| Abstract: | LAMOST is composed of Schmidt correction board,focal system and spherical surface main mirror.The focal system consists of rotation structure,focal plate and support truss.The construction of focal plate and its support of LAMOST were introduced firstly.The coupling design of the focal plate and its support as well as the support truss and the rotation shaft were presented.Various unfavorable factors were discussed in the situations of preliminary testing or the working state of the focal plate and its support truss.The safety status of the coupling parts was checked in every limit unfavorable factors and the safety margin of coupling parts was given. |
| Keywords: | focal plate support stress margin of safety |
