Damping Characteristics of Thin Metal Rubber Damper for Aeroengine Piping System

Metal rubber (MR) is a kind of nonlinear material of high damping ratio,and has been widely used in aircraft and spacecraft because of its marked damper characteristics.Several experimental investigations on basic performance of thin and small size MR damper has been carried out.We designed a one DOF system,and thoroughly researched the influence of MR dampers with difference parameters on the performance of the designed system.The results indicated that the formation density and thickness,the mounting tightness,the metal wire materials of MR have different effects on the damping capacity of MR.The higher the exciting force,the better the damping effectiveness.In working process,MR shows the soft behaviour,so the vibration,especially the intensive vibration,can be suppressed greatly,provided the construction parameters of MR are properly selected.
