Space optical remote sensor is very important in many fields of science and military significance. It is widely applied.
Space optical remote sensor design and manufacturing require precision and stability. Focusing mechanics is an
important component of remote sensors. Focusing mechanics can guarantee the stability of the entire mechanics focusing
accuracy, therefore the stability of research focusing mechanics is very important. In order to guarantee the space optics
remote sensor focusing mechanics the stability, takes steps the space optics remote sensor focusing organization
mechanics characteristic analysis from the classics contact theory. This article uses international general non-linear finite
element analysis software ABAQUS to carry on mechanics characteristic analysis to the space optics remote sensor
focusing mechanics. First acts according to the focusing mechanics unique feature, carries on the finite element to the
structural model the grid division, the material attribute disposition and the boundary condition indeed grades. Then
establishment contact non-linear finite element model, and to focusing organization finite element model infliction unit
action. Like this contacts the result and the equivalent static analysis result which the nonlinear analysis obtains carries
on the contrast and the analysis. This article last count result modality is 90HZ, satisfies the space optics remote sensor
structure overall modality to request to be bigger than 50HZ.This article when carries on the dynamic analysis, extracts
the structure kinetic energy and the acceleration curve. In the dynamic analysis obtained transient response analysis
modality 70.5Hz, this also is bigger than 50HZ. The dynamic analysis indicated the structure dynamic stability has the
distinct enhancement, has provided certain foundation for the space optics remote sensor following development work,
reduced the overall system development cycle.
