Abstract

This paper is devoted to the modal analysis of a 3D bridge frame subjected to the weight of the materials to be moved during full-capacity transport, where the moving belt rests on suspended hanging roller sets from beams installed mounted in the middle of bridge columns, as an alternative instead of the underlying conveyor belt support frame. The scope of our investigation is limited to the vibration of the frame bridge when the loaded conveyor belt is substituted in the FE model with concentrated forces on the columns. The structure of the bridge frame is reused to assist the path of conveyor belts in the work area. The bridge frame, which consists of various structural steel beams, is modeled as a 3D frame using beam elements with various profiles. The purpose of finite element analysis is to provide a starting point for studies of the transient forced vibrations with the results of modal analysis.
