Pose accuracy is an important issue for parallel robot being used as mirror supporting system of telescope. One challenging topic is the accuracy synthesis which deals with the optimal design of the manufacturing and assembling tolerances of each component under the given pose accuracy. First
the error model of the 3-RPS parallel robot is built based on total derivation of the kinematic equations. And the error variable of each spherical or rotate joint can be expressed as a single boundary error parameter but not three independent position parameters. Then
the accuracy synthesis model is formulated taking the manufacturing costs as the optimization objective and the accuracy requirements as the constraint condition. Finally
the genetic algorithm is used to solve the optimization problem and a simulation example is given. The results show that the accuracy synthesis method based on manufacturing costs can satisfy the need of pose accuracy and is better for engineering application than the method based on error sensitivity. 2012 Chinese Assoc of Automati.

Space membrane reflector is very promised for optical quality application with the merits of ultra-lightweight and flexible. In order to improve the surface precision of membrane reflectors
the formation and surface shape error of a membrane at uniform load are studied based on the henky-cambell equations of circular membrane. The ANSYS software is used to build an optimization model of membrane reflector surface shape
in which the yield strength is the state variable
the surface load on ten concentric annular regions of the mirror is the design variable
and the minimum RMS between ideal surface and mirror surface is the target function. and the theoretical and experimental result show that RMS and PV of the optimized surfaces are reduced respectively than those before optimization. In a word
this paper offers the theoretical and experimental basis of the polyimide membrane reflector. 2011 IEEE.

On the analysis of the original data recorder
the stress wave theory is the elastic theory can explain the filter buffer question from the micro-small space
made several key problems clear when buffer and damping
from this designed a composite structure for vibration reduction
distinguished between a cushion theory and application field of stress wave theory
which made the dynamic stress of protected component down about one order of magnitude. Optimization with Isight and Ls-dyna
the traditional rigid spring-buffer model whose object is to reduce the impact of acceleration that can not accurately describe the elastic force of the part of the actual situation
the protected component's dynamic stress down about 69.3% and the data recorder's quality 300g lower
finally passed the Marshall Hammer test successfully. 2011 Trans Tech Publications.

In order to solve the registration problem of different source image existed on aerial image fusion
algorithms based on Particle Swarm Optimization (PSO) are applied as search strategy in this paper
and Alignment Metric (AM) is used as judgment. This study has realized the different source image registration of infrared and visible light with high speed
high accuracy and high reliability. Basically
with little restriction of gray level properties
a new alignment measure is applied
which can efficiently measure the image registration extent and tolerate noise well. Even more
the intelligent optimization algorithm - Particle Swarm Optimization (PSO) is combined to improve the registration precision and rate of infrared and visible light. Experimental results indicate that
the study attains the registration accuracy of pixel level
and every registration time is cut down over 40 percent compared to traditional method. The match algorithm based on AM
solves the registration problem that greater differences between different source images are existed on gray and characteristic. At the same time
the adoption of combining the intelligent optimization algorithms significantly improves the searching efficiency and convergence speed of the algorithms
and the registration result has higher accuracy and stability
which builds up solid foundation for different source image fusion. The method in this paper has a magnificent effect
and is easy for application and very suitable for engineering use. 2010 IEEE.
