Development of practical small testing machine(1) - fatigue life testing machine

摘要

The fatigue test of the movement transmission member was done. 1) The life of SUS 304 wire rope is put off by the surface treatment. 2) There are no relations in the stress amplitude, and a crack causing SUS 304 endless belt from the welded section, and it is ruptured. 3) When it is compared with the steel, the fatigue limit ratio of amorphous is a low value of 0.16. 4) The fatigue limit of the Zn coating stainless steel wire rope is 200 N/mm{sup}2 with the tension 2 N, 310N mm{sup}2 with 3N.
