Abstract：To realize optimal design for structure and magnetic circuit of a pendulum tuned mass damper (PTMD) with eddy current damping, the overall structure of PTMD with a planar eddy-current damper (PECD) was studied qualitatively. The effects of magnetic field attractive force between PTMD and PECD on vibration frequency of PTMD, and those of magnetic circuit layout on equivalent damping coefficient of PECD were investigated using theoretical analysis, model tests and 3D electromagnetic field finite element simulation. The results showed that PECD should be installed at the bottom of the moving mass of PTMD, the magnetic field attractive force makes the vibration frequency of PTMD increase; the pendulum initial length of PTMD should be appropriately adjusted to avoid TMD detuning; the energy-dissipating effect of PECD is improved by reducing magnetic field gap, increasing steel plate thickness properly and optimizing copper plate thickness; along the moving direction of PTMD, adjacent permanent magnets’ magnetic poles need to be arranged in a staggered manner, their optimal interval is determined with FEM; while along the direction perpendicular to the moving direction of PTMD, adjacent permanent magnets’ magnetic poles need to be arranged in the same polarity manner, they are close enough.
