In this paper, we discuss dynamic stability analysis of an elastic rod with lumped masses and their weight subjected to nonconservative forces by the integral equation method. We have already proposed a basic analysis procedure using boundary element method for a regional division type. The effectiveness of the procedure was confirmed by numerical analysis examples of a lot of elastic stability problems. This procedure is applied to the dynamic stability analysis of an elastic rod with lumped masses and their weight under follower force. The analysis model is the rod of the cantilever beam type with one lumped mass or two lumped masses and their weight. The follower force sets the Beck type and Leipholz type load. The internal damping term is included to the governing equation. One of the numerical solutions is compared with analytical solution of Nikolai's model and Leipholz's approximate solution. The characteristics of mechanical behavior are shown from the obtained numerical solution.
