Abstract
[Purposes]In situations where the speed level of railway lines and the installation accuracy of the overhead contact system are relatively low,the overhead contact system cantilever is often adjusted manually after on-site installation.In order to improve the construction efficiency of the overhead con-tact system,the simulation calculation theory of the overhead contact system is studied.[Methods]By es-tablishing a simulation calculation geometry and constraint model,and then building a overhead contact system cantilever simulation calculation platform,the platform is used to simulate and calculate the data collected on site.[Findings]After verifying the results of the simulation calculation,a simulation calcu-lation chart is generated.[Conclusions]By simulating and calculating the cantilever of the overhead con-tact system,it is possible to achieve precise and efficient processing of the cantilever pipe fittings under various working conditions of the overhead contact system,as well as one-time pre-installation,which ef-fectively reduces the construction period and cost,and improves installation accuracy.
