Modernization of the structure of the front of the ED72 electric multiple units, taking into account static, fatigue, and crashworthiness requirements.
Modernization of the structure of the front of the ED72 electric multiple units, taking into account static, fatigue, and crashworthiness requirements.
The upgraded ED72 unit front structure met all the requirements in terms of functionality, static, impact, and fatigue strength.
Cybersecurity in rolling stock has moved beyond a late-stage IT check and become a vehicle-engineering discipline. Network architecture, supplier responsibilities, software updates, secrets management and vulnerability handling all have to remain workable throughout a fleet’s service life.
Read moreRolling 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.
Read moreAn electric motor is only one component of a vehicle’s e-drive system. 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.
