1. What is Bending Stress in Crankweb Due to Radial Force?

Bending Stress in Crankweb Due to Radial Force is the bending stress in the crankweb due to the radial component of force on connecting rod at crank pin. It's a critical parameter in crankshaft design and analysis.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \sigma_r = \frac{6 \times M_{br}}{t^2 \times w} \]

Where:

\( \sigma_r \) — Bending Stress in Crankweb Due to Radial Force (Pa)
\( M_{br} \) — Bending Moment in Crankweb Due to Radial Force (N·m)
\( t \) — Thickness of Crank Web (m)
\( w \) — Width of Crank Web (m)

Explanation: This formula calculates the bending stress in the crankweb based on the applied bending moment and the geometric properties of the crank web.

3. Importance of Bending Stress Calculation

Details: Accurate calculation of bending stress is crucial for ensuring the structural integrity and reliability of crankshafts in internal combustion engines. It helps prevent fatigue failure and ensures optimal performance.

4. Using the Calculator

Tips: Enter bending moment in N·m, thickness and width in meters. All values must be positive and non-zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What units should be used for input values?
A: Bending moment should be in Newton-meters (N·m), and both thickness and width should be in meters (m).

Q2: What is the typical range of bending stress values?
A: Bending stress values vary depending on engine size and design, but typically range from several MPa to tens of MPa.

Q3: How does this relate to overall crankshaft design?
A: This calculation is one component of comprehensive crankshaft stress analysis, which also includes torsional stress, shear stress, and fatigue analysis.

Q4: Are there safety factors to consider?
A: Yes, engineering designs typically include safety factors to account for material variations, manufacturing tolerances, and unexpected loading conditions.

Q5: Can this calculator be used for other types of crankshafts?
A: While specifically designed for center crankshafts, the fundamental principles apply to various crankshaft configurations, though specific design considerations may vary.
