In order to design a large aperture primary mirror with the diameter of 1150 mm
the parameters impacting on gravity deformation of the mirror were analyzed and discussed in detail
including material selection
diameter-thickness ratio
the number of the support points
location selection and lightweight structure
etc. A novel space mirror structure system was put forward
and its back was opened and supported by six points on back. The dynamic and static and thermal characteristics were analyzed based on the finite element method. Analysis results showed the surface figure accuracy reached to RMS 14.5nm under the action of gravity load along the optical axis direction and the first-order natural frequency was 214Hz which met to the designed indexes requirements.

Support structure of UAV (Unmanned Aerial Vehicle) engine is the important support for UAV engine
playing a support role and bearing extremely complex load
so its lightweight
strength and dynamic characteristics have a great influence on high performance of UAV. This paper focuses on UAV having the requirement of high performance and stability to the support structure of engine
and uses the software of MSC.Patran and MSC.Nastran and topology optimization criterion to lightweight design and analysis the support structure of UAV engine under the premise condition of existing constraints. Then the static strength and modal are analyzed for the result of lightweight design
and the strength of the model and dynamic characteristics are verified. (2012) Trans Tech Publications

Aimed at solving the practical problem about the difficult in the acquirement
the transformation and the sharing of the tacit knowledge
this paper have constructed a integrated context tacit knowledge modelCTKM
and the paper is based on the conclusion that knowledge is the product of certain context
the value of the knowledge depends on its context. Firstly
the model described in this paper fulfills online knowledge mutual platform
and it provide a support for the sharing transmission of the knowledge and the collection of tacit knowledge and knowledge context elements. After that
the paper constructs a context management model to finish the design of context recognition acquisition scheme and problem-based context modeling. Lastly
on the basis of the context model the paper fulfill the acquisition the expression
the sharing and the storage in the tacit knowledge management. CTKM model provide a solution of the integrated context for the tacit knowledge management and through the load of context elements achieve the effective sharing of the tacit knowledge. 2011 IEEE.
