Abstract
We developed a characteristic identification system for devices of railway
vehicles which is an essential component in a system of ‘Virtual Running Test
Environment’ based on Hardware In the Loop Simulation (HILS) technology, as
developed by Railway Technical Research Institute (RTRI) to replace running
tests with bench tests. This report describes the outline and the effect of the
characteristic identification system for oil dampers using a Neural Network
(NN), which estimates input-output relation of the target in 6 degree-of-freedom
using multi-axis damper test equipment.
Keywords: railway vehicle, oil damper, Neural Network, hardware in the loop
simulation, characteristic identification.
1 Introduction
Running tests are indispensable to develop the railway vehicle. In Japan,
however, a great amount of cost and time are required for the tests. In addition,
most of the running tests take place on service lines since there is no test truck
available for exclusive use in Japan. Accordingly, a number of test and the test
condition are restricted.
It is likely to lead to shortening and the quality improvement of the
development process if it comes to be able to reproduce a real railway vehicle
motion in detail by some bench examinations.
Then, we work the construction of ‘Virtual Running Test Environment’ based
on Hardware In the Loop Simulation (HILS) technology (Fig. 1), which replaces
running tests with bench tests. It is necessary to mount the greater part of the
railway vehicle components on the simulation model as software, because it is
impractical to mount all of the railway vehicle components as hardware in
Keywords

simulation, characteristic identification.
