Description
上記の目的を達成するための本発明の請求項１によるアルミニウム合金製自動車フレーム用軸圧縮エネルギー吸収部材は、調質された熱処理型アルミニウム合金中空形材からなり、該中空形材の外殻部の形状は断面正方形または長方形で、中空部を含む全断面積は３０００〜８０００ｍｍ２のものであり、中空形材の断面には、それぞれ１０００〜４０００ｍｍ２の断面積を有しリブで区画された中空部が２つ設けられており、中空形材における各辺の平均肉厚をｔ（ｍｍ）、中空形材の外郭部とリブとの結合部のコーナー部の半径をＲ（ｍｍ）としたとき、３．２ｍｍ≧ｔ≧１．５ｍｍ、３．５≧Ｒ／ｔ≧１．５の関係を満足することを特徴とする。 In order to achieve the above object, an axial compression energy absorbing member for an aluminum alloy automobile frame according to claim 1 of the present invention comprises a tempered heat-treated aluminum alloy hollow shape member, and an outer shell portion of the hollow shape member. the shape in cross-section square or rectangular, the entire cross-sectional area including the hollow portion is of 3000～8000Mm 2, the cross section of the hollow profile is partitioned by the respective ribs have a cross-sectional area of 1000～4000Mm 2 Two hollow portions are provided , the average thickness of each side of the hollow shape member is t (mm), and the radius of the corner portion of the joint portion between the outer portion of the hollow shape member and the rib is R (mm). In this case, the relationship of 3.2 mm ≧ t ≧ 1.5 mm and 3.5 ≧ R / t ≧ 1.5 is satisfied.
図１１に示すように、中空形材１は、リブ２で区画された２つの中空部３、３を有する外殻の断面形状が正方形または長方形のもので、中空形材１の中空部を含む全断面積は３０００〜８０００ｍｍ２、中空部３、３の断面積はそれぞれ１０００〜４０００ｍｍ２であり、中空形材１の各辺の平均肉厚をｔ（ｍｍ）、外殻部４とリブ２との結合部５のコーナー部の半径をＲ（ｍｍ）としたとき、３．２ｍｍ≧ｔ≧１．５ｍｍ、３．５≧Ｒ／ｔ≧１．５の関係を満足するよう設計される。 As shown in FIG. 11, the hollow shape member 1 includes a hollow portion of the hollow shape member 1 having a square or rectangular cross-sectional shape of an outer shell having two hollow portions 3 and 3 partitioned by ribs 2. The total cross-sectional area is 3000 to 8000 mm 2 , the cross-sectional areas of the hollow portions 3 and 3 are 1000 to 4000 mm 2 , the average thickness of each side of the hollow profile 1 is t (mm), the outer shell portion 4 and the rib 2 When the radius of the corner portion of the connecting portion 5 is R (mm), it is designed to satisfy the relationship of 3.2 mm ≧ t ≧ 1.5 mm and 3.5 ≧ R / t ≧ 1.5.
