AbstractIn the large telescope using hydrostatic bearings, what will happen if the deformation of supporting pad and sliding surface exceed expectation? Obviously, mechanical reliability of the telescope will be bad. In order to decrease this deformation of a large telescope, yoke of the telescope was optimized. The principle and process of this work and Finite Element Analysis (FEA) are introduced in detail. According to the FEA result, the deformation of supporting pad decreases 32% and sliding's decreases 36.7% after optimizing. The result shows that this work is effective to decrease the deformation of the two important surface and helpful to promote mechanical reliability of the telescope. © 2012 SPIE.; In the large telescope using hydrostatic bearings, what will happen if the deformation of supporting pad and sliding surface exceed expectation?
