| Abstract: | In view of dynamic response of generalized manufacturing space of super heavy duty horizontal boring and turning machine,the finite element model of the entire machine was established based on joint surface features.The modal and dynamic stiffness field for the entire machine in the generalized manufacturing space was analyzed.By considering the influence on the dynamic characteristics of the entire machine by large workpiece,the dynamic characteristics of the entire machine was comparatively analyzed by considering the effect of large workpiece.It provides the theoretical support for optimizing processing technology of the machine and improving processing accuracy of the machine. |
