Title (EN) HOLLOW STABILIZER AND MANUFACTURING METHOD THEREFOR
(FR) STABILISATEUR CREUX ET SON PROCÉDÉ DE FABRICATION
(JA) 中空スタビライザー及びその製造方法
Abstract:
(EN) The present invention comprises: a step for providing a tubular member (10) for use in a hollow stabilizer; and a step for polishing the inner surface of the tube by causing a viscoelastic polishing medium (200) to flow inside the tube between a first end (11) and a second end (12) of the tubular member (10). The tubular member (10) may be bent into a predetermined shape or may be heat treated. The polishing medium (200) may include a viscoelastic base material, and a particulate abrasive. The inner surface of the hollow stabilizer is uniformly polished to reduce the surface roughness of the inner surface of the tube and/or impart compressive residual stress, thereby improving the fatigue life.
(FR) La présente invention comprend : une étape consistant à fournir un élément tubulaire (10) destiné à être utilisé dans un stabilisateur creux ; et une étape consistant à polir la surface interne du tube en amenant un milieu de polissage viscoélastique (200) à s'écouler à l'intérieur du tube entre une première extrémité (11) et une seconde extrémité (12) de l'élément tubulaire (10). L'élément tubulaire (10) peut être coudé de sorte à obtenir une forme prédéfinie ou être traité thermiquement. Le milieu de polissage (200) peut comprendre un matériau de base viscoélastique, et un abrasif particulaire. La surface interne du stabilisateur creux est polie uniformément pour réduire la rugosité de surface de la surface interne du tube et/ou conférer une contrainte résiduelle de compression, ce qui permet d'améliorer la durée de vie en fatigue.
(JA) 中空スタビライザーに用いる管状部材(10)を提供する工程と、管状部材(10)の第1端(11)と第2端(12)との間で管内に粘弾性を有する研磨メディア(200)を流して管の内面を研磨する工程とを含み、管状部材(10)は、所定の形状に曲げ加工されていてもよく、熱処理されていてもよく、研磨メディア(200)は、粘弾性を有する母材と、粒子状の研磨剤とを含むものであってよく、中空スタビライザーの内面を均一に研磨して、管の内面の表面粗さを低減し、及び/又は、圧縮残留応力を付与することにより疲労寿命を向上させる。
