Introduction to Vehicle Track Coupled Dynamics

Vehicle Track Coupled Dynamics (VTC Dynamics) is an analytical framework and simulation methodology focused on the interaction between rail vehicles and track structures. The core of VTC Dynamics is the modeling of both vehicle dynamics and track response under dynamic loads, which is crucial for assessing the performance, safety, and comfort of rail systems. The theory considers various factors such as vehicle speed, track irregularities, vehicle suspension systems, and track stiffness. An example illustrating its application is the simulation of train passage over different track conditions to predict potential track damages and ride quality issues. Powered by ChatGPT-4o
