基于静态体压分布的座垫舒适度影响因素分析

Influencing Factor Analysis of Cushion Comfort Based on Static Body Pressure Distribution

摘要:

行车过程中座垫舒适度会对驾驶舒适度和预防疲劳驾驶起到重要作用。驾驶人受到来自车辆、道路和环境等影响，体压分布特点与单一座椅时不同。从驾驶空间约束、驾驶视野和座椅几何尺寸三个方面，设计了驾驶人静态体压分布试验，建立了座垫舒适度主观评价逻辑回归模型。最后，深入分析了座垫软硬度主观评价结果与踝关节角度、坐高、座垫平均载荷之间的关系，为指导汽车座垫压力分布与驾驶人主观舒适度评价心理等研究提供依据。

Abstract:

Cushion comfort had a significant impact on driving comfort and preventing driving fatigue in driving process. When suffered factors from vehicle, road and environmental, characteristic of driver’s body pressure distribution was different from single seats. According to cab space constraint, driver's field of vision and size of seat, a driver static body pressure distribution experiment was designed and a logistic regression model was established. Finally, the relationship between cushion subjective comfort level and ankle angle, sitting height and cushion average load was investigated. This theory will provide a new basis for research about cushion pressure distribution and driver subjective comfort evaluation psychology.
