Research on Damping Characteristics of TiZrN Composite Coating Cantilever by Numerical Simulation Method

摘要

This paper studies on the mode analysis and harmonious response analysis of free layer damping cantilever beam (Ti-6Al-4V) by using numerical methods,discusses the vibration characteristics of the damping materials and gets the natural frequency.vibration mode,The von Mises Stress and amplitude-frequency characteristics curve. Otherwise,we extract the damping ratio and participation factor,so get the Loss factor at last. Natural frequency of Ti-6A1-4V plate after additional coating decreases and the ability of damping strengthens. Damping capacity increases with thickness of coating increasing.
