According to the structure strength analysis on the feeding d ev ice, the secondary feeding part and pulley frame which are the main bearing parts were chosen to m ake strength analysis. The 3D model of the feeding device which is built in solidedge was introduced into ABAQUS. The fi­ nite elem ent model of the feeding device was built. The analysis of the feeding device was m ade in strong pulling condition. Results of relevant analysis show th a t,a n d the strength of the feeding device m eets the design requirem ents. Finally the strength analysis of the feeding device was verified by the performance test of physical prototype.
