Perçinli birikmanin nosozlik rejimlari qanday?

Uchta asosiy nosozlik rejimi mavjud: (1) Perçinning kesilishi — perçinlar ko'ndalang kesim bo'ylab kesma kuchdan ishdan chiqadi, (2) Ezilish nosozligi — perçin plita materialiga botib kiradi, (3) Plitaning yirtilib chiqishi — plita perçin teshiklari o'rtasida yoki chetidan yirtiladi.

Perçinning kesish mustahkamligi qanday hisoblanadi?

Rivet shear capacity = n × (π/4) × d² × τ_allow, where n is number of rivets, d is rivet diameter, and τ_allow is allowable shear stress of the rivet material (typically 0.6 × tensile strength).

Perçinli birikmalardagi ezilish nosozligi nima?

Bearing failure occurs when the rivet crushes into the plate material. Bearing capacity = n × d × t × σ_bearing, where t is the thinner plate thickness and σ_bearing is the allowable bearing stress (typically 1.5–2.0 × tensile strength).

Plitaning yirtilib chiqish mustahkamligini qanday hisoblash mumkin?

Tear-out (net section failure): P_tear = (w - n_row × d) × t × σ_tensile, where w is plate width, n_row is number of rivets in the critical row, d is hole diameter, and t is plate thickness.

Perçinli birikmanin samaradorligi nima?

Birikma samaradorligi = minimum(siljish quvvati, tayanch quvvati, yirtilish quvvati) / (teshiksiz plastina mustahkamligi). Odatda samaradorlik naqshga qarab 50% dan 85% gacha bo'ladi.
