The objective is to develop an integrated optimization framework to design complex space system. An improved collaborative optimization (ICO) strategy for complex design using hybrid optimization algorithm is proposed  which associates genetic algorithm (GA) with tabu search (TS). A multi-objective function with penalty terms for the systemlevel optimization and a relax factor for the subsystem optimization are adopted  which can avoid unsolvability or converging difficulty. The results demonstrate the applicability and effectiveness of the proposed design methodology. 2012 IEEE.   KW-output high beam quality diode laser array source (EI CONFERENCE) 会议论文  OAI收割 2012 International Conference on Optoelectronics and Microelectronics, ICOM 2012, August 23, 2012 - August 25, 2012, Changchun, China 作者:  Zhang J.;  Wang L.;  Wang L.;  Wang L.;  Liu Y. 收藏  |  浏览/下载：38/0  |  提交时间：2013/03/25 With the advantages of small volume  light weight  high efficiency and long lifespan  diode laser has been widely applied to industrial processing. Presently  for laser used as processing light source needs to amount to dozens of KW per cm2 of power density  how to increase power output and get smaller light spot for diode laser becomes a key problem. It is introduced that by designing beam shaping by ourselves and making use of optical system for beam blooming and focusing  808nm laser array composed of 20 bars eventually achieves the 1001.5w power output  coupling efficiency at 90%  11mm2 of light spot through experiments  which enables diode laser to be directly applied to cladding  welding and so on. 2012 IEEE.   The Coupling FEM and Natural BEM for a Certain Nonlinear Interface Problem with Non-Matching Grids 期刊论文  OAI收割 CMES-COMPUTER MODELING IN ENGINEERING & SCIENCES, 2011, 卷号: 73, 期号: 3, 页码: 311-329 作者:  Yang, Ju'e;  Yu, Dehao   |  收藏  |  浏览/下载：11/0  |  提交时间：2018/07/30 nonlinear interface problem  domain decomposition  natural boundary reduction  coupling  non-matching grids   Dynamic coupling analysis and modeling for stabilized platform of rolling-pitching seeker (EI CONFERENCE) 会议论文  OAI收割 2011 International Conference on Electric Information and Control Engineering, ICEICE 2011, April 15, 2011 - April 17, 2011, Wuhan, China 作者:  Liu H.;  Liu H.;  Liu H. 收藏  |  浏览/下载：13/0  |  提交时间：2013/03/25 Missile's attitude change will be delivered to visual axis through stabilized platform during maneuvering flight  and the missile vibration will be an interference source to visual axis stabilization. In order to solve this problem  the coupling relationship between missile attitude and visual axis is obtained by Coordinate transformation. When the seeker stably tracks a target  the angular velocity of visual axis in inertial space is zero  so the relative angular velocity of roll axis and pitch axis can be derived for servo control. According to Oura dynamics equation  the dynamic models of roll axis and pitch axis were established and kinetic equations of two axises were obtained. The dynamic models can provide theoretical basis to developing research of servo control system and structural optimization design of stabilized platform. Finally  some measures could reduce the dynamic coupling between the framework was given. 2011 IEEE.   Study on bandwidth mutual-benefit between the azimuth and pitch in an optoelectronic tracking system (EI CONFERENCE) 会议论文  OAI收割 MEMS/MOEMS Technologies and Applications III, November 12, 2007 - November 14, 2007, Beijing, China 作者:  Guo J.;  Guo J.;  Chen J. 收藏  |  浏览/下载：16/0  |  提交时间：2013/03/25 Two-axis optoelectronic tracking equipments generally use such mode that azimuth and pitch system are independently controlled. It leads to the two structures completely uncoupled  therefore  and reduces the state space dimension. But the main problem is that the rotational inertia of azimuth is much larger than that of pitch  it is an effective control mode to the two-axis photoelectric tracking equipments.  which leads its dynamic tracking performance is worse. So to find a more suitable mechanics and more effective control strategy is necessary. Considering the tracking ability  this paper designs BMC (bandwidth mutual compensation) to uniformly correct the error of both the azimuth and pitch system in real time  it is realized by cross coupling control to the azimuth and pitch. The simulation result verified that compared with classical uncoupling system BMS not only guarantees the state space dimension but improves systematic tracking performance about 2   Dynamics of free straight swimming of angulla angulla including forward, braking and backward locomotion 期刊论文  iSwitch采集 Journal of hydrodynamics, 2007, 卷号: 19, 期号: 4, 页码: 395-402 作者:  Hu Wen-rong;  Tong Bing-gang;  Liu Hao 收藏  |  浏览/下载：30/0  |  提交时间：2019/05/10 Self-propelled  Propulsive mechanism  Navier-stokes equations  Coupling problem   Multigrid algorithm for the coupling system of natural boundary element method and finite element method for unbounded domain problems 期刊论文  OAI收割 JOURNAL OF COMPUTATIONAL MATHEMATICS, 2007, 卷号: 25, 期号: 1, 页码: 13-26 作者:  Zhang, Sheng;  Yu, Dehao   |  收藏  |  浏览/下载：15/0  |  提交时间：2018/07/30 multigird algorithm  finite element method  boundary element method  coupling  unbounded domain problem
