Instrumentation

At TTS we understand that accurate testing and/or analysis can only be achieved with knowledge and understanding of the inputs the product is subjected too. This is valid whether it is a complex sub-assembly, complete vehicle or even just a simple bracket or fastener.

Correct instrumentation is crucial to obtaining accurate and relevant data allowing the design engineers to understand exactly what is happening to their part whilst it is installed and subjected to common inputs.

TTS engineers have extensive experience in many aspects of instrumentation, from simple one off temperature measurements to full vehicle instrumentation exercises using strain channels, pressures, temperatures, displacements, accelerations, etc all being acquired simultaneously.

This 3 axis loadcell was designed and machined by TTS engineers to measure loads on a small engine mount.
The loadcell proved to be very effective with good output and very little cross-coupling.
We have since used this design for other scenarios

Towbar 100

A requirement for measuring forces imparted to the towing fixture led to this tow ball being strain gauged and calibrated to act as a loadcell in both longitudinal, lateral and vertical planes.
The loadcell helped prove that the towbar fixture and vehicle structure needed a small amount of extra strength to complete the designated durability.
The quick release connectors allow the towball to be used on a variety of vans in the fleet with minimum disruption.

Photoelasticity (or PhotoE) can be useful to visualise the stress in certain applications.

Here TTS engineers have used it on a Macpherson strut top turret before the application of strain gauges. Photo E can be an invaluable tool in the development process.
This is one of the many services TTS offer to help you validate and improve your products.

TTS engineers performing a data collection exercise in Russia using Wheel Force Transducers, accelerometers and displacement sensors on all four wheels.

This vehicle was driven across Europe to the proving grounds in Russia.
The data was then analysed using Glyphworks to compare test schedules from other international markets and to produce durability rig drive profiles.
TTS engineers have used MTS and Kistler WFT’s in the past.
