摘　　要：针对目前主要从姿势角度和主观评价两方面对驾驶姿势舒适性进行评价,未能在更深层次上揭示驾驶姿势舒适性的机理,且通过主观评价构建的姿势不舒适度模型的实用效果不理想,提出了一种客观评价方法。首先建立了驾驶员的人体生物力学模型;接着设计仿真方案,进行肌肉分群,设定评价指标,并定义姿势变量;最后通过仿真,初步获得驾驶员坐姿和驾驶室布置参数对驾驶员人体生物力学负荷及其分布的影响规律。In view of that current evaluations on driving postural comfort conducted from the aspects of postural angles and subjective evaluation can not reveal the mechanism of driving postural comfort in depth,and the practical effects of postural discomfort model created by subjective evaluation is also not so good,an objective evaluation method is proposed. Firstly a human biomechanical model for driver is built. Then simulation scheme is devised,muscles are classified into groups,evaluation indicators are set and postural variables are defined. Finally a human biomechanics simulation is performed and the law of the effects of driving posture and the packaging parameters of cab on the human biomechanical loads and their distribution of driver is preliminarily obtained.
