摘要
工程车辆驾驶室需满足不同体型驾驶员舒适性和视野要求,传统H点为基点设计需经常调整驾驶姿态来达到视觉要求且很难符合不同驾驶员特征。通过对工程车辆人机工程学设计标准研究及实验统计分析,将基于眼点定位驾驶室设计理念应用于工程车驾驶室设计。根据工程车辆视野特点,通过头包络线、前方视野及仪表台视野确定最佳眼点位置。搭建试验台,采集试验人员各部位在空间位置数据。根据统计数据,分析人体各部位关键点在二维、三维空间分布及关键点之关系。在保证眼睛处于最佳眼点位置情况下,通过数学表达式描述相应各部位在空间位置,以此确定座椅及其它相关装置空间位置。基于CATIA校核基于眼点定位设计方法是否能同时满足存在个体差异性的驾驶者视野及舒适性要求。分析结果可知,基于人机工程学和眼点定位可提高工程车辆的舒适性的设计水平而且对保障行车安全等方面都有重要的作用。
The cab of engineering truck meets the needs of different size cab drivers have a good comfort and a broad field of vision,but the traditional starting point of the H-point design often need to adjust the driver’s posture to achieve visual and difficult to meet the requirements of the different characteristics of the driver's body.Through analysis of human data experimental studies and the engineering truck ergonomics standards,the cab of engineering truck is designed based on eye location.According to the view characteristics of the cab,through the envelope,the front view and dashboard Perspective the location of the best eye point was determined.The test rig was built,and the location data in various parts of testers in space was collected.According to statistical data,the relationship between the various parts of the key points of the body in a twodimensional,three-dimensional space and the distribution of key points were analyzed.In ensuring the best eye point position,the various parts of the corresponding position in space was description by a mathematical expression,in order to determine the spatial position of the seat and other related devices.Finally,based on CATIA to check whether the eye point location can meet there are individual differences in driver vision and comfort requirements based on the design method.The results show that,based on ergonomics and eye point positioning can increase the comfort level of design and engineering of the vehicle to ensure traffic safety and other aspects have an important role.
