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.

Aircraft simulation platform is the most important supporting technology in the aircraft development process. This simulation platform can be used for validating the design of subsystem and also it provides the necessary data for the Aircraft design. Wind has great impact on the flight parameter. In order to accurately simulate the wind model and calculate the flight parameters
a simulation modeling method for flight parameter simulation platform under wind field environment is established. Firstly
the various sub-systems which affecting flight parameters are analyzed
some mathematical models of the flight parameter simulation platform is established. Secondly
the atmospheric wind field is studied to analyze the impact on its trajectory. Then the model is built in the Simulink toolbox in the Matlab which is based on the principles of hierarchy and modularity
using C MEX S-function for the complex kinetic equations. Finally
when the models have been established
encapsulating models for several subsystem and assembling them for the Aircraft simulation platform based on the unified interface. The simulation tests (including the performance test of a certain gliding Aircraft
the wind influence test of a certain uncontrolled aircraft) prove the simulation capability of the platform
and its calculating step can reach 1 ms. Comparing simulation with field test data of a certain uncontrolled aircraft
it shows that the relative deviation of range is 0.47%
the relative deviation of maximal altitude is 2.1%. Taking relevant standards as a reference standard
it is demonstrated the platform is reliable
meets the engineering accuracy requirements. 2010 IEEE.
