Future applications

Large scale structural testing with four parallel actuators in force and displacement control, including data acquisition and results processing capabilities.

Challenge

Alstom are investigating the design, construction and manufacture of the floor panel assembly during production and product lifecycle, with a specific focus on joint configurations and anti-vibration to reduce noise levels.

 

Solution

The UTS Tech Lab team will investigate and validate the design, assembly and lifetime durability of a new commuter rail carbody floor panel through a series of structural tests.

The large-scale panels will be fatigue tested using four parallel actuators in force and displacement control in a temperature and humidity controlled environment. The load, displacement and pressure data will be acquired and processed using a bespoke software tool.

The new floor will offer improved performance in terms of noise, vibration and harshness (NVH) to enhance passenger comfort and durability for extended life. This new solution will be deployed in Perth’s new C-series trains in 2022.
