A Study on Measurements, Analyzes, and Evaluation of Motion-sickness Incidence and Ride-Quality

在船舶运动模拟器和客轮上，与许多受试者合作，进行了各种实验，以了解全身暴露于低频振荡引起的生理、生物化学和心理变化。对每名受试者进行问卷调查和血液检查，了解其健康状况。在振荡过程中，测量脑电图、心电图、心率、呼吸率、面部表情、面部表面温度等的变化。经过医学和心理科学领域研究人员的合作，对实验结果进行分析，得出以下结论。(1)通过脑电图、心电图等生理测量结果，可以评估晕动病的发生率。(2)一种利用面部表情变化评估晕动病发病率的方法。(3)本文提出了一种基于SD法问卷调查结果的运动病发病率和乘坐质量评价的层次模糊积分数学模型。(4)生活方式、个性/行为模式、应激状态、对晕动病的耐受性、身体状况等健康状况是与晕动病发病密切相关的内在因素。(5)本项目所开展的这种解决晕车发病机理的方法，对于解决晕车和乘坐质量的机理是必要的。

Experiments for obtaining physiological, biochemical and psychological change due to whole-body exposure to low-frequency oscillations have been carried out with the cooperation of many subjects on board a ship-motion simulator and a passenger ferry. Every subject was asked to take a questionnaire survey and blood test for investigating health condition. Change of EEG,ECG,heart and breathing rate, facial expression, face surface temperature etc. were measured during the exposure to oscillations. After the analyzes of experimental results by kind cooperation of researchers from medical and psychological science fields, following conclusions were obtained.(1) It may be possible to evaluate the incidence of motion-sickness by means of the results of physiological measurements such as EEG,ECG etc.(2) A method for evaluating motion-sickness incidence by using the change of facial expressions.(3) A mathematical model using the hierarchical fuzzy integral method was proposed for evaluating the motion-sickness incidence and ride-quality from the results of questionnaire survey of SD method.(4) The health conditions such as life-style, personality/behavior pattern, stress condition, tolerance to motion-sickness and physical condition, the internal factors, are closely related to the incidence of motion-sickness.(5) This kind of approach for solving the mechanism of motion-sickness incidence carried out in this project is necessary to solve the mechanism of motion-sickness and ride-quality.
