STUDY ON DAMPING PERFORMANCE OF HYPERBOLOID DAMPER WITH SMA-NEGATIVE STIFFNESS

To improve the limiting capacity of isolation bearings and reduce residual deformation, a new material shape memory alloy (SMA) was introduced into the damping device.SMA shape memory materials have shape memory effect, superelastic effect, and damping properties of metal alloys.Although the SMA isolation bearing can improve the self-resetting abil

A hydraulic pipe is a basic component of the aero hydraulic system, while high pressure and high speed lead to the enhancement of multiple field coupling effects, such as the structure, fluid, heat, and sound of the aero hydraulic pipe.A larger elastic deformation of the pipe and the more common unsteady flow of fluid can aggravate the vibration an
