Ergonomic Analysis And Optimization Design Of Aerial Fire Truck Control Console

The aerial fire truck is an important equipment in high-altitude fire rescue scenarios,and its console is an important working space for controlling the work of the turntable,boom,and water cannon.The man-machine design of the console is an important part of the aerial fire truck design.A good man-machine design of the console is one of the keys to completing fire rescue and exerting the performance of the aerial fire truck product,which can improve the man-machine experience of the console and improve fatigue during operation,help to improve the efficiency and accuracy of operations.However,cost considerations and insufficient emphasis on human-computer design,the existing console designs of some domestic brands that aerial fire trucks have poor user experience,and there is some room for optimization in human-computer design.This article,based on the design project of aerial fire trucks,takes the control console of a certain type of aerial fire truck of XCMG as the research object,and conducts optimization design research based on man-machine simulation.The specific research work is as follows:(1)Starting from human-machine-environment and user behavior,summarize the optimized design process of user behavior,human-machine element analysis,scheme design,and result verification,construct the relationship between scenario,task,and posture,and summarize the typical posture of users in the human-machine environment of the console,laying a foundation for subsequent analysis.(2)Based on existing human body data,fit the human body data of various parts of the body with the height data to obtain the relationship between each body part and the height data,and then use the current human body height data to correct the size of each part,laying a foundation for subsequent analysis.(3)Create a 3D model of the existing console in the modeling software Rhino,import the existing model into the human-computer simulation software Jack,create a character model based on modified human body data,and perform human-computer matching.Perform human-computer simulation analysis of various typical poses for the existing situation.Analyze the defects of the existing console in terms of visibility,accessibility,and comfort,and establish a mapping relationship between humancomputer problems and human-computer elements,Provide guidance for subsequent targeted optimization design.(4)According to the two-dimensional bar model,the spatial layout of the console is optimized starting from the AHP point(Heel Point),and the range of the H-point,the position and size of the C-point(Center of the Eye Ellipse),the visual comfort area,and the arm comfort area are calculated,providing reference for subsequent seat layout,display screen layout,and joystick layout.(5)Calculate the weight of key type components in the console,and rearrange and design each component based on the importance and usage frequency.Optimize the main interface of the display screen according to the hierarchical relationship of page information.(6)Based on the previous research results,design a optimization scheme for the control console,create a three-dimensional model of the optimization scheme,and conduct man-machine simulation in Jack to verify the optimization effect of the optimization scheme in terms of man-machine aspects.The AHP-GEM fuzzy evaluation method was used to evaluate the original scheme and the optimized scheme,verifying the optimization effect of the optimized scheme in terms of usage,human-machine performance,and other aspects.The results showed that the optimized scheme had significant improvements in visibility,accessibility,usability,and interaction methods.This thesis has 70 figures,61 tables,and 95 references.
