Malcolm Hardy, Principal Engineer Vehicle NVH at Jaguar Land Rover presents at the UK Altair Technology Conference 2019. With an increasing number of vehicle programmes, propulsion variants and body styles on a range of different vehicle architectures, it is increasingly challenging to ensure that control models are consistent to allow comparable CAE assessment.
This is essential to allow key engineering decisions to be made and becomes even more critical as Jaguar Land Rover develop Full Vehicle NVH Simulator models to enable subjective assessments and sign-off before a physical prototype is built. This leads to a requirement for a consistent and robust process, independent of the user, for assembling models and applying load cases across all programmes, aligned to demanding gateway timing.
In response to these requirements, Jaguar Land Rover are integrating Altair’s NVH Director into their Vehicle NVH development process. This has enabled the formalisation of model requirements and processes, ensuring that vehicle models are built consistently with standardised load cases and post processing. This allows the reporting of status more efficiently than previously, allowing more time for engineering development and the future ability to stochastically assess the robustness of engineering solutions and likelihood of error states.
