With the computer simulation method, we can e asily calculate the spatial vibration responses, such as the vibration displacem ent and acceleration of the bridge and the rolling stock of both the speed-incr ease train and the deck steel plate girder bridge with or without various reinfo rcing measures.
The paper introduces sampling method of evaluating safety and riding comfort of rolling stock when high-speed train passes a bridge, together with standards of safety evaluation. Value selecting of wheel load reduction rate in simulation calculation is explained, and parameters of safety evaluation of high-speed car dynamics test across the world has been summarized.

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.
