In order
to realize the vision of "contributing to railway development and social
progress with technological innovation", Japan Railway Comprehensive
Technology Research Institute (referred to as "Railway Comprehensive
Research Institute") has formulated the scientific research development
plan for 2020 ~ 2025 on the basis of predicting the development prospect of
railway technology in the next 10 to 15 years. The Railway Research Institute
has formulated four research and development goals: First, "improving
safety", including strengthening the ability to resist serious natural
disasters; The second is "low-cost realization", including operation
and maintenance labor-saving countermeasures and technologies; The third is
"coordination with the environment", including power grid emission
reduction countermeasures and technologies; Fourth, "convenience
improvement", including speeding up the maximum operating speed.
In order
to achieve the above goals, the Railway Research Institute has formulated the
basic policy of research and development, including carrying out research on
technologies related to railway safety improvement, implementing railway system
innovation based on digital technology, exerting comprehensive strength to
create high-quality achievements, enhancing the international influence of
railway technology, and creating a workplace environment that can give full
play to employees' abilities and reflect labor value.
The
Railway Research Institute has formulated the key tasks of scientific and
technological development in the coming period from three aspects:
-Carry
out in-depth forward-looking technical research in view of the social changing
trend and the future railway development needs.
-Facing
the actual needs of current railway operation, carry out practical
technological innovation.
-Deepen
the basic research of railways, and carry out research on meteorological
disaster prediction, vehicle running safety, aging damage mechanism and
inspection methods, friction loss and long life.
On the
basis of the above three key tasks, Japan Railway Comprehensive Technology
Research Institute has formulated six forward-looking technical research tasks,
as follows:
(1) Strong
response to natural disasters. Disaster risk assessment is carried out
according to real-time meteorological data, which provides auxiliary support
for train operation and improves railway transportation efficiency. The
construction method of rapid emergency repair after heavy rainfall disaster is
constructed, which accords with the residual bearing capacity of slope and
embankment.
(2)
Automation of train operation. Research on real-time train position monitoring
technology based on satellite positioning, deepen the innovation of anomaly
detection technology in and along the railway, and promote the research of
wireless control technology of ground equipment and vehicle operation control
technology.
(3)
Labor saving in maintenance. Implement digital maintenance, carry out research
on automatic diagnosis technology of line bridge and tunnel state based on
on-board test mode, build a comprehensive analysis platform of facilities and
equipment data, and promote research on early anomaly detection technology such
as high impedance grounding fault based on power grid monitoring.
(4) Low
carbonization of energy consumption. Construct railway power storage system,
develop research and development of energy-saving devices such as
high-performance rectifiers, promote research on energy-saving driving mode of
trains, and realize low carbonization of railway power grid.
(5) Noise
reduction of high-speed lines. Using low-noise train model running test-bed and
high-speed pantograph-catenary test-bed, the aerodynamic noise of running gear
and tunnel micro-pressure wave are studied, and pantograph with high current
collection performance and low noise performance which can adapt to higher
speed is developed.
(6)
Integration of test and simulation. Using virtual railway test line, the
coupling dynamics simulation research of vehicle motion, pantograph-catenary
relationship and wheel-rail rolling contact is carried out Research and develop
simulation software for evaluating the loss state of current collecting
materials and safety evaluation of running vehicles when pantograph is pulled
off-line; Carry out research on microstructure simulation technology of new
materials; A digital wind tunnel system is constructed to simulate large-scale
low-noise wind tunnel test by numerical calculation.
