Simulation test system of CCD signal processor based on FPGA is proposed. Field-programmable gate array (FPGA) is applied as control processing core and used in the aerospace upgrade screening of industrial grade signal processor. The system functional composition and working principle were introduced in detail. Actually evaluation and testing system was completed with integrating the forty signal processor in a single board. The system has been successfully applied in the dynamic build-in screening test of industrial grade signal processor XRD98L63  the system work stably and reliability. Test result is zero on the nonconforming product rate  satisfying the qualification that single batch screening nonconforming rate is less than 5%  build-in screening of industrial grade components for the space load applications is implemented.

In order to realize miniaturization and light weight of the strap-down inertial navigation system  and then to make sure that it works well under random loads  optimal design is applied to the strap-down inertial navigation support with the methods of topology optimization and size optimization. Firstly  based on the installation requirement of devices and connection requirement of the support and the carrier  the initial structure of the support is designed. Topology optimization with FEA software ANSYS is adopted on the initial structure to get the basic one. Then 5 critical sizes are chosen as design variables  and the support structure is optimized by means of size optimization to reach light weight with satisfying the requirement of dynamic stiffness. Finally  random vibration analysis is applied to the initial structure. In the mean time  random vibration test is carried out to qualify the analysis method. After the qualification  a random vibration analysis is applied to the optimized support structure to get the rms of displacement response and acceleration response of the support to validate whether the optimized structure is appropriate. The results indicate that the dynamic stiffness of the optimized support structure satisfies the design requirements  and its weight is lighter 49.38% than that of the initial one. This research can be a reference to the structure design of supports under random loads  and the result has been applied to the development and manufacture of a prototype aerocraft. 2010 IEEE.
