Ergonomic Research And Design Of Automatic Follow Maintenance Cart Based On Simulation Analysis And AHP-Entropy Weight Method

The maintenance cart is a kind of auxiliary equipment used by workers in the maintenance work.At present,there is a lack of research on the ergonomics of maintenance cart,which leads to musculoskeletal diseases.Based on this problem,this paper puts forward a comprehensive application of Jack simulation analysis and AHP-entropy weight method to the ergonomics research of the maintenance cart,based on which the development objectives and specific programs of the intelligent maintenance cart are proposed.The main contents of the article are as follows:(1)This paper first studied the main characteristics of man-machine maintenance work,and combined with the size of the human body,the size of the working space,maintenance personnel physiological characteristics and other content,elaborated the man-machine design principles of the maintenance cart design.(2)maintenance cart ergonomics(based on Jack)analysis,Jack is used to analyze labor intensity and joint force respectively.According to these two research contents,the functional design scheme and important man-machine size design scheme of the following handling of the maintenance cart are respectively proposed.(3)The comfort of tool layout(based on AHP-entropy weight method)was analyzed.Various maintenance tools were studied and analyzed based on AHP-entropy weight method,and a four-quadrant model of maintenance tools was established based on the importance and frequency of such tools.Finally,based on the four-quadrant model,a maintenance cart tool layout scheme was proposed.(4)Improve the design based on the man-machine design scheme.,the maintenance cart design scheme is proposed.Finally,experts were invited to evaluate the design prototype,and the simulation analysis(based on Jack)was carried out synchronously.According to the evaluation results,the ergonomics problems(maintenance work)have been effectively alleviated and handled.Jack simulation analysis and AHP-entropy weight method can be effectively applied in the ergonomics research of maintenance auxiliary equipment.
