Fault Tolerant Strategy for Actively Controlled Railway Wheelset
this paper studies the key issue of fault tolerance for actively controlled railway wheelsets. It assesses failure modes in such systems, with a focus on actuator failures, and consequence of those hardware failures. It seeks to establish the necessary basis for control reconfiguration to ensure system stability and performance in the event of a faulty, without the need for hardware redundancie...
متن کاملRailway Wheelset Parameter Estimation Using Signals from Lateral Velocity Sensor
A type of parameter estimation technique based on the linear integral filter (LIF) method, the least-absolute error with variable forgetting factor (LAE+VFF) estimation method, is proposed in this paper to estimate the railway wheelset parameters modelled as a time-varying continuous-time (C-T) system. The inputs to the parameter estimator are the control signal and the railway wheelset system ...
متن کاملSEISMIC RELIABILITY ASSESSMENT OF OPTIMALLY DESIGNED STEEL CONCENTIRCALLY BRACED FRAMES
The main aim of this study, is to evaluate the seismic reliability of steel concentrically braced frame (SCBF) structures optimally designed in the context of performance-based design. The Monte Carlo simulation (MCS) method and neural network (NN) techniques were utilized to conduct the reliability analysis of the optimally designed SCBFs. Multi-layer perceptron (MLP) trained by back propagati...
متن کاملCalculation of lateral velocity estimation and error discrimination for railway wheelset to avoid sliding
Lateral velocity has very backbone position in the railway vehicle wheelset dynamics as it usually becomes cause of derailment by sliding due to insufficient adhesion ratio. This impropriate balance is pretext owing to contamination and weather procures the disturbances. This perturbation makes hindrances in proper running of wheelset on track. To analyze the noise, Kalman filter is used based ...
متن کاملNew Designs for Submillimetric Press-Fitting
Press-fitting is a very common assembly process used in many fields, especially in the watchmaking industry. It consists of introducing a shaft in a hole (also called receptor) with a certain value of tightening (or interference). However, this process is not straightforward and it is often observed that some assemblies do not manage to hold out the time and function they are meant to. In order...
