Description:
As part of Transport for NSW’s project to reduce rail squeal generated through the wheel-rail interface, EngAnalysis was involved in the measurement and analysis of rail bogie warp stiffness. This included static testing of the warp stiffness of bogies, trials to modify the warp stiffness through component changes, and on-track testing to verify changes.
EngAnalysis developed analysis and reporting software to provide the test results and statistics from the data gathered on the bogie warp testing rig and undertook a statistical review of static testing and dynamic on track test results linking angle of attack, bogie warp, warp stiffness and noise.
