Development and Several Additional Performances of Dual-Spindle Rotating Bending Fatigue Testing Machine GIGA QUAD

摘要

In order to nvestigate the fatigue characteristics,of metallic materials experimentally,a long period of time is required to get sufficient number of S-N data.In recent years,in order to overcome this difficulty,multi-type rotating bending fatigue testing machine whose name is GIGA QUAD have been developed by Yamamoto Metal Technos Co.,Ltd.,in which four specimens can be tested simultaneously.In this time,some additional new functions have been developed as follows;(1) 'high and low temperature environmental testing unit' whose target temperature is in a range of 600°C and -150deg.C,(2) 'constant temperature/humid environmental testing unit' combined with the conventional corrosive cell,(3) 'fracture alarm unit'.and (4) '2-step variable loading unit'.By combining these new functions with the machine of GIGA QUAD,one can perform the fatigue tests efficiently corresponding to the respective requirements for researchers in both of academic and industrial sectors.
