| Abstract: | With secondary development via ANSYSTM and APDLTM, the parametric modeling is conducted on booms. Upon analysis of the impacts of different sectional parameters on boom stiffness, strength and stability, the major and minor factors on entire boom structural performance are determined for sectional size optimization. By treating boom stiffness, strength and stability as performance indicators, the performance parameters are optimized for boom structural model so as to obtain the optimal sections under different conditions. |

| Keywords: | secondary development performance parametric optimization optimal section |
