A Novel Approach for Flexible Body Dynamics Computation via Synthesizing Incremental Motions in Reconfigured Inertial Frames

Abstract

A novel approach is presented for computing flexible body dynamics based on conventional structural dynamics models. This approach innovatively captures the rigid body motion component embedded within a flexible body's movement, generates and synthesizes single-step responses in a sequence of reconfigured inertial frames that follow the rigid body motion. By doing so, it effectively bypasses the complexities associated with modeling flexibilities and formulating highly nonlinear coupled motion equations. In addition to improving predictive accuracy, this approach offers valuable insights into the interaction between rigid body motion and structural vibration. By bridging these two aspects, it advances the understanding of flexible body dynamics and delivers a precise, efficient simulation framework for a wide range of engineering applications.
