Rail systems are among the most important and effective modes of transportation used for both public and freight transport worldwide. Capable of carrying both passengers and cargo, rail systems are designed and manufactured according to strict standards in terms of safety and durability. To ensure the smooth and safe operation of these systems, a high level of expertise in engineering is required. In this context, as FE-TECH, we offer comprehensive engineering services for rail systems.
In this article, we will examine the engineering solutions we provide in the field of rail systems, and provide information on bogie and vehicle body design, analyses, testing services, and the international standards used in our projects.
One of the most fundamental and critical components of rail vehicles is the bogie and vehicle body. These two components are key determinants of a vehicle's durability, safety, and longevity. At FE-TECH, we design bogies and vehicle bodies in accordance with international standards. In this area, we conduct strength analyses in compliance with standards such as VDV 152, EN 12663, and EN 13749.
The bogie is the movable subsystem to which the wheels of a rail vehicle are attached, and it is critical for the vehicle's handling, stability, and driving safety. In bogie design and analysis, we work according to the following standards:
With these analyses, we optimize our bogie designs to suit both passenger and freight capacities. By enhancing durability, we aim to minimize the risk of potential damage.
Vehicle bodies are one of the most important components ensuring both the structural integrity of rail vehicles and the safety of passengers. At FE-TECH, we optimize vehicle body designs according to international standards. In this scope, the services we provide include:
We subject our body designs for rail vehicles to strength and durability tests to achieve long-lasting and safe structures.
The strength analysis of rail vehicles is not only important during the design phase but also throughout their operational lifetime. Continuous vibrations, load variations, and challenging conditions can lead to fatigue in welded joints. Therefore, fatigue calculations of welded joints are a critical part of our engineering services.
Weld fatigue calculations, conducted according to the DVS 1612 standard, are especially used to analyze the long-term durability of welded joints made with steel materials. These calculations ensure that the joints perform for a long time without structural issues such as deformation or cracking.
Some of the key factors considered in weld fatigue calculations for rail vehicle projects include:
Vehicle dynamics and crash analyses are extremely important for the safe operation of rail systems. These analyses are conducted to optimize the vehicle's handling, stability, and overall performance during movement. Additionally, various tests are carried out to ensure passenger and cargo safety in case of potential collisions.
Crash analyses and vehicle dynamics tests are especially critical for passenger-carrying vehicles such as high-speed trains, trams, and subways. With these tests, we ensure that vehicles operate safely even under challenging conditions.
For rail systems to function efficiently, rail-wheel compatibility is extremely critical. Ensuring that the wheels are compatible with the rails allows for the vehicle's safe and efficient movement. At FE-TECH, we optimize vehicle stability and handling through rail-wheel compatibility analyses.
Additionally, comfort analyses are conducted to improve the travel experience of passengers. These analyses measure factors such as vibration levels, indoor temperature, and overall passenger comfort, with the aim of providing a highly comfortable travel experience.
At FE-TECH, we provide engineering solutions for both passenger and freight wagon projects in rail systems. In passenger vehicles, we offer solutions that provide high levels of safety and comfort by conducting vehicle dynamics, bogie design, body strength analyses, and comfort analyses. In freight wagon projects, we improve performance by conducting body design revisions and durability analyses for high-capacity wagons.
The performance of HVAC systems in rail vehicles is crucial for the thermal comfort of passengers. At FE-TECH, we perform HVAC system performance analyses and tests in accordance with the EN 14750 standard. These tests allow for the analysis and improvement of factors such as air velocity distribution, temperature levels, and overall ventilation performance inside the vehicle.
Additionally, aerodynamic analyses conducted according to the EN 14067 standard focus on increasing vehicle energy efficiency. These analyses reduce the vehicle's air resistance, thereby optimizing energy consumption.
As FE-TECH, with the engineering solutions we offer for rail systems, we provide reliable, durable, and internationally compliant services to companies in the sector. With critical engineering services such as bogie and vehicle body design, strength analyses, weld fatigue calculations, vehicle dynamics, and crash analyses, we aim to maximize safety and performance in rail systems.
All our engineering services, from passenger and freight wagon projects to HVAC systems, meet the industry's most demanding needs and fully comply with international standards.
