Research on the Structural Optimization Design of ER300 Palletizing Robot

ABSTRACT

4-DOF (Four degrees of freedom) palletizing robot is widely used in our country, which is playing a more and more important role in the logistics automation. The important indicators of ER300 palletizing robot performances include strength, stiffness, and ER300 palletizing robot weight, which mainly depend on the structural design of ER300 palletizing robot. So it is of importance to research on the structural optimization design by means of finite element analysis (FEA), ADMAS and Matlab. In this paper, the framework of structural optimization design is proposed. Secondly, taking ER300 palletizing robot as research object, its structure is described and the finite element (FE) model of the palletizing robot is developed for the finite element analysis. Thirdly, to ensure the reliability of the results of the analysis, stress and strain experiment is carried out to validate the analysis results. Finally, the structural optimization design of major parts has been completed. The results show that structural optimization design can reduce total mass of ER300 palletizing robot greatly by using the finite element analysis and optimization technology premised on the design requirements of palletizing robot such as stiffness, strength and so on, thus the structural optimization design can be achieved.
