摘要
为提高驾驶室舒适性及安全性,以国产某种收获机械驾驶室为研究载体,对人机工程学理论进行研究,结合中国人体尺寸数据,对驾驶室进行舒适性分析,改进其驾驶舒适跨点、驾驶座椅及驾驶操纵装置,优化各器件间布局配置关系。基于CATIA软件人机工程设计模块,对驾驶员驾驶姿态、操作可达性和视野范围进行模拟仿真,检验驾驶室设计合理性。对改进前后驾驶室舒适性进行主观对比试验,结果表明:随驾驶时间增加,驾驶员对两种驾驶室主观舒适性皆呈下降趋势;在0~20min驾驶时间内,对于两种驾驶室平均舒适性评价一致,在2 0~6 0 min驾驶时间内,改进前驾驶室驾驶员疲劳累积趋势加快;改进后的驾驶室总体布局合理,可满足对驾驶舒适性及安全性需求。该研究证明了人机仿真系统分析驾驶室舒适程度的可行性,为驾驶室的人机设计改进提供了参考依据。
In order to improve the security and comfort of driving cab , a kind of domestic combine harvester control cab was selected as research carrier , the ergonomics theory was studied , and the comfort of cab was analyzed based on Chi-nese human dimensions system .The comfortable driving across point , deriving seat and driving control device was de-signed , and the space-matching relationship of several devices was optimized .And then the driver posture , control panel ability analysis and vision of driver were simulated based on the man machine engineering design module of CATIA soft -ware and the rationality of cab designing was tested .The subjective comparative experiment was carried out .Test results showed that with the increase of continuous driving time , the subjective comfort of before and after improvement cabs all had decreasing trends;In the first 20 min driving time , the comfort evaluations for these cabs were consistent .In the ( 20~60 ) min driving time , the comfort evaluation for before improvement cab had an apparent decline .This paper could prove that using human-machine simulation system to analyze the comfort level of cab was feasible .It also provided the guidance and direction for the research of driving cab .
