Simulations and calculations
HBM's nCode software branch itself began in the rail industry in the 1980s, so it is no surprise many companies in the design and operation of trains continue to derive benefits from the latest generation of nCode products.
Upfront design of train structures and bogies can be optimized for fatigue performance, thus saving weight and reducing energy required and damage to tracks. Operational measurements of strain and acceleration are taken on both train structures and tracks to predict failure and also assess damage. In this way, problems can be identified before they can cause failure and thus preventing serious derailments and accidents.
Typical applications and measurements are:
- Understand fatigue of railway components like wheels, bogies, axles, etc.
- Understand field loading – how often are bumps seen, how many starts/stops per hour or mile, etc.
- Fatigue analysis of structural members
- Ride quality analysis to understand the impact of ride and track harshness on the riders
- Remote monitoring of tracks
