Vehicle Structure Technology Division
Profile
Our division is composed of Vehicle Dynamics, Running Gear, Vehicle Noise & Vibration, and Vehicle & Bogie Parts Strength. Making solutions for problems concerning vehicle structure is our mission to progress R&D to the next generation.
Introduction
The Vehicle Structure Technology Division aims to realize safer and more comfortable railway vehicles through research and development of products and methods that meet the needs of railway operators.
Specifically, we are conducting research and development on safety against derailment of the vehicle, running stability regarding hunting motion, ride comfort at high speed and on curves, comfort regarding motion, vibration and sound, strength and durability of wheelsets, bogie frames and car bodies.
Laboratories and their research fields
Vehicle Dynamics
Vehicle Dynamics is in charge of assessments of running safety on the derailment and overthrow of railway vehicles, working on elucidating the phenomena related to behavior of railway vehicles such as contact force of wheels and vibration of vehicles, from both the measurement and the simulation.
Running Gear
Running Gear is in charge of development of new technologies about improving riding comfort and safety such as the vertical vibration reduction control systems, upgrading carbody tilting systems, steering systems for reducing lateral force, and monitoring systems for detecting bogie parts failure.
Vehicle Noise & Vibration
Vehicle Noise & Vibration is in charge of technology about assessment, analysis, and decreasing of the car body elastic vibration and the interior noise of vehicle / car motion analysis with the multi body dynamics / assessment of vehicle motion characteristics by hybrid simulators.
Vehicle & Bogie Parts Strength
Vehicle & Bogie Parts Strength is in charge of the evaluation of fatigue strengths in the axle, bogie frame and car body, and researches in the non-destructive testing methods such as the ultrasonic flaw detection, and researches in the crashworthiness of vehicle body.
