Table 1, the lower improved the quality of the hood structure from the 9.995kg to 8.538kg, 14.58% to reduce the bending stiffness, torsional stiffness and first-order mode has a different degree of increase

From Table 1, we can see that the hood structure from the original quality of 9.995 to 8.538 kg kg, reducing the 14.58 % of the bending stiffness, torsional rigidity and a first-order modal has a different degree of

May know by Table 1, after the improvement launch cowling structure quality reduces 8.538kg from original 9.995kg, reduced 14.58%, its flexible rigidity, the torsional rigidity and step modality all have the varying degree enhancement

Table 1 indicate that improved hood structure of reduced quality from the original 9.995kg to 8.538kg, thereby reducing the 14.58%, its bending rigidity and torsional stiffness and increasing first-order mode has different
