基于烦恼率模型的船舶振动、噪声舒适度评价

Evaluation of ship vibration and noise comfort based on annoyance rate model

为了评价船舶振动、噪声舒适度,提出基于烦恼率模型的评价方法。基于适应性理论,考虑船舶自然环境的复杂多变性,从生理、心理角度揭示人对振动等不舒适因素反应的不确定性。利用一般的振动舒适度指标——振动加速度,考虑船舶不同区域乘客和船员的振动舒适度感受,以及不同的人对同一振动的舒适度感受差异性,采用集值统计法得到烦恼率算法。实船测试和问卷调查验证了该模型的可行性和有效性。

In order to evaluate the ship vibration and noise comfort,an evaluation method based on the annoyance rate model is proposed.Based on the theory of adaptability,considering the complex variability of the natural environment of ships,the uncertainty of the reaction of people to the uncomfortable factors such as vibration is revealed from the physiological and psychological point of view.Based on the general vibration comfort index-vibration acceleration,considering the vibration comfort of passengers and crew in different areas of a ship and the different experiences of different people on the same vibration,the annoyance rate algorithm is obtained by the set-value statistics.The feasibility and validity of the model are verified by real ship test and questionnaire survey.
