Abstract:
Rocket engine frame and force transmission structure, which are used to transmit the engineforce to rocket shell,are the key parts of launch vehicle structure system. In order to fully consider the coupling effect between the heavy rocket engine frame and the force-transmitting structure, find a reasonable transmission path and realize the efficient load-bearing, the joint optimal transmission path analysis and structural optimization design were carried out. Considering design requirements such as deformation, weight, design space and manufacturing constraints. For purpose of maximizing overall stiffness, the optimization model of the rocket engine frame and the force transmission structure was established, and the integrated optimization design was carried out. Besides, the influence of the parameters of the connection area between the engine frame and force transmission structure on the overall structure design was discussed, and relevant design suggestions were given.
