Most conventional spacious solar photoelectric detection systems suffer from unexpected stray light. This paper demonstrates the effects on photoelectric detection system bring out by stray light. On this foundation
build up evaluation index of stray light system
to search the reasonable programme to eliminating stray light. A detailed telescope system geometry model was created
and scatter models were create for telescope and enclosure components. By the means of designing the structure of main baffle
baffle vane and the coating technology. In order to verify the prosperity of structure that designed
we utilizes software to analysis opto-mechanical model. we utilizes software to analysis opto-mechanical model. The simulations show that point source transmittance of the system is thus reduced by up to two orders of magnitude between 10-8 and 10-10. Meanwhile
the experiment obtains clean detection data which satisfies the system requirements. Stray light has been suppressed effectually
and so measurement precision was improved from detection graphics. (2012) Trans Tech Publications.

In order to rapidly develop the control system code of the Electromachanical Actuator(EMA)
the DSP development platform is established mostly based on the MATLAB
and the development metheod is researched.First
the DSP development platform archtecture in the environment of MATLAB is briefly introduced.And the principle of data exchange is showed.Then
the EMA hardware structure is necessarily explained
which one is for the developer to conveniently configure the system.Finally
the developer reasonably configures the DSP models used in the simulink and constitutes them to speed and position closed loop control system of the EMA
by using the RTDX and the MATLAB GUI. The EMA control system code will be debuged rapidly through this platform.The executed DSP code will be generated automatically.And the result of degugging would be showed on the MATLAB GUI.For generlly speaking
the difficulties of the EMA control system code development method is reduced and the development cycle is shortened through the MATLAB model.This system development method is fast and effective. 2011 IEEE.

Mathematical models of structural optimization were established for the cam wave generator
then a conceptual model
by integrally taking its static and dynamic performance into consideration
which satisfied the model acted by four concentrated forces
while the dynamic optimum design was carried out. The topology optimization of the cam wave generator was performed based on artificial material density method
was obtained. And the size optimization of the cam wave generator was also executed based on the zero-order method in software Ansys after setting up its parameterized model. The optimized results indicate that its final volume declines to 1284.217mm3 from its 1397.830mm3
which reduced by 42.18% than the original volume of cam (2221.224mm3). Simultaneously
the static analysis and modal analysis were implemented
and the results show that the static and dynamic performance complies with the design requirements
proving that the results of dynamic optimum design are reasonable. The optimized results in paper are realizable in engineering. And the study method provides not only a reference to decreasing design mass and lowering inertia of the cam wave generator
but also an important basis of lightweight design of harmonic gear drive. 2011 IEEE.
