Research of Ergonomical Comfortability of Getting on and off Vehicles Based on Subjective and Objective Combination Weighting
The comfortability of getting on and off vehicles directly affects the daily user's experience.In order to study the importance of each sub area of the comfortability of getting on and off vehicles,this article lists the main influencing factors.Firstly,scan the test vehicle,and extract the design dummy data of each vehicle to obtain objective data.Pearson correlation analysis is performed on the objective data,and the objective weight of the index is obtained using the entropy weight method,Secondly,based on the linear regression of subjective evaluation data and the Analytic Hierarchy Process of expert evaluation,subjective weights are obtained.The weight factor method is used to obtain the final subjective scores of each index and serve as a training set to combine and optimize subjective weights.Finally,the combined weight method is used to combine subjective weights with objective weights to obtain comprehensive weights.The results indicate that the subjective and objective evaluation system provided in this article has high reliability and can be better used for early planning and later design and verification.
