Resistance due to Starting for Train Vehicle is the resistance generated due to train vehicle at the starting. It represents the additional force required to overcome inertia when initiating movement from a stationary position.
The calculator uses the formula:
Where:
Explanation: The formula calculates the starting resistance as 0.5% of the total train weight, accounting for the initial force required to overcome static friction and inertia.
Details: Accurate calculation of starting resistance is crucial for determining the required tractive effort, designing locomotive power systems, and ensuring efficient train operation during startup conditions.
Tips: Enter the weight of the train in tonnes. The value must be valid (weight > 0). The calculator will compute the resistance due to starting based on the standard coefficient of 0.005.
Q1: Why is the coefficient 0.005 used in the formula?
A: The coefficient 0.005 represents 0.5% of the train's weight, which is an empirical value established through railway engineering studies for calculating starting resistance.
Q2: Does this resistance apply throughout the journey?
A: No, starting resistance is specific to the initial movement from rest. Once the train is moving, different resistance factors come into play.
Q3: How does train weight affect starting resistance?
A: Starting resistance increases linearly with train weight, as heavier trains require more force to overcome inertia and static friction.
Q4: Are there other factors that affect starting resistance?
A: While weight is the primary factor, track conditions, temperature, and mechanical factors can also influence actual starting resistance.
Q5: Is this formula applicable to all types of trains?
A: The formula provides a general estimation for standard railway vehicles. Specialized trains or unusual conditions may require additional considerations.
