Abstract (en)
[origin: GB2506532A] Computer aided engineering for designing a driveline comprises the steps of: creating a single parametric description of the driveline; analysing the parametric description for performance using one or more failure modes. The mathematical model may provide a dynamic analysis using a discrete model, using nodes sufficient for a defined frequency range and in which degrees of freedom per node may have linear or non-linear characteristics suitable for the failure mode. The user may assess performance against a design target and the software may optimise performance by amending the parametric description and repeating the analysing step. The driveline may be an electric motor/generator and a gearbox with associated gear mesh roller bearing stiffness and/or unbalanced magnetic pull at a given speed and load operating point. The model may analyse vibration power being passed from bearings to housing in response to torque ripple and/or transmission error. Engineering performance may include vehicle performance, energy/fuel efficiency, exhaust emissions, stress, durability, fatigue, cost, thermal, noise performance, manufacturability, failure due to dynamic input loads, speed and gearbox ratio changing.
