Eigenfrequency of object drops when it is submerged in the water compared to an air exposition. In this article the eﬀect of partial submersion on dynamic properties of steel plate is investigated. Changes diﬀer by a type of particular modeshape because of relative position of nodes and antinodes to free surface. Dynamic properties are influenced mainly by position of antinodes, in which maximal displacement occurs. Comparison of experiment, FEM simulation in ANSYS and custom code analytical solution is presented. Added eﬀects of fluid on the steel plate are discussed.
