摘要

The paper presents the software DCAP (Dynamics and Control Analysis Package): a suite of fast, effective computer programs that provides the user with capability to model, simulate and analyze the dynamics and control performances of coupled rigid and flexible (NASTRAN interfaced) structural systems subjected to possibly time varying structural characteristics and space environment loads. It uses the formulation for the dynamics of multi-rigid/flexible-body systems based on Order(n). This avoids the explicit computation of a system mass matrix and its inversion, and it results in a minimum-dimension formulation exhibiting close to Order(n) behavior, n being the number of system degrees of freedom. A dedicated symbolic manipulation pre-processor is further used in the coding optimization. The modeling capability is completed with the possibility of user-defined software, allowing for modeling of specific control feature not directly included in the dynamic package's library. For the latter control modeling, a new interface is being a developed allowing to describe the user control directly by Matlab/Simulink blocks. An application example of 3D trajectory flight of a first stage launch vehicle with flexible time varying structural properties is presented.
