“…Researches have made multiple attempts to calculate the contact patch dynamically and they have reported various techniques for measuring it. The use of sensor equipment is one of them [11]. As an example of this category, Braghin, et al [12] utilized accelerometers putting inside the tire in order to determine the contact forces and patches features.…”

The maximum acceleration that can be achieved by the car is limited by two main factors of maximum torque in the drive wheels and the maximum traction force in the contact patch. The first factor depends on the performance of the engine and the transmission system in the drivetrain dynamics, and the second factor depends on the friction between the tire and the contact patch. The importance of investigating the contact patch is valuable from perspective of increasing traction efficiency to reducing fuel consumption. In this study, a novel method based on image processing techniques was utilized to dynamically measure contact patch. Then, contact patch was modeled by the Bat algorithm considering the load on the tire and inflation pressure. Finally, the model was evaluated visually and statistically. Coefficient of determination (R2) for this model was 0.95.

“…Obviously, this method is more simplified than the actual situation. The contact area of the tread in the static state can be effectively obtained by the thermal paper method footprint, paint method footprint, stress plate, and other methods [7]. With the increase of the mass of the load, the area of contact with the tire pavement also increases, but increased tire stress will lead to the opposite result [8].…”

A tire’s three-dimensional stress for pavement is an important cause of asphalt pavement disease. In order to study the contact stress distribution between the tire and the pavement under real conditions, a sensor that can measure the tri-axial stress synchronously is designed, and a complete measurement system is established. The variation trend and stress value of tri-axial stress under steady rolling of the tire were obtained, and the stress distribution characteristics were analyzed. The results show that the stress in the three directions near the tire shoulder is greater than that in the crown area, and the stress peak moves gradually from front to back with the rolling of the tire. Compared with the simplified simulation model, these results provides valuable suggestions for exploring the real tire-pavement interaction.

Investigation of Tri-Axial Stress Sensing and Measuring Technology for Tire-Pavement Contact Surface

et al. 2022

A tri-axial stress sensor was designed to measure contact stresses in the tire–pavement contact patch. The shape and size of the sensor surface were designed considering both the asphalt pavement texture and the tire pattern. The top-down cracking mechanism was also taken into account, and the sensor was placed at the vertical crack depth. Temperature drifts and zero drifts were compensated for. The sensor had high structural strength and met the sensing requirements of specialized heavy vehicles. In a preliminary study, three sensors were fabricated and calibrated in three directions. Simulated measurements were performed using a tire–pavement surface contact test bench. Signals from the L-shaped sensor region were obtained for the upper, middle, and lower parts of the tire, and preliminary stress distributions were determined at different positions on the contact surface. This study has laid a foundation for the design and construction of a more precise test system in the future.
