Remaining Life Evaluation Program -
UIWANG, South Korea – FEBURARY 16 – The
Korea Railroad Research Institute (President: Dr. Seok-youn Han) has developed the
Rolling Stock Remaining Life Evaluation Program and obtained the Level 1 Good
Software (GS) certificate, a national certification program based on the
standards of the International Organization for Standardization (ISO).
The Rolling Stock Remaining Life
Evaluation Program is a software program that quickly and accurately performs
complete rolling stock safety diagnosis to ensure safety of the trains reaching
their design life.
Thanks to the Level 1 Good Software (GS)
certificate, the program has been registered in the digital service mall
operated by the Public Procurement Service of the Korean government and has
also been designated for the Unit Price Contracts for Third Parties Program and
the Preferential Purchasing Program for Public Organizations.
A Good Software (GS) certificate is a
national certification program awarded to software with excellent functional
capability, efficient performance, compatibility, usability, reliability and
security in accordance with international standards of the International
Organization for Standardization (ISO).
The Rolling Stock Remaining Life
Evaluation Program calculates remaining life by measuring sensor signals on
vulnerable parts with complex structures that are welded together, such as
railway car-body and bogie.
The program has significantly reduced
evaluation time from over a week to less than few hours.
In addition, since it can simulate various
operating conditions in advance according to field situations, it is possible
to make plans for utilization of rolling stock as passenger numbers increase.
“KRRI
will expand its research and development by adding a real-time online function
to monitor the aging of rolling stock in real time, so that risk can be
identified in advance,” said KRRI Chief Researcher Hyun-kyu Jun.
“Rolling
stock designed to operate for more than 30 years ages slowly due to the fatigue
loading during the railway operating service. Therefore, predicting remaining
service life is very critical to ensure safety,” said KRRI President Dr.
Seok-youn Han. “KRRI will make greater efforts to develop prestigious K-railway
technologies that keep people safe based on cutting-edge science and
technology.”
