Currently a finite element model to investigate
the thermal and launch stresses on a fine-steering and alignment mirror
is being constructed for Left Hand Design
Corporation in Boulder, Colorado. The fine steering mirror
is a small mirror (varying sizes of approximately 1.5 - 5 cm diameter)
with electromechanical actuators which can control the mirror at a bandwidth
up to 4000 Hz. This is useful for applications such as:
-
Image Motion Compensation
-
Earth observation from orbit
-
Instrumentation equipment
-
Infra-red inspection
-
Laser surgery

The design is likely to be used for applications such as the Space
Interferometry Mission (figure 1) as well as other line-of-sight stabilization
applications. For more information about the functions, performance
and applications of the Fast Steering Mirror, please see the product
information from LHDC.
Unfortunately, screen shots of the finite element analysis are not
available to the public because they contain proprietary information.
An example of COSMOS/M output is shown figure 2. Please contact
either Willard Simmons
or Dale Lawrence if you
have questions about this project.
The software being used is COSMOS/M
from Structural Research and Analysis Corporation. |
