The present study proposes a method of estimating a compressed axial load on a clamped-clamped rod which has a stiffness support with the contact area. The stiffness support was assumed to consist of an infinite number of springs and it replaced with the Winkler-type spring for the purpose of this analysis. When estimating the axial load on the rod from the frequency equation, the unknown spring constant of the Winkler-type spring should also be obtained. In addition to the current experimental system, we created a new experimental system by attaching a mass to a point on the rod. Using the first natural frequency obtained by experimentation on these two systems, we calculated the axial load and the spring constant. As for the axial load which was estimated by using the proposed method, it found that the error was less than 10% compared with the actually acting axial load.
