Project

Design and development of a negative stiffness mechanism based low-frequency passive vibration isolation platform

Indian Space Research Organization (ISTO) awarded a research project titled “Design and development of a negative stiffness mechanism based low-frequency passive vibration isolation platform” under SERB SURE scheme. The Principal Investigator (PI) for the project is Dr. B. Santhosh, Associate Professor , Department of Mechanical Engineering, Amrita School Engineering, Coimbatore and Co-Investigator for the Project is Dr. K. I. Ramachandran, Professor, Department of Mechanical Engineering, Amrita School Engineering, Coimbatore.

Project Summary

This project involves the development of a mathematical model for the six degrees of freedom vibration isolator based on QZS mechanism.  A computational framework based on harmonic balance method (HBM) will be developed to obtain the transmissibility of the isolator.  A prototype of the six degrees of freedom isolator based on negative stiffness will be developed and tested for low frequency isolation capability.
