Much effort has been recently expended in the Dynamic Environments Community to attempt to address this problem. Recently, an Impedance Based Fixture Neutralization (FINE) technique has been proposed to this end; the technique has made positive strides to develop appropriate excitations to accurately mimic the field response in a laboratory setting. This approach uses only measured frequency response functions to formulate the differences in dynamic characteristics between the field and laboratory configurations. Impedance FINE has been shown to provide very good results but provides little insight into the intricacies as to how the structure frequencies and mode shapes determine the response. This work provides an alternate approach using the modal basis as a mechanism to identify the appropriate laboratory loads to achieve the same result in field and laboratory; this approach is referenced as the Modal FINE technique. The technique relies on prediction of modal forces to estimate the physical forces that achieve the proper input excitations in the laboratory that cause the DUT to have the same response observed in the field. One very important piece of the process is called the Modal Amplitude Contribution Matrix (MACM) which clearly identifies which laboratory modes are necessary to predict the field response from the field modes of the DUT. The technique is described in detail and both analytical and experimental configurations are used to demonstrate the accuracy of the technique.</p>\u0000 </div>","PeriodicalId":553,"journal":{"name":"Experimental Techniques","volume":"50 1","pages":"93 - 125"},"PeriodicalIF":1.9,"publicationDate":"2026-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147338615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is also seen between the field and laboratory due to the differing dynamic characteristics between field assembly loading and boundary conditions compared to the laboratory configuration. This work introduces a technique called Impedance Fixture Neutralization which customizes input forces to cause consistent responses for the Device Under Test across different vibration testing conditions. The customized force neutralizes the dynamic variations between configurations for the Device Under Test. The device responses can be replicated in several situations: when using a different fixture with the same attachment points, when the test article mounting location on the fixture changes, when the force location changes, or any combination of these situations. Impedance Fixture Neutralization uses the uncoupled dynamic characteristics of the test article and excitation fixtures to customize the input thereby causing the same test article responses between two mounting configurations (either field to laboratory or two different laboratory configurations). The application of the technique is shown using an analytical model of a two-beam system and analytically using experimental FRFs from plate and frame component hardware characterization tests. In both cases a device under test is attached to two test fixtures wherein the dynamic differences in the configurations are neutralized.</p></div>","PeriodicalId":553,"journal":{"name":"Experimental Techniques","volume":"50 1","pages":"59 - 91"},"PeriodicalIF":1.9,"publicationDate":"2026-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40799-025-00830-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147338588","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
