摘要
为提升现有飞行模拟器座椅舒适度,减轻驾驶员长时间训练的疲劳感,基于自适应神经模糊推理系统(Adaptive Network-based Fuzzy Inference System,ANFIS)和理想压力分布(Ideal Pressure Distribution,IPD)构建一种飞行模拟器座椅舒适度评价模型.通过座椅压力分布采集系统获取压力分布数据,采用IPD将所得数据归一化作为模型输入数据,同时收集受试人员主观评分作为模型输出数据.采用非均匀有理B样条曲线(Non-Uniform Rational B-Splines,NURBS)对座椅进行改进设计,将处理后的试验数据通过ANFIS工具训练模型进行验证,并用评价模型评估设计方案及优越性.结果表明:该评价模型对飞行模拟器座椅舒适度有较好的预测能力,为提升飞行模拟器座椅舒适度提供指导和参考.
Abstract
In order to improve the comfort of existing flight simulator seats and alleviate pilots'fatigue experiences caused by long training sessions,a flight simulator seat comfort evaluation model was established based on Adaptive Neuro-Fuzzy Inference System(ANFIS)and Ideal Pressure Distribution(IPD).Seat pressure distribution data was obtained through the seat pressure distribution acquisition system.The obtained data was normalized into model input data using IPD,and the subjective scores of the subjects were collected as the output data at the same time.The optimization design was performed using non uniform rational B-spline(NURBS).The processed experimental data was trained and validated by ANFIS tool,and the evaluation model was used to evaluate the design scheme to verify its superiority.The results showed that the model had a good predictive ability for flight simulator seat comfort and could provide guidance and references for improving the comfort of flight simulator seats.
