Dynamic behavior of guideway switch beams

WebThe guideway is assumed to be made up of identical simply supported beams with single spans and rigid supports. The vehicle is considered to a two-dimensional vehicle model with primary and secondary suspensions. Three kinds of loading modes acting at each beam of guideway are first developed according to the locations of suspensions of vehicle. WebThe computation of dynamic response for the train-guideway system was carried out using an iterative approach with Newmark's method. The vibration behavior of the dynamic responses of train traversing the guideways is studied herein based on the numerical results and the experimental data. The resonant conditions of single-span guideway are ...
