Abstract:
In this century, the development of space technologies has substantially increased. As space launchers improve their performance, space agencies have adopted the use of smaller satellites. Modern space platforms have structural requirements that entail the use of an optimized methodology for automating the creation of satellite designs. Parametrization can play a crucial role in this task. The aim of this paper is to parametrize a structural plate used in a microsatellite preliminary structure and analyze its mechanical behavior under the application of static forces.

In this paper a method for the parametric sensitivity of acoustic-structural coupled systems is presented. The symmetrical Eulerian formulation is applied in order to calculate the coupled frequencies and modes. From a state space formulation of the problem a sensitivity algorithm is developed to obtain the derivatives of the coupled frequencies and modes of the system versus a design parameter vector. The algorithm is based on the properties of the complex conjugate eigenvalues obtained from the solution of the state space equation. Numerical examples from an acoustic rectangular cavity backe

Development of the optimal structural arrangement for a reflector with the aim to improve its mass and design is of importance due to the necessity to increase areal density and decrease rigidity of the modern space antennas vehicles. Currently, CAE-systems allow to design reflectors using both traditional methods, for example, parametric optimization, and methods which are innovative in this field, such as topology optimization. The paper compares two methods of the structural arrangement design for a thin dimensionally stable reflector operating as part of a geostationary spacecraft: paramet

Abstract:
Static redundancy does not ensure structural redundancy in cases where the collapse mechanism involves instability. Structural redundancy is defined here as the ability of the structure to sustain its design load with the loss of one or more critical elements. The parametric investigations on a square on square double-layer grid presented here, suggests that the loss of one critical member from this type of structure typically entails a loss of 20% to 30% of load carrying capacity. To allow for structural redundancy, as well as for loss of carrying capacity due to the effect of imperfections,

The design cycle of membrane structures consists of three interactive and highly non-linear disciplines. Formfinding is performed in order to find a geometry that allows the prestressed structure to carry loads through tension only. Once a formfound geometry is set, structural analysis needs to assess the structure's safety and usability. The most challenging step is the cutting pattern generation, which aims at finding the planar pieces which can be elevated to build spatial membrane structures with a minimum deviation from the desired shape and prestress state.<br/> Isogeometric B-Rep

Abstract:
Abstract Parametric Optimization is used to solve problems that have certain design variables as implicit functions of some independent input parameters. The optimal solutions and optimal objective function values are provided as functions of the input parameters for the entire parameter space of interest. Since exact solutions are available merely for parametric optimization problems that are linear or convex-quadratic, general non-convex non-linear problems require approximations. In the present work, we apply three parametric optimization algorithms to solve a case study of a benchmark stru

Abstract:
Abstract To improve the deployed stiffness and mass efficiency of pre-tensioned spacecraft structures, the efficacy of cable-stayed configurations is analyzed in this paper. The reference structure is a deployable array wing that supports a series of RF panels for space-based antenna applications, and it is designed to be z-folded under stowage. Due to the significant mass of the panels and the large span of the array wing, the entire structure is susceptible to low frequency excitation. Lightweight pretensioned cables that elastically support and stiffen the array along its span are found to

Abstract:
Abstract The feasibility of a hybrid PMOR-SDP approach, that combines semidefinite programming (SDP) and parametric model order reduction (PMOR) was investigated. When an optimization problem comprises of a linear objective and linear matrix inequality constraints, SDP provides an efficient algorithm for arriving at a globally optimum design. This is achieved by solving a linear systems of equations that simultaneously satisfies the optimality conditions of the primal and dual problems. Weight minimization of a structure subjected to frequency or buckling constraints is amenable to this approa

Abstract:
&lt;p&gt;In the 21st century, digital design tools, which are interfaced with the CNC technology, have opened the new opportunities that not only are shaping structural objects, but also interfering with the urban tissue. The first part of the paper defines the main features of the “green” approach to the built environment. Selected examples illustrate diverse approaches to designing footbridges, and what combines them is the use of digital tools, especially the topological and analytical ones, in shaping and constructing parametric forms. The second part presents how structural engineers and

Abstract:
This paper applies new techniques and metrics to analyze Ecuador's past record of and future opportunities for structural transformation. Ecuador's export dynamics and the emergence of new export activities have been the historical drivers of the country's growth, but recently Ecuador's export basket has undergone little structural transformation. The same broad sectors continue to dominate, and the overall sophistication of the export basket has actually declined in recent years. In order to consider why movement to new, more sophisticated export activities has lagged in Ecuador, we examine e
