Polynomial-basis response surface method has some shortcomings for truss structures in structural optimization, concluding the low fitting accuracy and great computational effort. Based on theory of approximation, a based Multivariate Rational Function basis (MRRSM) is proposed. In order to further reduce workload MRRSM, focusing law between cross-sectional area nodal displacements structure, conjecture that determinant stiffness matrix corresponding elements adjoint involved displacement...
Space Solar Power Station (SSPS) is a giant spacecraft to collect space solar energy and transmit electric the ground by using wireless transmission technology. As concentrated power station, SSPS via Orb-shape Membrane Energy Gathering Array (OMEGA) system comprised of concentrator subsystem, photovoltaic array subsystem transmitting antenna subsystem. In this manuscript, comprehensive study on coordinate kinematic among subsystems carried out. Firstly, analysis dynamic are conducted....
A space solar power station (SSPS) has become a huge potential candidate to provide abundant and clean electrical energy for terrestrial users by collecting converting in space. In this paper, an innovative two-layer ring truss-based SSPS is proposed. It consists of the top layer concentrator-based spherical one-time reflection region, bottom radiator using symmetric or asymmetric cable networks, truss supporting structure, photoelectric conversion system, transmitting antennas. The...
The Space Solar Power Satellite is an ultra-large space structure, which collects sunlight directly in and then transmits it into the ground. Since idea was invented 1968, scientists around world have proposed several typical conceptual design models. Nevertheless, models not been implemented for technological, manufacturing, cost reasons. This paper presents a novel scheme with modular line-focused concentrators low concentration photovoltaic modules. First, mode analyzed optical...

The efficiency of a solar energy collection (SEC) is great significance to the power generation and overall space satellite (SSPS). Orb-Shape Membrane Energy Gathering Array (OMEGA) SSPS concept, inspired by Arbitrarily Large Phased (ALPHA) SSPS, designed for modular assembly, spherical condenser subdivided into many polygons. Deployable beams, surrounding these polygons acting as support system, affect not only SEC but also sphere's RMS structural displacement, mass, eigenfrequency,...
High-altitude nuclear electromagnetic pulse (HEMP) will lead to EED misoperation (such as early burst) or degradation of the performance and reliability failure) etc. This paper is mainly about injection effect test radiation high-altitude EMP on EED, tests are performed in typical HEMP environments. On this basis, researched analyzed EED. Analysis showed that ignition energy related with DC sensitivity EED; more insensitive is, bigger is. seriously affected, environment rise time getting shorter.
Abstract In order to analyze the shielding effectiveness of rocket projectile in electromagnetic environment, simulation model motor was established by using ANSYS HFSS software, calculated, and influence structural charactetristic parameters on analyzed, distribution law with frequency position were obtained, which provided support for evaluating environment safety rockets projectile.
