In order to meet the requirement of inertial navigation components and minimizing the system's weight
and topological optimization was conducted. Then
topological optimization and size optimization were conducted under conditions of random vibration and impact. Firstly
according to the dynamic characteristics of missile and requirement of inertial navigation system
the structure of inertial navigation support was designed according to types of missile connection and space arrangement of electronic components
the method of transforming multi-loading cases to multi-loading constraints was used to optimizing the size of the support under conditions of random vibration and impact. Comparing to the original support structures
RMS accelerations in installed points reduced by 25.2% under random vibration
the weight of optimal structures reduced by 28.1%
the structures also met the requirement of inertial navigation system under condition of impact. The support structure shows improvements in both dynamic characteristic and light weight comparing with the original one. 2011 IEEE.

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.
