IMPROVEMENTS IN RAIL VEHICLE DYNAMIC PERFORMANCE THROUGH CONTROL OF LINEAR MOTOR LATERAL AND NORMAL FORCES
The objective of this research is to examine the use of linear motors for improving the lateral dynamic performance of railroad vehicles. The potential for improved vehicle stability, ride quality, traction capability, curving performance, track loading, and derailment safety results from the use of controllable lateral and normal magnetic forces present in the motor in addition to those used for propulsion. In this study recent advances in technology originally for high-speed levitated vehicles are applied to conventional railroad vehicles resulting in a system which has a higher potential for near-term implementation. The approach used combines theoretical models for the performance of rail vehicles and linear motors with model validation and concept demonstration using experimental scale models of LIMs and microprocessor control of analog simulations.
