What are the most significant engineering challenges ahead for electrification, and how DSD is handling new requests for electrified propulsion system test & development?
Automotive Testing Technology International interviewed David Kelly, Development and Testing Director at DSD.
There are three significant engineering challenges to be considered:
New propulsion systems must be designed, tested and optimised more effectively than any predecessors. This requires a new engineering method based on a complete system approach.
Designing the best individual components does not necessarily result in the best product.
We have pioneered a simulation process to optimise an EV powertrain for cost and range as a complete system. The Electrified Powertrain Optimisation Process (ePOP) evaluates thousands of powertrain permutations and enables clients to “back the right horse” in the concept phase, significantly reducing risk.
A system approach can also help with NVH optimisation, where many challenges remain. It requires the characterisation of objectionable noise in the vehicle cabin and the effective correlation of all that includes back to powertrain excitation and response. This expands the analysis environment enormously and relies on tools that can generate and process large amounts of data then present the output in a way that can be used to make decisions.
