Optimum Reduction Gear Ratio for a Rapid Transit Car in Seoul

An optimim reduction gear ratio problem for a subway rapid transit car in Seoul was solved by using a computer program package, which is a modified and extened version of the simple model by Mischke. The optimum value of reduction gear ratio was evaluated by minimizing the total start-to stop time.The validity of the computer program package was verified by cross-checking the calculated values of gear ratio and dynamic characteristics with the actual and measured values.
