Dynamic Wheel Forces for subsequent Component Design
Dynamic Wheel Forces for subsequent Component Design
(OP)
Dear Experts,
I have just come across products online that capture dynamic wheel forces for cars and heavy vehicles by attaching the device to wheels etc.
Is data from such a device commonly used by OEM's to help design suspension and hub components due to forces acting on the wheel?
Or what is the typical instrumentation used to acquire wheel load data so that life of components can be evaluated via cumulative damage due to various wheel loads etc?
This data acquisition would be relatively new to my company so I'm trying to gather some data on how this type of approach might be used by OEM's.
Any information will be greatly appreciated.
Best Regards
Eddie

Another method used is to individually strain gauge components that are part of the suspension in order to determine the respective loads. This way you are directly measuring the component in question.

In addition to the wheel force transducers and the strain gages mentioned by TVP, accelerometers are used also.

We used to strain gauge the important directions for each component, this is still used for correlation of the WFT data. That is, with 24 channels of WFT data we probably run another 10-20 strain gauges as correlation. The less correlation data you have, the quicker and easier the correlation process.

Do you consider the WTF to be an integral part of the design process for automobile design?
I guessing this data can be used to understand peak loads and load spectra for fatigue/durability design, something that we do not have at the moment.
We would have done some physical testing some time ago to establish load targets which would be a 'one fit for all' for any products we design.
I am just wondering should our firm consider something like this. Is there any ammunition could use to convince my boss to consider this?
Any information will be appreciated,

If you are doing FEM, the data could be used to verify the model.

However, one way or another you need the stress data, I don't think that is negotiable.
