Abstract: As an important part of freight transportation, railway freight loading and reinforcement mainly adopts manual drawing, manual calculation and other traditional methods, which is poor visualization and low efficiency. This article used WebGl, 3DMax, Rhino and other visual simulation modeling technologies, combined with the theoretical knowledge of load and reinforcement business, to implement the load and reinforcement scheme matching and automatic processing of generation. On the basis of providing an intuitive display of the loading and reinforcement scheme, it meets the requirements of the business personnel for interactive operation of the display scheme, and makes the business personnel have a more intuitive understanding of the loading and reinforcement scheme. It is of great significance to improve freight operation efficiency and promote paperless and intelligent development of railway freight production.
