Evaluation of Different Designs of Wheel Force Transducers (Part II)

A novel method for producing low cost dynamometric wheels based on harmonic elimination techniques

“…A literature review of wheel force transducers can be found in [6,7]. In this case, the sensors are not directly placed in the original wheels of the vehicle, but the wheels are replaced by a standard wheel force transducer which is connected by adaptor parts to a rim and to the vehicle hub.…”

“…Consequently, in order to fully understand the dynamic behaviour of the vehicle, accurate experimental data of these contact forces and moments are needed. Several methods can be found in the literature for measuring the forces and torques generated at the tyre/road contact based on the instrumentation of the tyre [1][2][3][4][5] or of the wheel [6][7][8]. The methods based on the instrumentation of the tyre normally require the placement of measurement sensors (accelerometers, optical sensors…) embedded in the interior thereof.…”

“…1 The forces and torques are obtained from signals measured by strain gauges bonded in the metallic part of the original wheels of the vehicle. Since the wheels of the vehicle are not replaced as in [6,7,[9][10][11], its dynamic behaviour is not significantly altered. The method proposed in this paper allows obtaining the forces and moments at any angular position of the wheel.…”

A mechanical approach of overload protection mechanism for a heavy truck wheel force transducer

“…The interaction between the vehicle and ground is represented by the forces, and therefore, sensing the wheel forces/torques is quite significant in vehicle testing field (Kadhim et al, 2011;Kuchler and Schrupp, 2001;Pavkovic et al, 2009;Pytka et al, 2011). To detect these forces, the famous multi-axis wheel force transducer (WFT) (Weiblen et al, 1999), which offers the capability of acquiring load data at the spindle of a vehicle, has been promoted extremely by researchers and engineers with great interests (Hong and Strumpfer, 2011;.…”

The inertial effect of acceleration fields on a self-decoupled wheel force transducer

“…The interaction between the tyre and ground is represented by these forces, and therefore, sensing the wheel forces/torque is quite significant in vehicle testing field (Iombriller and Canale, 2001;Mokhiamar and Abe, 2002;Pavkovic et al, 2009). To gain the time histories of these forces, the famous multi-axis wheel force transducer (WFT) which offers the capability of acquiring load data at the spindle of a vehicle, has been promoted extremely by researchers and engineers with great interests (Weiblen et al, 1999;Zhang et al, 2011;Lin et al, 2014).…”
