Abstract: We have designed a precision machine for the manufacture of large-scale optical aspheric mirrors. The beam is one key component of the machine and it has a feature of three steps with the length of 3,100 mm. The technique driven at the centre of gravity has been used in the beam design. This feature makes a contribution to optimise force distribution, increase stiffness and reduce deformation so as to realise high accuracy.

 

Keywords: optimal design; finite element method; stepped beam.
