Interval Scoring Method on Vehicle Seat Comfort Evaluation

Abstract

This paper provided an evaluation method to analyze the comfort interval of automobile seats. According to the theory and analytical procedure of interval parameter structure, based on the human pressure data and valuation results of a large number of automobile seat comfort subjective evaluation tests, the uncertain mathematical relations between objective data of automobile seat comfort test and subjective evaluation scores could be established. This mathematical relation was called interval relationship. The author established the seat evaluation database with a large number of test results, and developed an evaluation method of seat comfort interval with the application of the mathematical model. The Result of the analysis on the feasibility and effectiveness of the evaluation method proved that it could provide more reliable seat comfort evaluation results. The seat design engineer could use this method to replace the complex manual seat evaluation process. Meanwhile, the comfort score provided theoretical guidance for automobile seat design and improvement.
