Robot Design of Underwater Building Surface Dredging - Structural Design

Abstract

In order to improve the efficiency of dredging, reduce the cost of dredging and ensure the safety of operation, this paper designs an underwater building surface dredging robot (hereinafter referred to as "underwater dredging robot"), which mainly includes the following aspects. The structure of underwater dredging robot is planned and divided into dredging system, walking system, driving system and support system. According to the actual work situation and the characteristics of each system, the scheme selection and structure design are carried out, and the overall layout scheme is obtained. The materials of the support system are selected and its force under different working conditions is analyzed. Through finite element analysis and modal analysis, it is verified that its reliability meets the requirements and there is no resonance phenomenon in the work.
