Meeting stringent industry standards in railway seat design requires precise analysis and structural optimization. In collaboration with MK Seats, the ENDEGO team conducted validation and optimization of the driver’s seat bolted joints, ensuring full compliance with technical and strength requirements.
MK Seats GmbH
The client requested verification of a regional train driver’s seat to ensure compliance with VDI 2230 guidelines for bolted joints, taking into account the loads defined by VDV 152. Additionally, the task included optimisation of the bolted joints for strength in case the criteria were not met.
An advanced FEA model of the seat was developed, including a detailed representation of the bolted joints. A comprehensive strength analysis of the structure and joints was performed in accordance with relevant industry standards. In close collaboration between the MK Seats team and ENDEGO CAE experts, the bolted joints were optimised, ensuring full compliance with strength and technological requirements.
The outcome was an optimised and validated driver’s seat design, guaranteeing safe and reliable operation for many years. This enabled the client to expand its portfolio with more complex solutions for the railway sector and strengthen relationships with a key OEM.
Rolling stock OEMs can reduce prototype risk by defining the validation scope early, connecting design with FEM analysis, checking critical joints and interfaces, and preparing traceable evidence before manufacturing begins. Simulation does not remove the need for physical testing. It helps make the prototype a confirmation of a mature design rather than the first place where major structural weaknesses are discovered.

Efficiency, range, performance and durability depend on the combined operation of the motor, inverter, battery, battery management system (BMS), cooling system, transmission, control software and mechanical integration. Electric powertrain development should therefore address the complete system and the vehicle’s real operating profile from the outset.
