The Application of High Efficient Fatigue Testing Method on Engineering Machinery Steel

摘要

The fatigue performance study of high-strength engineering machinery steel is of great significance, as they often bear the reciprocating cycle load, which prone to fatigue fracture damage. Recently, the requirement of fatigue test of kinds of high grade steel is increasing rapidly. However, the existing traditional fatigue testing technology with low efficiency is relatively backward. This contradiction is increasingly outstanding. This paper presents a remote control technology and some efficient time management methods of fatigue test. The new methods are applied on high strength engineering machinery steel. Results show that these methods can effectively improve the efficiency of fatigue test.
