…Typical fatigue testing machines include tension-compression, repeated bending, and repeated torsion testing machines, and the repeated load is applied using a crank mechanism, electromagnet, or hydraulic device. A simple fatigue testing machine is the rotating bending fatigue testing machine, in which the test piece rotates while being subjected to a bending moment. Impact testing machines are usually designed to perform impact bending and impact tensile tests, but impact bending is more commonly performed. … *Some of the terms used in the "rotating bending fatigue testing machine" are listed below.

…疲れ試験機には代表的なものとして,引張圧縮,繰返し曲げ,繰返しねじりなどの試験機があり,繰返し荷重はクランク機構,電磁石,油圧装置などで加えられる。簡便な疲れ試験機として回転曲げ疲れ試験機があるが,この場合には,試験片は曲げモーメントを受けながら回転するようになっている。衝撃試験機は,ふつう,衝撃曲げおよび衝撃引張りの試験が行えるように作られているが,衝撃曲げのほうが多く行われる。… ※「回転曲げ疲れ試験機」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
