Under the I-DEAS environment,the finite element models for both upper and lower steel structures of the ultra-large bucket-wheel stacker and reclaimer are built respectively,for analysis of stress,deformation,and natural mode, etc.The paper describes the main ideas and process of finite element analysis for bucket-wheel stacker and reclaimer,and provides key analysis points and precautions in aspects of selection of working conditions,load calculation,building of fi-nite element model,and post treatment of the results,etc.
