Three-dimensional simulation of rotary latch assembly in seismic response and interactions

PDF Version Also Available for Download.

Description

The finite element method has been used to investigate the stress field in mechanical suspension systems. The critical seismic loads are depended on three-dimensional dynamic response of vacuum vessels and interactions of the equipment supporting structures to the vacuum vessels and supporting system. In this study of the optics assembly equipment (15 to 27 Hz), it was shown that the pressure vessel systems which supports the optics assembly systems (6.5 to 13 Hz) have significant influence in the seismic response of the rotary latch assembly. A potentially critical failure location is identified. An axisymmetrical elastic analysis predicts stress at the ... continued below

The critical seismic loads are depended on three-dimensional dynamic response of vacuum vessels and interactions of the equipment supporting structures to the vacuum vessels and supporting system. In this study of the optics assembly equipment (15 to 27 Hz), it was shown that the pressure vessel systems which supports the optics assembly systems (6.5 to 13 Hz) have significant influence in the seismic response of the rotary latch assembly. A potentially critical failure location is identified. An axisymmetrical elastic analysis predicts stress at the inner radius of the lower housing can be reduced by 60% with simple design modification. Use of three-dimensional dynamic model and static model to evaluate the combined complex stress permits prediction of the rotary latch assembly operating life and seismic safety.
