From the standpoint of an engineer trying to assess the electromagnetic compatibility (EMC) of the equipment in a particular platform, the envelope of the emission spectrum is typically of greatest importance. It is desirable to have an automated method of reducing the large data set into a compact set that contains only those points which represent a close approximation to the spectrum envelope. An algorithm has been developed which performs automated reduction of emission data. The degree of reduction can be varied by the user through the choice of two parameters. Trial results show that the algorithm performs very well in approximating the envelope of typical emission curves.<<ETX>>","PeriodicalId":154914,"journal":{"name":"Proceedings of IEEE Symposium on Electromagnetic Compatibility","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130901456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Crosstalk on the cable harnesses is a potential problem for these typically tightly-packed cable bundles. Accurate computer modeling of the crosstalk allows for identification of potential crosstalk problems early in the design process. Decreased harness design time can be achieved by reducing the number of prototype harnesses constructed and the corresponding empirical testing. This translates into a direct cost savings for a given harness design. In this study, crosstalk modeling for an automotive wiring harness is evaluated. In general, harness data exist within a CAE/CAD vehicle layout tool. Information is usually not available, however, for the distribution of wires within a cross section of the harness. Assumptions then have to be made concerning the distribution of wires within a harness cross section. The assumptions made during this study are outlined and their impact on the predictions is evaluated. Computed results are presented and are compared to experimental data from prototype harnesses.<<ETX>>","PeriodicalId":154914,"journal":{"name":"Proceedings of IEEE Symposium on Electromagnetic Compatibility","volume":"2399 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127476488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A test procedure for evaluating electronic components in the powered state was already available.

Consequently, there was a definite need to develop a test procedure that correlated to real world results.

An analytical procedure has been developed that uses a combination of mathematical and numerical analysis to characterize the nonlinear electric field transients induced at the inner surface of long, thin-walled, cylindrical, electrically conductive, ferromagnetic shields by axially-directed short-duration surface current pulses along the outer surface. The peak value of the electric field transient and the time at which the peak occurs can be expressed in terms of effective permeabilities that depend on an applied pulse parameter that is a fundamental combination of the nonmagnetic problem parameters. The paper describes the practical implementation of the analytical procedure and discusses the results of numerical calculations for selected permeability representations.<<ETX>>","PeriodicalId":154914,"journal":{"name":"Proceedings of IEEE Symposium on Electromagnetic Compatibility","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114126001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
