Vehicle Technology Division

Profile

Our division is composed of Vehicle Dynamics, Vehicle Noise and Vibration, Vehicle and Bogie Parts Strength, Hydrogen and Sustainable Energy, Traction Systems, and Braking Systems. Making solutions for problems concerning vehicle structure and control is our mission to progress R&D to the next generation.

Introduction

The Vehicle Technology Division aims to realize safer, more comfortable, more efficient, and more convenient 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:
- running safety
- comfort regarding motion, vibration, and sound
- strength and durability of wheelsets, bogie frames, and car bodies
- safe and efficient drive and braking systems
- the application of hydrogen energy
- the energy saving of power supplies and equipment.

Laboratories and their research fields

Vehicle Dynamics

Vehicle Dynamics is in charge of running safety assessments of the derailment and overthrow of railway vehicle, measurement and simulation of vehicle characteristics of vibrations, and development of new technologies about improving riding comfort and safety.

Vehicle Noise and Vibration

Vehicle Noise and Vibration is in charge of technology about assessment, analysis, and decreasing of the vibration and the interior noise of vehicles to improve the ride comfort of passengers.

Vehicle and Bogie Parts Strength

Vehicle and Bogie Parts Strength is in charge of the evaluation of fatigue strengths in the wheel, axle, bogie frame and car body, and the non-destructive testing methods such as the ultrasonic flaw detection, and the crashworthiness of vehicle body, and the fire safety of vehicle body.

Hydrogen and Sustainable Energy

Hydrogen and Sustainable Energy is in charge of hydrogen technology such as fuel cell vehicle and the evaluation and proposal of energy-saving technologies in vehicle.

Traction Systems

Traction Systems is in charge of research and development related to traction systems, including vehicle energy saving and energy storage, decarbonization of diesel cars, re-adhesion control, and condition monitoring of vehicle traction equipment.

Braking Systems

Braking Systems is in charge of technical development and evaluation of whole mechanical brake system in not only commuting train and freight train but also high-speed train like Shinkansen.
