摘要：

This paper discusses an approach to evaluating the prediction accuracy of the output from a wheelchair-occupant simulation model in comparison with real-world exper-imental results. Different model setups, in which the wheelchair's occupant is supported on three types of seat cushions, are formulated with the model subjected to low-frequency vibration waves arising from the interaction between wheelchair tires and ground pro-file. The model's output, in terms of displacement response of the wheelchair and its occupant's body parts, is analyzed and validated for goodness-of-fit against the results of well-defined published papers. The analysis reveals that the occupant's torso receives the largest impact from vibration causing the organ to exhibit maximum displacement; and the foam-based cushion performs the best in helping to dampen the amplitude of displace-ment responses.
