Enhanced shock and vibration isolator for the attenuation of low-frequency vibration and high-frequency pyroshock loads
2012
Launch vehicles, satellites and aircrafts often experience harsh vibration and pyroshock loads during the flight
including maneuvering and separation events, which may cause the malfunction of equipped electronic devices.
Furthermore, this minor malfunction can generate catastrophic failure of the whole mission. To prevent malfunction of
the electronic devices from severe shock and vibration loads, elastomeric isolators are commonly applied between the
electronic device and the equipment bay structure in the aerospace fields. However, this rubber type elastomeric material
is vulnerable to the low-frequency vibration load which involves large amount of displacement due to its low stiffness.
Recently, the present authors proposed new type of isolator, called as pseudoelastic hybrid mesh isolator. This talk
introduces the key features of this new pseudoelastic hybrid mesh isolator which shows better isolation performance
throughout all frequency range than conventional isolators.
