Dynamic Train/Track Interaction Including State-Dependent Track Properties and Flexible Vehicle Components

摘要

An existing state-space based numerical method (see Reference [1]) to simulate verti- cal dynamic interaction between a rolling train and a railway track has been improved and extended. The modified method allows for non-linear track model properties and flexible vehicle model components. Track model properties are separated into lin- ear contributions corresponding to a non-loaded track configuration and increments which are state-dependent.
