator's motion can be programmed to reproduce operator workstation vibration experienced in operational field environments. Both field recorded data and mathematical simulations of existing and proposed vehicles can be used to command the simulator motion. In addition to simulating vehicle motion, the simulator is capable of producing realistic control and monitoring tasks for the operator, as well as operator enclosure environmental conditions. This paper describes the research objectives for which the simulator was built, the specifications used in the design of the vehicle motion simulator system, the hardware selected in implementing that design, and the computer control used to simulate both field and artificial “ride” histories.

A stewart platform type motion simulator[1] has been developed, in order to generate the HMMWV (High Mobility Multipurpose Wheeled Vehicle) motion. The purpose of this simulator is to test the stabilization system of the mobile surveillance robot that is mounted on the HMMWV. For developing this motion simulator, the multibody dynamics model of the motion simulator has been created using the general purpose dynamic analysis program ADAMS to validate the design of the motion simulator. Dynamics and control co-simulation model for the motion simulator has been also established for control performance analyses using ADAMS and MATLAB/Simulink. Actual hardware of the motion simulator has been fabricated. Hardware test of the motion simulator has been tried to validate the design.

The lightweight, fast-moving design proposed for operations occurring within 5-10 years requires Soldiers riding as passengers in moving vehicles to perform operations previously conducted only in stationary environments. Operating under motion conditions can lead to performance degradations associated with physical perturbations and conflicting sensory inputs, which are associated with motion sickness. Full-motion simulators offer the flexibility to model and rapidly test multiple vehicle profiles and crew station design configurations while providing increased experimental control. However, a major concern is whether or not a simulator can evoke the behavioral responses observed in real life. This validation study compares the results of two complementary experiments that examined task performance while operators underwent either simulated or actual vehicle motion. Driving performance indicated differences between the experiments for several measures, while motion sickness questionnaire subscales indicated similar patterns of results across both experiments. Overall, support was found for both absolute and relative validity of using the simulator to examine issues related to motion sickness, but not for performance measures. Our results support the premise that simulators can be valuable for inducing specific types of real-life behaviors that will be inherent to designs proposed for future forces.
