A Study on the Wheelset / Slab Track Vertical Interaction
This paper deals with the interaction between a moving wheelset and a slab track due to the shortpitch corrugated rail. The wheelset is modeled using a free-free Timoshenko beam with attached rigid bodies as the axle boxes, wheels and brake discs. The slab track model consists of elastically supported double EulerBernoulli beams. In fact, both wheelset and slab track are symmetric structures an...
متن کاملDynamic Response of the Coupled Vehicle-Floating Slab Track System using Finite Element Method
In present study, a mathematical model of the vehicle–floating slab track (FST) interaction is established to investigate the coupled behaviour of vehicle–track system. The FST is modelled as the double Euler -Bernoulli beam including the rail and slab. The railway vehicle is simplified as a multi-rigid-body model. The wheel–rail interface is treated using a nonlinear Hertzian contact model, co...
متن کاملDesign and simulation of a pressure sensor based on a two dimensional photonic crystal slab of PbMoO4
In this paper the design and three dimensions (3D) simulation of a photonic crystal (PC) pressure sensor is presented. The device is based on a 2D PC slab of PbMoO4. The simulations are based on finite element method (FEM) and finite-difference time-domain (FDTD) method and are done using CST STUDIO SUITE software. The sensitivity of the proposed sensor is calculated by considering the deformat...
متن کاملA Simpler and Faster Version of Two-Dimensional Gel Electrophoresis Using Vertical, Mini SDS-PAGE Apparatus
We have modified one of the most useful methods of protein separation; namely, two dimensional gel electrophoresis (2-DE). This modified version of 2-DE is not only simpler and easier but also faster than all the currently available methods. In this method, isoelectric focusing is carried out in the first dimension using a vertical sodium dodecyl sulfate polyacrylamide gel electrop...
متن کاملAcceleration-Based Quality Assessment of Railway Tracks using a 2D simulation model and recorded track data
Car body acceleration is an important factor affecting track safety and ride comfort, which are two primary aspects of railway systems. Though track level is an important source of wagon body acceleration, no quantitative relation between them is available and the aim of this paper is to propose a method to address this issue. To do so, car body acceleration is determined using a 10 DOF simulat...
