Abstract

A carbon fiber hexapod was used to install an optical telescope on the payload instrument module of a satellite. In order to reduce distortion stresses, titanium alloy brackets with flexure sections were employed to connect the end fittings of the carbon fiber struts. The design, fabrication and assembling of the carbon fiber hexapod were discussed. The developed hexapod passed the qualified level vibration test. The test results show that the hexapod could reduce vibration response in high frequency.
