AN INVESTIGATION OF RESPONSE CALCULATION FOR NOPD STRUCRURE BY ENDOCHRONIC THEORY
|
Abstract:
Non-obstructive particle damping (NOPD) technology is a new composite damping technology which is based on traditional particle damping and impact damping technique. NOPD technology has a good effect on vibration absorption. An incremental form of endochronic constitutive equation of discrete particle is derived by endochronic theory and penalty element is introduced to solve connect problem between the structure and the discrete particle. Computer simulation and experiment of response of NOPD structure are done on the basis of them. Results show that it is feasible to calculate response of NOPD structure by endochronic theory, which affords an effective analysis method for engineering application of NOPD structure.
