High precision structural Finite Element Analysis (FEA) results are required in the development of a remote image sensor. HperMesh and MSC. Nastran are employed in the image sensor structural FEA. This paper discusses some technical issues about the Finite Element (FE) modeling of the image sensor. In order to obtain authentic analysis results
the part-to-whole handling schema
i.e. handling method and research work is implemented in a small part of the model firstly and a revised method is used in the whole structural in succession
has been proposed. Some emphasis is mainly put on the FE handling of bolted joint
bearing and inter-element connection. The interface handling methods
such as CBEAM plus partial MPC bolted joint model
hybrid element bearing model and RBE3 beam-to-solid connection
have been produced and successfully implemented in the image sensor structural FEA. 2010 IEEE.
