크랭크샤프트 벤딩 피로강도의 리그시험과 대상시험 상사법 개발

The objective of this research is to correlate the test condition between rig test and bench test. To correlate test condition, fatigue life test and stress measurement used in resonant fatigue machine has been conducted for 1bay crankshaft sample. Principal stress was also measured in the front side #1 cylinder pin filet of bench engine crankshaft with triaxil strain gauge. The result shows that fatigue limit of rig test and equivalent to gas pressure of bench test. This result can increase test duration efficiency and quantitative assessment of crankshaft fatigue strength.
