Simulation analysis of ultrasonic inspection of hollow axle with different segments
2015 International Conference on Control, Automation and Robotics, 2015Hollow axle has replaced the traditional solid axle in high-speed trains due to the increased operational speed. The ultrasonic inspection on hollow axles must be conducted to ensure the safe operation of high-speed trains. The hollow axle can be artificially divided into different segment based on the shape and size of different axle segments ...

The influence of coupling layer thickness on hollow axles ultrasonic testing
2015 International Conference on Control, Automation and Robotics, 2015The thickness of coupling layer between the hollow axle inner wall and the probe wedge may vary during actual ultrasonic inspection. To study the influence of coupling layer thickness on the hollow ultrasonic inspection, the simulation models with different probe angles and different thicknesses of coupling layer were established with COMSOL ...

Numerical Simulation for Thick-Walled Hollow Axle during Cross Wedge Rolling
Advanced Materials Research, 2011The paper investigates a process of cross wedged rolling (CWR) for manufacturing thick-walled hollow axles. A finite element numerical model coupled deformation and heat transfer of CWR is established using commercial finite element software DEFORM-3D. The rolling process of hollow axle during CWR is simulated successfully.

Cylindrical Guided Wave Approach for Damage Detection in Hollow Train Axles
Structural Health Monitoring 2015, 2015Guided-waves are among the most commonly used techniques for Structural Health Monitoring. However, due to the high thickness-to-wavelength ratio, ultrasonic waves propagating in thick-walled cylindrical structures, such as train bogie axles, exhibit very complex multimodal behavior, thus creating additional challenges to conventional damage detection ...
