摘要
目的为解决因车辆作业人员作业负荷大、频繁重复的不良作业姿势,所导致的作业人员患肌肉骨骼疾病的概率逐年增高的问题,对航空燃油供应系统清洗作业车进行人机设计研究。方法利用层次分析法计算作业人员在作业过程中产生不舒适行为的综合权重值并排序,经过实地调研与分析,获取车辆现有问题与作业人员身体负荷情况,结合虚拟仿真软件对问题进行真实性验证。根据验证结果,对车辆进行造型设计优化,并对设计方案进行合理性验证。结果作业人员在优化后的车辆进行作业时,其作业舒适性得到明显改善。结论优化了车辆的使用方式及作业空间布局,将作业空间划分为三个等级空间:第一等级空间距离地面790~1090 mm,第二等级空间位于距离地面1090~1490 mm,第三等级空间位于距离地面1490 mm~1830 mm,其中作业人员的最佳作业操作区域位于第二等级空间;此外将储存空间与风机箱相结合,使用滑轨结构横向打开储存空间,可以有效降低作业人员的作业负荷。
The work aims to study the human-machine design of cleaning vehicles for the aviation fuel supply system to solve the problem that the musculoskeletal diseases of vehicle operators are increasing year by year due to the heavy workload and frequent repetition of bad working posture of vehicle operators.The comprehensive weight values of the uncomfortable behaviors of the operators during the operation were calculated and ranked through the analytic hierarchy process.After field investigation and analysis,the existing problems of the vehicle and the physical load of the operators were obtained,and the authenticity of the problems was verified through the virtual simulation software.According to the verification results,the vehicle modeling design was optimized,and the rationality of the design scheme was verified.The operating comfort of operators was significantly improved when they were working in the optimized vehicle.The use mode of vehicles and the layout of work space are optimized,and the work space is divided into three levels:the first level space is 790-1090 mm from the ground,the second level space is 1090-1490 mm from the ground,and the third level space is 1490 mm-1830 mm from the ground,in which the best operation area for operators is located in the second level space.In addition,combining the storage space with the fan box and opening the storage space horizontally through the slide rail structure can effectively reduce the workload of operators.
