Abstract
Dynamical analysis plays a key role in development and optimalization of rail vehicles. The article deals with simulation analysis of a rail vehicle with an active tilting system of the vehicle body, design of the rail vehicle in CAD program CATIA and dynamical analysis in program SIMPACK, with the RAIL expansion. Such body mounting on vehicle bogies is significantly more complicated than the design of conventional rail vehicles. The purpose of this type of body mounting is to increase the size of body tilt during ride in a curve and thus reduce the lateral unbalanced acceleration affecting the passengers, or allow higher driving speed in a curve with the same radius while keeping the lateral acceleration value respectively. Eight variants of different velocity, vehicle occupancy and setting of the tilting mechanism were analyzed. We determined the average value of passenger comfort from the simulation results. We have determined the value of passenger comfort during the ride in a curve from the simulation results.
Highlights
Dynamical analysis plays a key role in development and optimalization of railway rolling stock [1,2,3,4,5,6]
We focused on simulation of a rail vehicle with a car body tilting mechanism
The vehicle model was created in program CATIA, the basic parameters were set and the model was imported to SIMPACK
Summary
Dynamical analysis plays a key role in development and optimalization of railway rolling stock [1,2,3,4,5,6]. Simulation programs make it possible to perform analysis in different ways and help to optimize the financial and time requirements in comparison with testing of a rail vehicle using measuring device in real conditions [7, 8]. In the paper we focused on the ride comfort of passengers in a rail vehicle with a tilting bogie riding along a defined track in relation to STN EN 12299:2009 standard.
