New computer-controlled tri-axial fatigue testing machine for precise emulation of mechanical fatigue
Hitachi, Ltd. announced the development of a new computer-controlled tri-axial material fatigue testing machine to emulate the complex stress conditions subjected during operation on mechanical structures such those in construction machinery and renewable energy facilities. When the testing machine was used to emulate the stress conditions on actual construction machinery using a test specimen, it was found that stress conditions could be emulated within an error range of less than 3%. By applying this fatigue testing machine to optimizing the design of social infrastructure products, Hitachi will be able to achieve the most appropriate structural design in line with the use conditions thus contributing to improved reliability as well as reducing material costs.
