OUR TECHNOLOGY
Meet needs with evolving technology.
The functions and performance expected for rolling stock such as safety, security, comfort, economy, and environmentally friendly are becoming increasingly sophisticated.
We manufacture the best rolling stock to meet these needs by striving everyday and enhancing the latest design, analytic technology and production technology.
In addition, we propose rolling stock as a solution that achieves high safety and reliability at a competitive cost, by coordinating with our group companies’ comprehensive railway technologies, such as maintenance and operation and IoT technology.
MANUFACTURING LINE
High-mix Production Capacity
We have a wide variety of manufacturing lines such as the line dedicated to stainless steel vehicles, the flexible line capable of handling aluminum vehicles such as those used for Shinkansen trains, the line for manufacturing robust and high-precision bogies, and furthermore, the line only in Japan dedicated to railway containers, enabling us to achieve the optimal production system according to each product.
MANUFACTURING LINE
RESEARCH AND DEVELOPMENT
Development of "sustina" Carbody Structure
The “sustina” carbody structure has been developed with the aim of creating next-generation commuter vehicles achieving high safety in spite of being a lightweight stainless steel carbody structure.
To further make use of the maintenance-free characteristic of stainless steel, which keeps its beautiful shine for a long time, an unprecedented flatter and refined outer plate has been achieved by laser welding.
The “sustina” series establishes the next-generation standard based on the carbody structure technology that features high reliability with excellent cost performance.
RESEARCH AND DEVELOPMENT
Research toward Comfortable and Quiet Spaces
High-speed vehicles require a variety of advanced technologies. Among these, especially one of the important items is quietness inside the vehicle. To enhance a passenger comfort, the interior noise reduction technology is indispensable, and we are focusing its efforts on its development.
We are researching various analytical methods to analyze the current noise situation and predict the effectiveness of reduction measures in advance. Among them, simulations using the SEA method (Statistical Energy Analysis) to analyze the transmission of acoustic energy have yielded results that closely match the actual measurements with a high accuracy, contributing to the realization of the quieter vehicle structure.
Multi-angled Research and Development
At our company, not only the research and development department, but also every employee is aware of problems and strives to improve technology every day.
On manufacturing site, we are conducting a number of research aimed at enhancing measurement efficiency. These include “the development of a non-contact carbody distortion measurement mechanism” utilizing laser the distance meter and ”efforts to improve painting quality”, enabling automatic painting machines to accommodate diverse designs.
In addition, we are working on technological innovation in many areas, collaborating across departmental boundaries to develop the “Freesia Console,” which aims to unify and standardize the increasingly complex area around the driver’s cab console.
INDUSTRIAL DESIGN
Railway Rollingstock Fusing Beauty and Functionality
The beauty of railway rolling stock is one of the major attractions that draws passengers to the railway.
Attractive vehicles are born by fusing diverse needs such as intended use, safety, economy, environmental consideration, ease of use, and comfort into a refined design, in addition to the aesthetic beauty with a sophisticated design.
The exterior design serves as an icon for the towns along the railway line and also clearly expresses the vehicle’s functionality and the characteristics of the line.
In the interior design, we create a comfortable passenger saloon,
which is filled with kindness, based on the concept of human-centered design, incorporating arc-shaped UD handrails (Received the Japan Ergonomics Society Good Practice Award Grand Prize) and utilizing VR-based evaluations.
INDUSTRIAL DESIGN
MECHANICAL DESIGN
Sophisticated Design with 3D CAD
In our vehicle design, we make full use of the latest 3D CAD to achieve new value including not only further improvements in safety, comfort, and economy, but also ensuring sufficient forward visibility and creating complex carbody shaping.
We consider the design from multiple perspectives, including determining the structure, mechanism, and shape, checking the weight balance and interference, selecting the production method, and confirming the operability and maintainability.
In addition, by CAD-CAM linking to conduct machining in the production process based on 3D data, high quality and high precision products are produced exactly as intended by the designer.
MECHANICAL DESIGN
ANALYSIS
Extensive Technical Analysis for Safety and Comfort
The evaluation of safety and comfort required for railway vehicles is now impossible without computerized analysis technology.
The evaluation items are diverse and include strength, crashworthiness, vibration characteristics, interior air conditioning performance, noise characteristics, and aerodynamic characteristics, and each one is closely related to important performance such as safety, comfort, and environmental compatibility.
We utilize analytical simulations using cutting-edge servers linking to 3D CAD from the early design phase to develop products with safety and comfort.
