Analysing the root causes of bracket vibration and proposing a solution to avoid the resulting failures.
Analysing the root causes of bracket vibration and proposing a solution to avoid the resulting failures.
Failure of a wheel lubricator bracket due to strong vibration.
The work started with a finite element analysis (FEA) to determine the actual loads. In particular, vibrations were analysed in detail. The data obtained was used in post-processing using: fast Fourier transform (FFT) and white noise elimination. The acquired data were transferred to the FEA model and correlated with the FEA test.
The solutions used allowed the stiffness and mass topology to be optimised. Thanks to a comprehensive approach – including root cause analysis, thorough examination of the acquired data and optimisation of the topology – it was possible to deliver an error-free, robust solution. The result was an improved design used to produce an implementation-ready product, remaining in use from its initial implementation.
Bus accessibility is not an afterthought but a set of requirements that influence the layout of the floor, suspension, and passenger compartment. A low entry height, space for a wheelchair, or the ability to lower the vehicle at a stop all stem from specific dimensional and functional requirements. That is why accessibility should be considered as early as the vehicle concept stage, rather than only during interior design.
Read moreCybersecurity 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.
