Virtual Acoustic Prototyping of EV E-Compressor; noise prediction up to the drivers ear
This presentation illustrates the Virtual Acoustic Prototyping (VAP) of an E-Compressor’s vibration up to the driver’s ears. The excitation / loads of the compressor are measured using Equivalent / Blocked Forces. The vehicle model is built from FEM and Test-Based models of a benchmark vehicle and prototype compressor. Here, use is made of the Virtual Point Transformation (VPT) technique to make sure that the Test-Based Model and Forces are accurate.
Maurice has worked as a business developer at VIBES since 2022, with a background in technical sales. Throughout his career he has gained experience with testing, validation and production in advanced industries like automotive, aerospace, gas turbines and large compressors.

Rebirth of the Parallel-Twin: The Sound of the ICE Swan-Song
As the automotive industry directs R&D budgets away from IC engines and towards electrified powertrains, the motorcycle industry is still developing new-and-improved engines. This presentation discusses the discerning customer’s NVH expectations and describes the evaluation techniques that allow engineers to meet those expectations. The paper also reviews trends in powertrain technologies currently employed by leading manufacturers, and their ability to deliver the engaging riding experience while still meeting legislation requirements.
Matt has worked within Ricardo’s Noise & Vibration Department since graduating from Warwick University in the year 2000, after initially working predominantly on projects for clients within the automotive industry he now specialises in NVH for the motorcycle and rail industries. He is himself a keen motorcyclist that has never been known to give a straight answer to the question “how many motorcycles do you currently own?”.
David Ewbank, VI-grade
Virtual Testing in an X-in-the-Loop integrated accelerated development environment
VI-grade’s presentation will showcase the X-in-the-Loop integrated virtual test approach for accelerated vehicle development. The combination of driving simulators and Hardware-in-the-Loop technologies enables customers to reduce the number of physical prototypes towards achieving virtual sign-off, a major step towards “zero prototypes.” The presentation will demonstrate the realization of this approach in both driving simulator and in-vehicle testing environments, resulting in true digital twins.
David Ewbank, a Technical Specialist with 17 years of experience at VI-grade, has a particular expertise in real-time simulation and driving simulators. His career began at MIRA in road load data measurement and objective vehicle dynamics before progressing into computer simulation. He worked with MDI and MSC Software before joining VI-grade, where he is also the Technical Manager of the VI-Certified Program, validating 3rd party software operation on VI-grade simulators.
Jonathan Deacon, Oxford Technical Solutions Ltd
The Path to Combining Localisation, Perception and Simulation
Accurate and reliable input data into simulations is critical when thousands of validation tests are required to approve active safety features. An accurate representation of the world (a digital twin) is needed, alongside precise navigation data of the vehicle and sensors, enabling different perception algorithms to be developed without repeatedly collecting new data. Open-road validation of the ADAS feature can be done, with confidence that localisation is accurate and reliable.
Jonathan is a Product Manager at Oxford Technical Solutions (OXTS), the industry leader for localisation in test and validation of vehicle dynamics and ADAS applications. With a strong foundation in the technology, Jonathan is working on applying innovative Multi-Sensor Fusion navigation techniques to the mapping and autonomy sectors. He holds a Masters in Mechanical Engineering from the University of Sheffield and holds associate membership of the IMechE.
John Bouchard, Stress-Space
Residual Stress Determination Using Multiple Methods
This presentation will illustrate how multiple measurement techniques can be applied in tandem to map residual stresses in engineered components. In particular, early results from a Proof-of-Concept experiment (March 2023) at the ISIS Neutron and Muon Source (Harwell) will be presented. This pioneering work demonstrates, for the first time, the feasibility of simultaneously measuring surface residual stresses by Adaptive X-ray Diffraction and bulk residual stresses by Neutron Diffraction.
Professor John Bouchard (FIMechE) led materials engineering research at the Open University (2008-2020) following a successful industrial career as a structural integrity specialist. John has published over 140 papers with research interests in residual stress engineering, fracture mechanics and the performance of structures at high temperature. John is a founder-director of Stress-Space Ltd that offers residual stress determination services using multiple techniques including the contour method, slitting, X-ray and neutron diffraction.
Matthew Oxborrow, RALSPACE
Verification for Digital Image Correlation for Pyroshock Testing
This presentation investigates and verifies the use of digital image correlation (DIC) for the purposes of measuring a shock test. It compares the shock response spectrum (SRS) of both the data obtained using DIC and using traditional accelerometer methods. Other areas such as the homogeneity of the system and the repeatability of the system are also investigated.
Matthew is a Test Engineer at RAL Space working on vibrational and shock testing for space hardware. He has a degree in Mechanical Engineering from the University of Birmingham and has worked at RAL for 4 years. He has run shock tests for numerous projects, some of which have successfully launched.
