Abstract
This report focuses on the development of a simplified light-weight damper consisting of a 'torus', a 'shaft', and a 'cylinder'. The shaft passes through the torus, which is inside the cylinder. When the shaft and the cylinder produce relative displacement, the torus rolls. The damper uses the generated rolling resistance for attenuation. This report describes a simplified light-weight damper and performance tests that confirm its effectiveness.
