Introduksiyon
Say pan-break load na steel wire rope et sakey ed saray sankaimportantian ya parametro ed rigging engineering. No natalosan no panon ya suston kalkulaen itan, naseguro so ligtas ya operasyon na panag-alsa tan panumbok ed saray estandarte na industriya a singa say ISO 2408 tan EN 12385.
Anto so Breaking Load?
Say breaking load, ya tatawagen met ya minimum breaking force (MBF), et say sankatageyan ya puersa ya nasarag na wire rope antis ya naderal. Kaslakan ya ibalikas itan ed kilonewtons (kN) odino tonelada (t).
Saray Manunan Bengatla ya Makaapekto ed Breaking Load
- Say biskeg na panag-awit na alambre:Kaslakan et manlapud 1570 N/mm2 anggad 2160 N/mm2.
- Panagpaalagey na Lubir:Say bilang na saray higos, saray alambre ed kada higos, tan say klase na core et mangaapekta ed biskeg na panag-break.
- Fill Factor:Say ratio na metal ya cross-sectional area ed circumscribed area na lubir.
- Spinning Loss Factor:Saya so sengegan na ibawas na biskeg lapud helical winding na saray alambre.
Pormula na Pan-breaking Load
Say teoretikal ya breaking load F et nayarin kalkulaen ed:
F = K × d² × R₀ / 1000
Iner:
- F= Minimum breaking load (kN)
- K= Empirical factor depende ed ginawa na lubir (kaslakan et 0.3-0.55)
- d= Nominal ya diametro na lubir (mm)
- R₀= Nominal ya biskeg na saray alambre (N/mm2)
Praktikal ya Alimbawa
Parad 20mm diameter 6×36WS-IWRC steel wire rope ya walay 1960 N/mm2 ya grado:
F=0.40 × 202 × 1960 / 1000=313.6 kN (manga 32 tonelada)
Saray Konsideraen ed Kaligenan
Lanang ya mangiyaplika na safety factor (kaslakan et 5:1 parad pangkabilugan ya panag-alsa, anggad 10:1 parad panag-alsa na totoo) no determinaen so working load limit (WLL).
Konklusyon
Say suston panagkuenta na breaking load et manunan paraan pian maligen so panag-rigging. Lanang ya imanoen iray detalye na manggagawa tan saray matukoy ya estandarte no determinaen so kapasidad na lubir.
