The rocket structure is divided into thousands of small "elements." By solving the mass, damping, and stiffness matrices for these elements, engineers can predict how the entire structure will react to stress. Modal Analysis Modelling, Simulation, and Control of a Flexible Space

The vehicle is frequently modeled using the Euler-Bernoulli beam theory, where the rocket airframe is discretized into finite elements. Each element has associated mass and stiffness properties. The resulting equations of motion are typically second-order differential equations that include coupling terms between the rigid body degrees of freedom (pitch, yaw, roll) and the elastic degrees of freedom (bending modes). A critical aspect detailed in simulation manuals is the calculation of mode shapes and frequencies—the "modal analysis." This determines how the vehicle will naturally vibrate, which is essential for designing the control system. Access the technical paper on modeling and control at arXiv

: Significant complexity arises from coupling between the flexible body and separate dynamic elements:
