| Abstract: | Fractured piston rod and connecting rod in a methane refrigerant compressor was analyzed by chemical analysis, mechanical testing, metallographic and fractographic examination. Stress analysis and fatigue strength calculation were also carried out. It was concluded that connecting and piston rod fracture were results of fatigue fracture, and main causes of fracture were identified. Prevention measures were also proposed to avoid further similar accident. |
