摘要
越障导线飞车的安全性体现在结构强度与带电作业人员体表场强防护两方面。运用有限元分析方法,选取越障导线飞车作为研究对象,考虑其在承载最大载荷的作业工况下,利用SolidWorks构建仿真模型,然后采用ANSYS Workbench、COMSOL Multiphysics分别对越障导线飞车架体从应力与带电作业人员体表场强分布进行仿真分析。分析结果表明,所构建的飞车模型在负载最大允许工作载荷(300 kg)时,其应力分布满足载荷要求;同时,在典型带电作业工况下,飞车内作业人员体表场强远低于带电作业规定的防护标准。
The safety of the obstacle-crossing conductor speed car is embodied in two aspects: the structural strength and the field strength protection of live workers. Using finite element analysis, the obstacle-crossing conductor speed car is selected as the research object. Considering the maximum load-bearing operating conditions, the simulation model is built with SolidWorks, and then ANSYS Workbench and COMSOL Multiphysics are used to simulate and analyze the stress and the field intensity distribution on the body surface of live workers. The analysis results show that when the maximum allowable working load(300 kg) is applied to the constructed speed car model, the stress distribution of the flying vehicle meets the load requirements. At the same time, the surface field strength of the operating personnel in the speed car is far lower than the protection standard specified for live operation.
