摘  要:
In order to establish an accurate finite element model of header and get complete structural dynamic characteristics for combine harvester,the experimental modal analysis of type 4LZ-2.0 header was carried out.The modal parameters in each order were recognized by using ModalVIEW.Finite element model was analyzed by using UG software,and MAC value of experimental mode was calculated.The finite element model of header was validated.
