‘Damaru’ Inspired Lattice
Part of: GS Prelims and GS-I – Culture & GS-III – Sci & Tech
- 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.
- 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.
