The Mean Torque for Flywheel is defined as the average torque output given by the flywheel in a two-stroke engine system. It represents the consistent torque value that would produce the same amount of work as the actual varying torque over one complete cycle.
The calculator uses the formula:
Where:
Explanation: This formula calculates the average torque by dividing the total work done per cycle by 2π, which corresponds to the angular displacement of one complete revolution in radians.
Details: Accurate calculation of mean torque is crucial for flywheel design and engine performance analysis. It helps in determining the proper flywheel size needed to smooth out torque fluctuations and maintain consistent rotational speed in two-stroke engines.
Tips: Enter the work done per cycle for the engine in joules. The value must be positive and greater than zero for accurate calculation.
Q1: Why is 2π used in the denominator?
A: 2π represents the angular displacement in radians for one complete revolution, which is necessary to convert work (energy) to torque (force × distance).
Q2: What are typical values for work done per cycle?
A: Typical values vary significantly based on engine size and type, but generally range from a few joules for small engines to thousands of joules for large industrial engines.
Q3: How does this differ from four-stroke engine calculations?
A: While the basic principle is similar, four-stroke engines complete one power cycle every two revolutions, which may require different considerations in the calculation.
Q4: What factors affect work done per cycle?
A: Engine displacement, compression ratio, fuel type, air-fuel mixture, and combustion efficiency all significantly affect the work done per cycle.
Q5: How accurate is this calculation for real-world applications?
A: This provides a theoretical mean value. Actual torque variations may require additional analysis for precise flywheel design, considering peak torque values and fluctuation patterns.
