【Abstract】 Aim To calculate the internal forces suffered by a rocket and its structure deformations. Methods An influence function of the internal forces and structure deformation caused by a unit force is established. Results Under the action of known crosswise forces the influence functions can be derived. Conclusion Influence function is the most evident description of the elastical characteristics of the structure. The results can be directly used to calculate strength, stiffness and aeroelastic stability.更多还原
