Title:
ブラシシールの固有振動数を測定するための装置及び方法
Document Type and Number:
Japanese Patent JP2004510969
Kind Code:
A
Abstract:
A brush seal segment is mounted within a pressure vessel and against an arcuate surface of an element to provide a seal between regions on opposite sides of the seal at different pressures. By vibrating the vessel through a range of frequencies, natural frequencies of the brush seal under pressure loading can be ascertained. Additionally, by adjusting interference between the arcuate surface and the bristle tips, natural frequencies of the brush seal under various interference loadings can likewise be ascertained. The pressure vessel has mounts for attaching the vessel to a shaker table to facilitate vibrating the vessel through the range of frequencies.
