For the design of continuous bulk handling equipment, it is important to realize the dynamic behaviors. The purpose of this paper is to show a theoretical analysis method for the dynamic behavior of bucket elevator type continuous unloader which is one of typical continuous bulk handling equipment. Bucket chain and sprocket are represented as beam elements of finite element method. The dynamic force acting between sprocket and bucket chain is treated as external force to the structural parts via sprocket center. Under some basic operating conditions, the validity of this analysis method has been confirmed. The main conclusions obtainde are as follows: (1) The main component of vibration of digging part is due to the periodical force acting between sprocket and chain link. (2) The amplitude of vibration of digging part is reduced by decreasing impact coefficience between sprocket and bucket chain or by lightening bucket chain mass. (3) Decreasing bucketchain mass has little effect on reducing the delay time on boom slewing.
