Abstract

Regenerative vehicles are working even on less busy lines. The brake shoe will be heavily abraded. Therefore the resistor is mounted on the vehicles. It is desirable not to mount the resistor on the vehicle. Then, to mount or not should be decided with clever judgment. Therefore, we studied the effective coefficient of regenerative energy which provides the criteria for judgment. We looked for an estimation formula of effective coefficient of regenerative energy. We proposed a technique of estimating manually and by a simple program based on that formula and confirmed that the calculation can be precise enough to be practically employed. 1 Preface Recently, aged vehicles are being replaced with regenerative vehicles (vehicles that
