Nowadays, the weight minimization of a structure without affecting initial performance is challenging issue for design engineers. Weight reduction approaches such as topological optimization provide solution to determining optimal shape compromising intended and required functionality. For most structures, topology problems have been formulated either minimize compliance or under volume stress ...

The mechatronic vehicle developed within the Shift2Rail projects Run2Rail, Pivot, NEXTGEAR, and Pivot2 is evaluated with respect to wheel wear. KTH wear model used determine coefficients of Archard’s map reproduce measured worn profiles present running on Metro Madrid line 10. same then evaluate performance controlled two variants a feedforward controller. first one uses on-board measurements, ...

This paper deals with the lateral force effects of conventional four-axle railway vehicles in conditions S-shape curves, which are represented especially by switches negotiated diverging direction. With use a multi-body model an electric locomotive, sensitivity analysis selected vehicle parameters on maximum guiding S-curve is performed. Subsequently, definition so-called equivalent proposed. s...

This paper presents an active steering system designed to ensure both the curving performance and running stability of a vehicle. Electro-hydraulic actuators installed in place anti-yaw dampers generate yaw moment between carbody bogie. The detects curves with gyroscopes mounted on configuration enables reduction wheel/rail lateral force without requiring complicated mechanical links bogies. al...

This paper analyses the dynamic behavior of a rail vehicle using experimental and simulation analysis on multi-rigid–flex body model. The mathematical models are developed considering car body, bogie frame, wheel axle for vehicles rigid–flexible multi-rigid formulations, taking as rigid flexible flex–rigid analysis. A finite element model was in ANSYS, substructure modal were performed. is vali...

The aim of this work is to develop a model-based methodology for monitoring lateral track irregularities based on the use inertial sensors mounted an in-service train. To end, gyroscope used measure wheelset yaw angular velocity and two accelerometers are acceleration bogie frame. main contribution present development very efficient Kalman-based strategy estimate irregularities. Kalman filter h...
