| Sumario: | [EN] This End-of-Master’s project focuses on the validation of a railway dynamics calculation tool which will be referred hereafter as Proposed Model CIIM (Mechanical Engineering Research Centre) and developed by an research groupt. To that purpose, various simulations of the vehicle’s circulation in curves will be carried out, taking into consideration different speeds, camber curves and radious of curvature. To that end, there will be some explanations on certain theoretical antecedents that will help us to a better and global understanding. Some of the dynamic problems in terms of vehicle-railway intercation will be tackled, giving an overall view of the main problems within railway dynamics in the domain of low frenquencies when the vehicles negotiates a curve. We will explain the railway-vehicle interaction model on a flexible axe developed by a research group, where we will briefly summarize the modelling of the railway axle, the suspended massses and the railway itself. Regarding the validaton of the Proposed Model, we will be using a commercial program on railway dynamics called Adams Rail. Various curve scenarios and different speeds will be simulated taking into consideration different camber curves and radius of curvature along which a model tren vehicle 1 (agreed at Manchester Benchmarks) will run. The same simulations will be carried out using the Proposed Model and the results will be compared using Matlab software. Later on, a conclusions section will be included so as to give further detail of the most relevant contributions of the study and to determine the model’s validation itself. The idea of developing the Proposed Model CIIM arises mainly with the purpose of getting an integral model of the vehicle’s behaviour both at low and high frequencies aiming at dealing with some railway problems in curves, such as tread noises, rail squeals and corrugation. |
