STABILISING BACK-UP SYSTEM FOR INCREASING THE SPEED LIMIT OF RAIL VEHICLES

STABILISIERENDES HILFSSYSTEM ZUR ERHOEHUNG DER GRENZGESCHWINDIGKEIT VON SCHIENENFAHRZEUGEN

To increase the speed limit of rail/wheel system vehicles, wheelsets are tracked in fixed position, shock-absorbers are introduced between the wheelsets and the bogie, the wheel section is modified, etc. The article is a theoretical examination of a passive, stabilizing back-up system with which the speed limit of a wheelset can be increased by over 100%. This back-up system consists of a ring-shaped device sliding freely on the wheelset but connected to it by springs and shock-absorbers. The authors propose three alternative types of stabiliser involving a ring-shaped weight guided by a platespring or a roller oscillator or a spring oscillator where stiffness is controlled by electromagnets. If the frequencies of the oscillator and of the wheelset crosswise movement are harmonised, the wheelset movment is stabilized up to very high-speeds.
