Sharp Curve Negotiation Analysis of Tramcar Vehicles with Different Bogie Architectures

摘要

Bogie architecture (solid axles or independently rotating wheels, monobloc or resilient wheels) has a fundamental impact on the contact forces exchanged at wheel-rail interface, especially when considering small radius curves, which are typical of urban tramways. The paper investigates how the contact forces change depending on the adopted bogie architecture, by means of multibody simulation of tramcar behaviour during curve negotiation.
