جدول اشتال نبشی

مقادیر موجود در این جدول به شرح زیر است:

  1. a X b X s: این مقادیر نشان‌دهنده ابعاد نبشی هستند:

    • a: طول یکی از بال‌های نبشی (در میلی‌متر)
    • b: طول بال دیگر نبشی (در میلی‌متر)
    • s: ضخامت نبشی (در میلی‌متر)
  2. mm: واحد میلی‌متر که برای مقادیر طولی مانند ابعاد بال‌ها استفاده می‌شود.

  3. r1: شعاع انحنای داخلی بین بال‌ها (در میلی‌متر).

  4. r2: شعاع انحنای بیرونی بال‌ها (در میلی‌متر).

  5. F (cm²): مساحت مقطع عرضی نبشی (در سانتی‌متر مربع).

  6. G (kg/m): وزن واحد طول نبشی (به ازای هر متر) بر حسب کیلوگرم.

  7. ex (cm): فاصله مرکز سطح مقطع از محور مختصات x.

  8. ey (cm): فاصله مرکز سطح مقطع از محور مختصات y.

  9. tan α: تانژانت زاویه α که بین بال‌ها قرار دارد.

  10. Jx (cm⁴): ممان اینرسی حول محور x (مربوط به خمیدگی حول این محور).

  11. Wx (cm³): مدول مقطع حول محور x.

  12. ix (cm): شعاع ژیراسیون حول محور x (نشان‌دهنده مقاومت به تغییر شکل حول این محور).

  13. Jy (cm⁴): ممان اینرسی حول محور y (مربوط به خمیدگی حول این محور).

  14. Wy (cm³): مدول مقطع حول محور y.

  15. iy (cm): شعاع ژیراسیون حول محور y.

  16. Jξ (cm⁴): ممان اینرسی حول محور ξ (محور اصلی مقطع).

  17. iξ (cm): شعاع ژیراسیون حول محور ξ.

  18. Jη (cm⁴): ممان اینرسی حول محور η (محور اصلی دیگر مقطع).

  19. iη (cm): شعاع ژیراسیون حول محور η.

  20. a1 (mm): مقدار فاصله از نقطه مشخصی در جدول، معمولاً برای طراحی‌های خاص محاسبه می‌شود.
