Research On Cargo Transportation Damage Analysis System Based On Digital Twin

Most manufactured products or commodities need to be transported to customers in the supply chain.Unreasonable loading scheme,uneven road surface,improper driving,vibration and impact,may lead to the goods occurred in different degrees of damage during transportation,which not only bring the losses to the consumers and logistics enterprises,but also will affect the timely production,manufacturing progress and beat,and causes road safety and pollution problems.Therefore,for specific transportation,trying to predict and analyze the damage of goods before and during transportation is of great value to ensure the safety of manufacturing and logistics.In view of this,this thesis combines the prediction advantage of digital twin technology,carries out the research on the cloud service system for damage analysis of the goods delivery based on digital twin,establishes a twin model for damage analysis of goods,and realizes the advance prediction of damage of goods during transportation,which can guide the completion of reasonable and safe loading,packaging design,driving control,ensure the safety of production,enhance the level of service of transportation,and promote the intelligent transformation of transportation.Firstly,the types of damage that the goods may suffer during transportation are analyzed,and the requirements of the goods transportation damage analysis system based on digital twins are put forward.On this basis,the functions,operating procedures and system structure of the digital twin-based cargo transportation damage analysis system are designed.Secondly,Aiming at the static damage and dynamic damage that the goods may be suffered by during transportation,the construction methods of the goods twin model,static damage twin model,and dynamic damage twin model are studied.Through the finite element software ANSYS,the static and dynamic damage analysis methods for the packing layout twin model are studied,and the static and dynamic damage of the packing layout twin model during transportation are predicted.Finally,the data of the static and dynamic damage analysis results are stored in the My SQL database;the visualization method of the packing layout twin model and the visualization method of the damage analysis results on the client side is established by using the Three.js web-side 3D visualization technology.The implementation method of the main functions of the cargo transportation damage analysis system based on digital twin is studied.The interface structure,database,and technical architecture of the system are designed;A web server is built through Flask and Python.My SQL database is used to store system data.The client interface is built by Hyper Text Markup Language(Hyper Text Markup Language,HTML),Cascading Style Sheets(Cascading Style Sheets,CSS),and Java Script language.The system functions are realized by Py MAPDL,Three.js,Phisics.js,dat.gui.js and other libraries.All functions are integrated into the digital twin-based cargo damage analysis cloud service system,so that relevant transport personnel only need to upload the corresponding packing layout result data,and through the simulation analysis of the system,they can predict the static and dynamic state of the packing layout twin model damage and stability conditions to guide the actual physical packing operation.The function of the system is demonstrated by an example,which proves that the system can effectively guide transportation personnel to complete the safe packing layout.
