Title (EN) APPARATUS AND METHODS FOR DETERMINING NATURAL FREQUENCIES OF BRUSH SEALS
(FR) APPAREIL ET PROCEDES DE DETERMINATION DE FREQUENCES NATURELLES DE BALAIS D'ETANCHEITE
Abstract: front page image
(EN)A brush seal segment (24) is mounted within a pressure vessel (10) and against an arcuate surface (44) 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 acruate surface and the bristle tips, natural frequencies of the brush seal under various interference loadings can likewise be ascertained. The pressure vessel has mounts (50) for attaching the vessel to a shaker table to facilitate vibrating the vessel through the range of frequencies.
(FR)Un segment d'un balai d'étanchéité (24) est monté à l'intérieur d'une cuve sous pression (10) et contre une surface courbée (44) d'un élément de manière à produire un joint entre des régions sur des côtés opposés du joint à diverses pressions. Les vibrations de la cuve sur une gamme de fréquences permettent de garantir des fréquences naturelles du balai d'étanchéité dans le cadre du chargement sous pression. En outre, l'ajustement de l'interférence entre la surface courbée et les bouts de crins peut garantir, de manière similaire, des fréquences naturelles de ladite brosse dans le cadre de divers chargements d'interférence. La cuve sous pression présente des fixations (50) servant à attacher la cuve à une table vibrante, de façon à faciliter les vibrations de la cuve sur la gamme de fréquences.
