Destructive tensile test report

인장파괴 시험 리포트

시험조건

ㆍ가공 후 열처리
ㆍ시료 : 숄더핀
ㆍ시료는 10,000파운드(4.5톤)용
ㆍ시료 총수량 : 6개

상단의 그래프와 데이터는 1만 파운드(4.5톤) 호이스트링에 사용되는 숄더핀 6개에 대한 인장시험에 관한 자료입니다. 결과에 따르면, 숄더핀이 견딜 수 있는 평균 최대하중은 20.3톤이며, 이를 안전율로 환산하면 사용하중에 약 4.5배가 됩니다. 한 개의 호이스트링은 통상 2개의 숄더핀을 사용합니다. 현대정기의 호이스트링은 5배 이상의 안전율을 보장합니다. 인장파괴시험자료 및 성적서는 고객의 요청에 따라 제공됩니다.

상단의 그래프는 다음 3가지 중요 포인트를 말해줍니다.
1. 소재와 열처리 품질의 일관성 2. 안정적인 항복강도와 인장강도의 일관성 3.보장된 안전율

호이스트링의 인장파괴시험

ㆍ시료: CFM2061 (시용하중: 11 톤)
ㆍ최대하중 73.2 톤에서 숄더핀 1개 파단

Safety Factor(안전율)
= Max Load (최대하중) ÷ Rated Load (사용하중)
= 73,169.74 kgf ÷ 11,000 kg
= 6.65
