In order to efficiently and accurately design pipeline of the air braking system,taking the engineering ve-hicle air brake system using JZ-7 air brake as an example,the composition and working principle of the air braking system are introduced.Based on the schematic diagram of the air braking system,a pipe layout design method based on a three-dimensional model for laying pipelines is adopted to design a three-dimensional diagram of the air brake system,generate a engineering drawings for pipeline layout,and verify engineering drawings for pipeline layout on a JJC type catenary maintenance vehicle.The verification results show that the engineering drawings for pipeline layout designed based on three-dimensional model for laying pipelines is accurate,and using the engineering drawings for assembling pipeline can improve on-site assembly efficiency and reduce pipeline interference.
