The prediction technology study of fatigue life for key parts of a tracked vehicle's suspension system
In allusion to fatigue life of a tracked vehicle torsion bar, a virtual prototype model of the tracked vehicle suspension system including a flexible torsion bar was built based on dynamic simulation software-ADAMS.
The finite element analysis of the vehicle frame was made and the result satisfied the requirements.
These methods may prove to be especially efficient for testing metallurgical flaws in wheel pairs of rolling stock, workpieces for turbine rotors, and similar items.
The ultrasonic system designed for performing acceptance tests of wheelset axles of railway rolling stock during production with the aim of detecting metallurgical flaws and/or flaws caused by drawbacks in the manufacturing process is substantiated.
DGS diagrams used for tuning the sensitivity of the echo-pulse method of ultrasonic testing of railway rolling stock's wheel-pai
Special features of DGS-diagram-based sensitivity tuning of the ultrasonic testing of railway rolling stock's wheel-pair axles through the use of normal and angle probes from the end and lateral surfaces are considered.
