AN INTEGRATED DYNAMIC SIMULATION OF METRO VEHICLES IN A REAL OPERATING ENVIRONMENT
Vehicle System Dynamics, 1994SUMMARY An integrated computer design method has been developed for fatigue life prediction of railway vehicle bogies. In principle, there are five parts in the procedure: specification and measurement of track geometry data; assembly of a suitable vehicle computer model and specification of rail/wheel profiles; description of dynamic suspension load ...

Soft Failure Analysis of Metro Vehicle Charger Circuit
Applied Mechanics and Materials, 2013Failure prediction is of great significance for power electronics systems. Taking the metro vehicle charger circuit as an example, soft failures are discussed. The paper established the system simulation model through MATLAB/SIMULINK, and carried on spectrum analysis with POWERGUI module, and analyzed system output when the parameter changed.

Understanding high coupler forces at metro vehicles
Vehicle System Dynamics, 2007Couplers of motor units connect the wagons mechanically, electrically and pneumatically. Nowadays they are also designed to meet crash requirements. Since the traction and braking forces are distributed along the motor unit, coupler forces occuring during operation are considered to be low. In most cases, this is actually true.

Reliability Analysis and Prediction of Metro Vehicles’ Bogie Frame
Applied Mechanics and Materials, 2014Frame is the main bearing component of bogie and the reliability of which directly affects the performance and safety of the locomotive. Survival analysis is used for reliability analysis of bogie frame to solve uncertain life time problem. It turns out that the best life distribution model is three-parameter Weibull distribution. A prediction model of

Out-of-Round Wheels and the Correlation Problem of Metro Vehicles
International Conference on Transportation Engineering 2007, 2007Spalling like scales of fish will emerge on the connection area between wheel tread and flange of one metro vehicle after it running a period of time on the track. The method of polish the track has not solved the phenomena yet. When wheel is out-of-round, the vertical vibration of the car-body is very big, and the tread must be cut to eliminate the ...
