At the start of the year, the Aston Martin F1 team unveiled their new AMR26, boasting an innovative design and enormous expectations. However, as pre-season testing began, vibration issues were detected, linked to the integration of the power unit into the single-seater’s chassis. According to specialist media, these issues did more than just hamper the car’s handling; they actually damaged sensitive components, including the battery, and limited the mileage available to the team during a critical developmental phase.
The engine manufacturer, Honda, indicated that the motor showed acceptable vibration levels on the test bench, but it appears those vibrations were amplified to alarming levels once mounted within the completed car.
The interesting takeaway is not about pinpointing a specific failure—whether it be the chassis or the engine—but rather understanding the complexity of the phenomenon. In a racing car, every structural element has mass, stiffness, mounting points, and its own vibration modes. Consequently, when the engine transmits certain frequencies to the assembly, the chassis can act as an amplifier if any of those frequencies coincide with its natural modes.
The result can compromise sensitive components such as batteries, electronics, mounts, or connectors, while also impacting stability, reliability, and the driver’s ability to extract performance.
This type of situation perfectly illustrates why advanced simulation has become a critical tool in engineering. It is not about replacing physical testing entirely, but about reaching that stage with significantly less uncertainty. With solutions such as SIMULIA by Dassault Systèmes, engineering teams can study the dynamic response of complex structures, detect potential resonances and evaluate vibration transmission, analyse how subtle changes in stiffness, geometry, materials, or joint positions can modify the system’s global behaviour, and also link these results with durability studies to estimate the impact of repeated vibrations on critical components before hitting the track.
The key lies in moving from validation focused on individual parts to a system-wide vision. An industrial machine, an electric vehicle, a turbine, medical equipment, or an aeronautical structure does not necessarily fail because a single part is weak, but because the interaction between various components generates conditions not accounted for in individual analyses.
Simulation allows these interactions to be explored earlier, in greater depth, and at a lower cost than a strategy based solely on physical prototypes. In an environment where design margins are increasingly tight, detecting a problematic vibration in the virtual phase can be the difference between correcting a detail in time or redesigning under pressure once the problem is already on the track, on the factory floor, or in the customer’s hands.
