Abstract: A triaxial force pin sensor array for measuring the actual forces generated in the footprint of a tire includes a high density of individual force pin sensors in a modular design that allows for rapid replacement of defective sensor array elements and substantially prevents dirt and contamination from affecting force measurements. The triaxial force pin sensor array further reduces electromagnetic interference (EMI) and radio frequency (RF) contamination of the sampled data signals. The triaxial force pin sensor array exhibits uniform response in the normal direction. Fz, regardless of contact location with individual triaxial force pins of the sensor array. Further, the triaxial force pin sensor array features mechanical overload protection.
