1. What is Bending Moment at Central Plane of Crankpin?

The bending moment at the central plane of the crankpin is the reaction induced in the central plane of the crankpin when an external force or moment is applied to the crankpin causing it to bend. This is a critical parameter in crankshaft design and analysis.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ M_b = R_{v1} \times b_1 \]

Where:

\( M_b \) — Bending Moment at central plane of crankpin (N·m)
\( R_{v1} \) — Vertical Reaction at Bearing 1 due to Radial Force (N)
\( b_1 \) — Centre Crankshaft Bearing1 Gap from CrankPinCentre (m)

Explanation: The bending moment is calculated as the product of the vertical reaction force at bearing 1 and the distance from the bearing to the crankpin center.

3. Importance of Bending Moment Calculation

Details: Accurate calculation of bending moment is crucial for crankshaft design, stress analysis, and ensuring structural integrity under maximum torque conditions. It helps in determining the appropriate dimensions and material selection for the crankshaft.

4. Using the Calculator

Tips: Enter the vertical reaction force at bearing 1 in Newtons and the distance from bearing 1 to crankpin center in meters. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why is bending moment calculation important in crankshaft design?
A: Bending moment calculation helps determine the stress distribution in the crankshaft and ensures it can withstand operational loads without failure.

Q2: What factors affect the bending moment at the crankpin?
A: The bending moment is affected by the magnitude of the radial force, the distance from the bearing to the crankpin center, and the crankshaft geometry.

Q3: How is the vertical reaction force at bearing 1 determined?
A: The vertical reaction force is typically calculated from the radial component of the thrust force acting on the connecting rod and the crankshaft's support conditions.

Q4: What units should be used for input values?
A: Force should be in Newtons (N) and distance in meters (m) for consistent results in SI units.

Q5: Can this calculator be used for other types of crankshafts?
A: This calculator is specifically designed for centre crankshafts at maximum torque conditions. Different crankshaft configurations may require different calculations.
