Measuring Wheel Forces and Torques

Determining wheel force and wheel torque is essential for the development of modern vehicles. One common way of measuring drive torque is via strain gauges on the original output shaft. Another equivalent method is measurement via an explicit torque sensor, which is fitted between the rim flange and the wheel hub. Choosing the best measurement technique is determined by what you are trying to learn from the measurement. As with torque, structural parts of the vehicle, such as chassis parts, can also be equipped with strain gauges for force measurement. However, if you want to measure forces and torques combined with high precision, you must use a Wheel Force and Torque Transducer. This measures the three forces on each wheel in the F_x, F_y and F_z directions as well as the corresponding torques between the wheel hub and rim.
