Satellite & Space

The light-weight equipment used for space vehicles and satellites must be strong and able to withstand harsh environments and extreme load exposures during launch. These light-weight structures are prone to vibration so consideration to shock and vibration issues is vital when designing these devices.

Simulation is a valuable tool for quantifying designs and systems destined for flight.

Managing lightweight structure resonances can be a major challenge.  Xi’s engineers attempt to consider all possibilities from traditional stiffening, springs and dampers to active control systems such as Macro Fibre Composite (MFC) piezo actuators.  These are specially formed piezo arrangements that can produce almost double the strain actuation and four times the strain activation density of traditional through plane poled ceramic piezo.  With appropriate control these can be applied to light-weight structures to damp and suppress otherwise damaging resonant, and even forced vibration, behaviour.

Xi are able to help clients consider the effects of structures used in movement (flight) and the effect of moving machinery within the structure.
