Basics of PBS Analysis in Universal Mechanism software

Presentation is devoted to using Universal Mechanism software for PBS analysis of road trains.

Simulation of Road Vehicle Dynamics Using Universal Mechanism Software

Computer simulation of train-track-bridge interaction

The aim of the paper is to present the approach for simulation of dynamics of the systems consisting of railway vehicle, flexible track and flexible foundation.

Railway vehicles are considered as multibody systems that include rigid or flexible bodies, joints and force elements. The track model is considered as a periodic 3D structure consisting of rails, pads and sleepers on a flexible foundation. Two rails modelled as Timoshenko beams are discretely supported on the sleepers through the railpads and fasteners, that are modelled as nonlinear force elements. The foundation (bridge, tunnel, overpass) is considered as a flexible multibody system simulated using finite element method.

Vertical response of the track model is verified through comparison with experimental data. Test case of simulation of suburban 6-car train on a flexible railway track and three sections of U-like flexible railway bridge of 30 m each is shown. Comparison of the simulation results with experimental data is given.

Simulation of Railway Vehicle Dynamics Using Universal Mechanism Software

New! Conventional railway models, models with flexible car bodies and bogie frames, wheel-to-rail contact models, flexible track models, vehicle-track-bridge interaction, rolling contact fatigue, wheel and rail profile wear, stability and safety of railway vehicles: listed above and other questions are considered.

Railway vehicle and bridge interaction: some approaches and applications

Presented approach is based on method of dynamic simulation of flexible bodies which is implemented in UM software.

Simulation of flexible rail track dynamics

The approach to simulation of flexible railway track dynamics in Universal Mechanism software is considered. The approach supposes considering rails as Timoshenko beams and slippers as rigid bodies or Euler-Bernoulli beams.

Real-time model for simulation of tracked vehicles

A massless track-wheel-terrain interaction model for the real-time simulation of tracked vehicles is suggested. The model is oriented for simulation of tracked vehicles on highly non-smooth urban and industrial terrains that include such elements like stairs, vertical obstacles etc.

Simulation of drillstring dynamics

The various issues of simulation of drillstring dynamics using the multibody approach are considered. Different multibody models of the whole drillstring and the bottom hole assembly are discussed. Comparison of the numerical simulation, theoretical and experimental results is presented.

Simulation of Derailments

Presentation is devoted to simulation of train derailment processes and the identification of causes of derailments by using Universal mechanism software.

Three-Piece Bogie Models

Presentation is devoted to models of freight cars based on three-piece bogies and its applications.

UM RCF Presentation

Alexander Olshevskiy, Chang-Wan Kim, Hyun-Ik Yang & Alexey Olshevskiy. Wear simulation for the centre plate arrangement of a freight car

Vehicle System Dynamics: International Journal of Vehicle Mechanics and Mobility. DOI: 10.1080/00423114.2015.1023319

The bodies of many railway freight cars in many countries of the world are coupled to the running gear by means of a body centre plate that makes a friction pair with a centre bowl. During motion, the bogie is rotated and moved with respect to the car body. This leads to wear on the contact surfaces. Lubrication is inexpedient in this case because the friction forces damp the vibrations (so-called bogie hunting) during motion. Usually, centre plates exhibit noticeable wear after two years of operation. Reducing wear requires knowing details of the wear process which, in turn, requires computer simulation of freight car motion for an operation period of 10–15 years. The purpose of this paper is to develop a universal method for wear simulation of friction pairs that could be used, in particular, for the centre plate of a freight car.
