Principal Engineer - VORD Consulting Ltd
I was lucky to have been given whole vehicle responsibility
very early in my career and I’ve become quite good at it.
Most often I work with Bruel & Kjaer Engineering Services
as they handle the sales but I can also work independently.
- Whole Vehicle NVH Design and Development in Sweden
(2016 - 2018)
I led NVH from through the design process to prototype build
for a high performance hybrid vehicle. I enjoyed the problem
solving with minimal vehicle availability typical in low volume
projects. It was good fun combining the learning from consultancy
with my whole vehicle experience.
- Nuclear Reactor Commissioning in Finland (2017 -
Accuracy of analysis was understandably important. I worked
shifts over a cold but beautiful winter to acquire data, and
wrote some program files to perform the analysis.
- Acoustic Pack Cost Reduction (mostly 2010 - 2013)
For high volume manufacturers a £10 saving on acoustic
pack can result in millions of pounds savings every year. I
improved the process over 6 projects and ended up using the
B&K NVH Simulator to allow listenable sounds to be reconstructed
from accurate ATF measurements made in an anechoic chamber.
- Flying around the world (2010-2018)
I would rather work in the UK, but admit it is good
fun to guess what equipment to take then fly somewhere to help
a client solve a problem. So far it has gone well without too
many embarrasements and has given me a huge confidence boost.
- Completely Independent work (2003 - 2018)
Hypercar development, exhaust design in a motorsport series
to meet track regulations and sound better, high speed railway
tunnel data acquisition, and a whole lot of programming while
Aug 2001 -
Senior Consulting Engineer (Noise and Vibration),
My major project with MSX was to evaluate and resolve road noise
concerns in a C/D class saloon car. MTS IDEA-S software was used
to perform Noise Path Analysis, Multiple Input Coherence Analysis
(noise decomposition), and Panel Contribution Analysis.
Targets were generated from a listening study using MTS Sound
Quality, I coordinated CAE, ride and handling, and workshop teams
to design and implement modifications to the development vehicle.
The completed vehicle surpassed targets and the success of the
project earned MSX further projects with the client.
Feb 2000 -
Senior Noise and Vibration Engineer, Lotus Engineering
I carried out the NVH development programme on a client supercar
project with an aluminium and carbon fibre structure. My optimisation
of body sealing and acoustic pack reduced interior noise and improved
sound quality while substantially reducing weight and cost. Combining
LMS road test data with a 4-post shaker technique I tuned powertrain
and damper mountings for secondary ride. Other activities included
powertrain sound quality, wind noise, and driveline development.
Using the very effective Apex software to carry out predictive
design work on exhaust silencers for two new models (one of which
was turbocharged), I was able to reduce the size and weight of
the exhaust silencer while improving the quality of the exhaust
Most fun was selling the idea of NVH to a senior project manager
at Lotus. At the time they thought NVH would add weight and cost.
He allowed me just a week to carry out a powertrain sound quality
exercise for a model year update of their lightweight sports car.
I combined objective and subjective assessments with LMS sound
quality techniques. The NVH treatment I proposed reduced vehicle
weight and cost, and reduced unpleasant noise. I also tuned the
intake system to give the engine a more powerful and sophisticated
note. The new NVH characteristics were highly praised by the automotive
Noise and Vibration Refinement Engineer, Rolls-Royce
& Bentley Motor Cars
Despite my lack of experience at the time, Bentley were kind
enough to make me responsible for the NVH performance of putting
the old school V8 back into the Arnarge. At the concept stage,
in parallel with development of the strategy, timing and budget,
I was able to demonstrate the cost, weight and NVH benefits of
a fundamental change in differential mounting strategy. This new
strategy was included in the project specification and worked
I instigated and managed a series of CAE bodyshell and suspension
models to lead the design process. These models were successfully
used to reduce body noise sensitivity, de-couple vehicle modes
and to develop the engine mounting strategy. I appointed an external
supplier to carry out the development programme under my guidance.
This included the use of sound quality techniques to address specific
powertrain and road noise concerns.
Validation Engineer, Rolls-Royce and Bentley
I acted as a validation engineer at Bentley before moving into
NVH. As a validation engineer I was responsible for devising and
carrying out rigorous tests on powertrain and chassis systems.
Other responsibilities included developing and managing timing
plans for prototype vehicle usage, and compiling a monthly report
to communicate validation programme status to the project team.
I enjoy learning practical crafts and writing about them on the internet.
Metalworking was my first interest and mig-welding.co.uk
is my most popular website.
My classic motor cars are covered on vord.net,
aston-v8.co.uk and renault4.co.uk.
I'm currently busy restoring
an old pub and doing most of it myself. I've figured out bricklaying
and am trying to perfect woodwork.
I like internet coding and ThermoTun_Online
is by far the trickiest site I have ever coded - the site looks basic
from the outside, but inside does some fabulous things that the internet
just isn't designed to do.
