반응표면법에 의한 레디어스로드 최적구조설계 및 피로해석

This paper aims to obtain the effect of lightweight on Radius rod. The response surface method used in thepaper is the statistical method. Optimization method is performed with the Radius rod using the lightweight material. Structural analysis is executed by using the ANSYS program to find static and dynamic responses. From this studyresult, it is verified that the response surface method has the advantage of optimum value in comparison with otheroptimization methods. The analysis is also performed by response surface method to derive optimal design values. Steelmodel and aluminium initial model are obtained by finite element analysis to clarify design criteria and the results arecompared with three models each other. The weights can be reduced by optimal design analysis results of these modelssimilar to those of existing products. The quantitative goals in this study can also attained through results of fatigue analyses. The reliability on optimal design of Radius rod can be improved by use of structural and fatigue analysis results.
