Mechanical damper for air pad instability |
摘要 |
In a diagnostic imaging apparatus, a stationary gantry (24) and a rotating gantry (22) are interfaced by a plurality of air bearing elements (40). Lower air bearing elements bear the weight of the rotating gantry (22) which induce air hammering phenomena at a characteristic vibration frequency. To counteract the air hammering, a damping assembly (44) is mounted to at least one lower bearing element (40). The damping assembly (44) includes a damping mass (46) and an elastomeric connector (48) that are tuned to a frequency near the air hammer frequency to absorb the vibrational energy and damp the air hammer vibrations.
