ORE TRAIN DUMPER OPERATION Overview - PROCESS Instrumented wagons and computer simulation are used to: establish current coupler load spectra from field data; evaluate alternative indexing profiles; and validate the optimum indexing profiles once implemented. Field data is used to ensure accurate simulation results and the simulations reduce the number of field tests required.
Universal Mechanism Overview - Institute of Railway Technology is the official representative of Universal Mechanism in Australia and provides services related to this software package.
UNIVERSAL MECHANISM - Simulation of railway vehicle dynamics Overview - Universal Mechanism software includes module for simulation of railway vehicle dynamics: locomotives, freight and passenger wagons, etc. More than 40 models of various railway vehicles were created. There are diesel and electric locomotives, passenger cars, freight wagons, railcars, subway wagons and trams. The module allows the user to calculate the critical speed, analyse 3D dynamics of a vehicle or a train in time domain on straight track or curves with/without irregularities, analyze vehicle dynamics depending on wheel and rail profiles, compute natural frequencies and modes as well as root locus, create hybrid rigid/flexible models of vehicles and then estimate stress state and damage sum.
UM TRAIN MODULE FOR TRAIN DYNAMICS SIMULATION Overview - The module for simulation of train dynamics (UM Train) is developed in the program package "Universal mechanism". This module automates the process of train model creation and the analysis of obtained results.
UNIVERSAL MECHANISM UM FEM Overview - This module lets the user a possibility to introduce into a mechanical system deformable bodies, which are undergone large reference displacement but small deformation. Such an approach makes more exact results in comparison with the multibody simulation. For example the module is useful for the analysis of vibration of car body and bogie frame during the motion of a railway vehicle subject to the influence of railway track irregularities and power generating set. Such models are usually called hybrid.
UNIVERSAL MECHANISM VEHICLE MODELS Overview - A number of railway vehicles (locomotives, wagons, metro cars, trams etc.) were simulated with the help of UM Loco and a library of UM-models of locomotives are developed. The library includes models of 17 locomotives and is aimed for carrying out complex researches of its dynamics and especially safety analysis. Due to new advances technologies implemented, the process of modelling any locomotive and wagon will be extremely fast and convenient! Import of images from CAD: (SolidWorks, Autodesk Inventor and Kompas) were widely used for development of the models.
UNIVERSAL MECHANISM FREIGHT WAGON MODELLING Overview - UM MODELS OF FREIGHT BOGIES There are two the most widely used types of freight railway bogies: Y25 bogies Three-piece bogies The popularity of these bogies is caused by the cheapness of their production and maintenance. The models of these bogies were created in Universal Mechanism. Models were described according to multibody approach, where mechanical systems are presented as a set of rigid bodies, joints and force elements. These models were verified and now they are applied for solving various practical problems: Investigation of freight wagon dynamics Safety problems Wear of wheel and rail profile

STEEL SLEEPER DEVELOPMENT Overview - Although steel sleepers have been used for over 100 years, IRT initiated a research program in 1978 to assess the applicability of steel sleepers to the Australian market. Combining this effort with market developments carried out by railway companies, up to 500,000 steel sleepers per annum have been installed into Australian railroad tracks. Present domestic usage is about 13% of track, predicted to grow to 25% by 2020.
INSTRUMENTATION Overview - IRT has significant experience in the installation of temporary and permanent monitoring systems for trains, bulk ore carriers, draglines, coal trucks, shovels, etc. Systems for measuring: Strain Deflection Acceleration (vibration) Noise Temperature form the backbone of the Institute’s instrumentation capability.
TESTING OF TRACK SUB-STRUCTURE Overview - Track sub-structure layers (ballast and sub- grade/formation) can have a significant influence on track performance. Differences in the condition of sub- structure layers can cause variations in the settlement characteristics of the track. IRT has the ability to conduct controlled experiments in a laboratory environment as well as extensive test programs in the field. This enables the better understanding and cross-correlation between theoretical/laboratory test results and data collected from the actual field, under true operating conditions.
TESTING AND ANALYSIS Overview - The Institute of Railway Technology has a wide range of testing facilities and analysis capabilities including: High performance servo-hydraulic machines Versatile monitoring tools and methods Sophisticated materials examination and analysis facilities
IRT’S MECHANICAL TESTING LABORATORY Overview - TESTING MACHINES ±100kN Universal Testing machine (Static & Dynamic testing to 15HZ) 300kN Compression Testing Machine (Static & Dynamic testing to 8Hz) 450kN Compression Testing Machine (Static 800kN, Dynamic 450KN to 6Hz) ±600kN Universal Testing machine (Static & Dynamic testing to 6 Hz)
