[Data] Real Number Mode Curve Fitting Method and Its Applications
Analyzing the white body of passenger cars and pickup trucks! A comparison of the real mode method and the complex mode method was conducted.
The theory of curve fitting in experimental modal analysis has a long history during which various methods have been developed, and it is even said that there are no further mathematical advancements to be made. In this document, we introduce a real-valued modal curve fitting method that advances the assumption of real modes by using only the imaginary part of the FRF (or the real part when the FRF is in terms of velocity/force). Additionally, we applied this method to the white body of a passenger car and a pickup truck, and we present a comparative analysis of the results obtained from the real mode method and the complex mode method. We invite you to read it.
