Wheel Force Transducer
This design option allows you to activate or deactivate Wheel Force Transducer (WFT) in the specified templates.
The parameter variable pvs_wheel_force_transducer is used to model WFT. Where, '0', '1' are mapped to Inactive and Active respectively. It is used to activate appropriate group created for the WFT.
The parameter variable pvs_wft_offset is used as dependent variable which helps to offset WFT's center marker from the wheel center in global Y direction only.
Description
In Adams Car, Wheel Force Transducers are used to mimic data acquisition devices that attach to the spindle/hub (part which attaches to wheel using suspension mount communicator) by fixed joint.
By attaching WFTs, it helps with correlation to the data acquired by test engineers for wheel loads and displacements during vehicle simulations.
In Adams Car, generally the upright part is connected to the spindle by a revolute joint and the spindle is connected to the wheel by a fixed joint.
Figure 21 WFT Deactivated
If you activate WFT in the model, the WFT part connects to the spindle by fixed joint. By default WFT's cm marker is located at wheel center location.
The wft_offset parameter is where you enter the distance, the WFT is offset outboard from the wheel center (negative value means offset is inboard from wheel center). The Wheel Transducer Force measurement is performed at the fixed joint between spindle and wheel.

Adding Wheel Force Transducer to existing template
To add WFT to your existing suspension template, do the following:
1. Open the existing suspension template.
2. Go to Tools → Command Navigator.
3. Locate the macro under acar → template_builder → add > wft, enter information as shown below:
For the option: | Do the following: |
|---|---|
Model | Enter the template name in which you want to create WFT. |
Part | Select the part to which WFT part will attach by fixed joint. |
Cframe | Select the construction frame which will decide location and orientation of WFT part. |
