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 comprises the following steps: constructing a skin, a grounding grid and a wiring three-dimensional model of a railway vehicle; constructing a circuit model and a three-dimensional electromagnetic simulation model of the rail vehicle by the three-dimensional model based on the material impedance parameters and the material electrical parameters of the rail vehicle; and optimizing a grounding grid and a wiring structure of the rail vehicle based on the circuit model and the three-dimensional electromagnetic simulation model. According to the electromagnetic compatibility requirement of the carbon fiber composite material vehicle body, based on the structural characteristics of the composite shielding grounding system, the composite shielding grounding system and the electrical equipment wiring are comprehensively considered, the grounding network layout and the solution of the compatibility of the grounding network layout and the equipment wiring can be obtained, and an integrated grounding wiring scheme is formed.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a rail vehicle shielding and grounding system, a wiring method thereof, and a rail vehicle. Background technique [0002] Carbon fiber composite materials have excellent comprehensive properties such as high strength, low density and fatigue resistance, and have become the material of choice for the design and manufacture of lightweight car bodies. However, the electrical conductivity of carbon fiber composite materials is several orders of magnitude lower than that of metal materials such as stainless steel or aluminum alloy, which leads to an increase in the impedance of the car body, which in turn causes electromagnetic compatibility such as shielding effectiveness, grounding impedance, lightning protection, and current discharge of the car body. Reduced performance. Therefore, it is necessary to construct a shielding and grounding system suitable for composite car bodi...
