Identification of Properties of Nonlinear Joints Using Dynamic Test Data

摘要: This paper presents a general purpose technique for identifying (extracting) the dynamic properties of nonlinear joints using test data. No theoretical model is required, only experimental data are needed identification. Because no assumption on jointly made, method applicable almost any type joints. In identification method, force at joint treated as an external and principle multi-harmonic balance employed. The force-response relationship then obtained. Various measurement errors in can affect accuracy this paper, efforts also devoted to understanding how affected by errors. Techniques improving discussed. verified studies. impact friction have been successfully identified.
