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.

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.
