A Magnetic Suspension and Balance System (MSBS) provides the electromagnetic and non-contact support of a model in a wind tunnel to measure fluid-induced forces[1]-[7]. The purpose of this study is to measure the fluid-induced dynamic coefficients of an object suspended in fluid using the MSBS. We would like to propose a method for determining the effect of the fluid-induced dynamic coefficients by comparing the experimental results of the open-loop transfer function with the numerically simulated ones. In order to show the effectiveness of this method, we measured fluid-induced dynamic coefficients by exciting an object magnetically supported in water.
