Problems solved by technology
Due to the complexity of the electromagnetic environment inside the equipment, equipment manufacturers often use special cables with strong electromagnetic compatibility as transmission lines, such as braided shielded cables and twisted-pair cables. Traditional methods are mostly for crosstalk analysis of bare wires. Therefore, it is not enough to solve the problem of using a special cable structure; secondly, for the uncertainty analysis of the crosstalk of the wire harness, the traditional technology is a function of a distribution type of the input variable, but the input variable may belong to multiple distribution types in the actual situation
[0003] The current braided cable design cannot meet the EMC design requirements

The invention relates to a braided shielding cable design method and device, computer equipment and a storage medium. The method comprises the following steps: calculating to obtain transfer impedance and a parasitic parameter matrix of the braided shielding cable according to structural parameters of the braided shielding cable, wherein the structural parameters of the braided shielding cable comprise uncertainty parameters; establishing a crosstalk calculation function of the braided shielding cable according to the transfer impedance of the braided shielding cable and the parasitic parameter matrix; constructing a proxy model of a crosstalk calculation function of the braided shielding cable, wherein the proxy model comprises a random input variable; and quantifying random input variables in the proxy model to obtain a global sensitivity index of each random input variable. By adopting the method, the proper structure parameters of the braided shielding cable can be selected according to the global sensitivity index of each random input variable, and the electromagnetic compatibility design requirement of the braided shielding cable is met.
Description
technical field [0001] The present application relates to the technical field of electromagnetic compatibility, in particular to a design method, device, computer equipment and storage medium of a braided shielded cable. Background technique [0002] There are deficiencies in the traditional technology in the electromagnetic compatibility design of the wiring harness. Due to the complexity of the electromagnetic environment inside the equipment, equipment manufacturers often use special cables with strong electromagnetic compatibility as transmission lines, such as braided shielded cables and twisted-pair cables. Traditional methods are mostly for crosstalk analysis of bare wires. Therefore, it is not enough to solve the problem of using a special cable structure; secondly, for the uncertainty analysis of the crosstalk of the wire harness, the traditional technology is a function of a distribution type of the input variable, but the input variable may belong to multiple dist...
