In the design of continuous bulk unloader, it is important to make clear the dynamic behavior of the structure in loading condition. The purpose of this paper is to show a theoretical analysis method of dynamic behavior of continuous bulk unloader in the condition. The analysis model is composed of unloader structure model, bucket chain model and digging resistance model. The digging resistance is divided into two components, front and side digging resistance. Each resistance is treated as external force acting on the structure via sprocket in the digging part of bucket chain. The validity of the analysis method has been confirmed compared with experimental result by an actual machine. The main result obtained are as follows: (1) The main components of vibration of the digging part are due to the periodical force acting between sprocket and chain link, and change of digging resistance. (2) The main component of vibration of the cab is due to the periodical force acting between sprocket and chain link.
