将优化设计方法与有限元法相结合，对开式机身进行了结构优化，提出了机身最佳截面形状，并给出了Ｊ２３－１０压力机机身的最佳截面尺寸。
The optimal design method is combined with the finite element method to optimize the structure of the open fuselage. The optimal cross-sectional shape of the fuselage is proposed and the optimal sectional size of the fuselage of the J23-10 is given.
