Abstract

The invention provides a rail vehicle shielding grounding system, a wiring method thereof, and a rail vehicle. The rail vehicle shielding grounding system wiring method includes: constructing a three-dimensional model of the skin, grounding grid and wiring of the rail vehicle; based on the material impedance parameters and material electrical parameters of the rail vehicle, constructing the circuit model of the rail vehicle from the three-dimensional model and a three-dimensional electromagnetic simulation model; based on the circuit model and the three-dimensional electromagnetic simulation model, the grounding grid and wiring structure of the rail vehicle are optimized. According to the electromagnetic compatibility requirements of the carbon fiber composite material car body, based on the structural characteristics of the composite shielding grounding system, the composite shielding grounding system and electrical equipment wiring are considered as a whole, and the solution to the grounding network layout and its compatibility with equipment wiring can be obtained, forming Integrated ground wiring scheme.

Description

Rail vehicle shielding grounding system and wiring method thereof, rail vehicle technical field The present invention relates to the technical field of rail vehicles, in particular to rail vehicle shielding grounding systems and wiring methods thereof. French, rail vehicles. Background technique Carbon fiber composite material has excellent comprehensive properties such as high strength, low density and fatigue resistance, and has become a lightweight vehicle. The material of choice for body design and manufacture. However, the electrical conductivity of carbon fiber composites is lower than that of metallic materials such as stainless steel or aluminum alloys Several orders of magnitude, which leads to an increase in the impedance of the car body, which in turn causes the shielding effectiveness of the car body, grounding impedance, lightning protection, and current leakage. and other electromagnetic compatibility can be weakened. Therefore, it is necessary to con...
