‘Damaru’ Inspired Lattice

Part of: GS Prelims and GS-I – Culture & GS-III – Sci & Tech

In news

  • IIT Kanpur Researchers have developed ‘Damaru’ Inspired Lattice that finds applications in stealth submarines and high speed trains.
  • Sponsored by: A SPARC project of Ministry of Education.

Key takeaways

  • With the use of a micro-structured hour-glass shaped meta-structure in the lattice unit, one can get a wider variation of propagation and stop bands.
  • Inspiration of the lattice has come from a two-headed drum called ‘Damaru’ or which is used in ancient Hinduism and Tibetan Buddhism. 
  • It is said that Lord Shiva has produced a special sound through this musical instrument to create and regulate the universe.
  • In this application, the researchers have also shown that the nature of stiffness of a vibrating medium could be altered drastically by controlling the lattice micro-structure from regular honeycomb to auxtetic honeycomb structure.
  • This has wide applications in the field of vibration isolation in high speed trains, stealth submarines and helicopter rotors.
