Structural analysis for a lightweight model of large sheet material transfer robot

Abstract

Currently most of the products being produced have been developed in such a way as to develop an initial model for product stabilization and to improve various components of the product. Among the various components that make up the product, the main improvement method for the mechanical element is made by lightweight the product. Lightweight has become a major concern for the industry as a whole because of it is possible to obtain not only the cost required for the production of the product but also the energy saving effect necessary for the use of the product. As a general method of lightweight of the product, there are a method of reducing the volume by removing unnecessary parts of the existing product through a design change and a method of reflecting a material having a density lower than that of the material constituting the existing product. The above-mentioned methods for lightweight are factors affecting the structural stability of the product, and excessive lightweight affects the breakage and life of the product. Therefore, it is necessary to consider the utilization purpose and the use environment of the product when approaching to reduce the weight of the product, and verification of the lightweight model is required before the production. In this paper, we perform static analysis for structural stability of lightweight transfer robot that using in the tandem press line which produces the product through by multiple pressing process.
