“…Sim et al [8] established finite element modeling techniques for computational modal analyses by considering the liquid propellant and flange joints of launch vehicles. Baldesi [9] introduced some studies that the dynamics analyses of various types of launch vehicles were executed by using finite element analysis. Hutchinson and Olds [10] estimated the structural weight of the propellant tank of a rocket by establishing a simplified beam finite element model.…”

In this paper, the study focuses on influential factors of the vibration modal of the equipment bay of a carrier rocket and the structural improvement of the equipment bay by using finite element modal analysis. The finite element analysis focuses on the influences of the mass of the inertial bracket, the thickness of parts of the inertial bracket, and the stringer thickness on the first modal frequency of the equipment bay. As the analytical results show, the vibration displacement of mounting panels can be greatly reduced when the equipment bay is added with mass, and the vibration of the equipment bay with mass mainly occurs on the inertial bracket (without mass, the maximum vibration displacement occurs on the mounting panel); the top surface thickness of the inertial bracket has the maximum influence on the first modal frequency of the equipment bay, the stringer thickness and the side thickness of the inertial bracket have relatively high influence on the first modal frequency, the rib thickness of the inertial bracket has relatively low influence on the first modal frequency, and the beam thickness of the inertial bracket has the minimum influence on the first modal frequency.

“…The Marshall Aerospace Vehicle Representation in C II (MAVERIC II), also developed by NASA, is a modularized high-fidelity simulation software and appears in the work of Lu and Rao (2004). ESA, in turn, has developed a generic multibody flight simulator, capable of performing extensive launcher dynamics analysis (Baldesi and Toso, 2012). As an example of a commercial simulation tool, the company Astos Solutions has been developing the AeroSpace Trajectory Optimization Software (ASTOS®), a modularized software capable of performing trajectory simulation and optimization of launch vehicles (Cremaschi et al, 2010).…”

ABSTRACT:The use of digital simulation has become an essential activity during the development and operation of launch vehicles, due to the complexity of such systems. Of particular interest is the flight dynamics simulation, which investigates the behavior of the vehicle in flight subjected to forces and moments. This work presents a simulation tool suited to perform six degrees-of-freedom flight dynamics investigations of launch vehicles. Developed at the Instituto Nacional de Pesquisas Espaciais (INPE) and the Instituto de Aeronáutica e Espaço (IAE) in Brazil, the tool was implemented following the requirement for flexibility, so that it can be used to simulate different types of launch vehicles. The assessment of the vehicle performance and the vehicle payload capacity are some examples of analysis that can be performed with the tool. A modular programming strategy was employed to assure the tool flexibility. Therefore, the models presented in the tool were implemented as separate modules. The combination of these models can originate flight models of different launch vehicles. Two flight scenarios of Brazilian rockets were simulated and the results were verified against simulation tools already employed by aerospace community. The developed tool showed good agreement with respect to the simulators used to perform the comparison.
