Description
The objective of this project is to design a device to collect data on the mechanical properties of bicycle tires with the goal of validating Rotta's 2D model and enhancing the current bicycle model. In validating Rotta’s 2D model, a better understanding of how bicycle tires behave will be achieved. This study will also take into account different parameters, such as tire size and construction methods. In addition, the data collected will enhance the current bicycle model and show how tire behavior influences bicycle stability and handling. By analyzing the combination of these two models, optimal tire design will be facilitated.
Six constraints govern the device’s design: accept tires with a 5-inch width and rims with a diameter up to 29 inches, prevent wheel rotation about any axis, allow vertical and lateral movement, apply a vertical load to the wheel, measure vertical displacement and lateral force, and simulate various camber angles. The device uses a parallelogram design connecting the frame and fork together, thus allowing for vertical and lateral movement of the wheel but preventing rotation around any axis. At the base of the frame, a steel plate will be mounted on a hinge and rest on a brace. This hinge will allow the plate to tilt, simulating the wheel at various camber angles. The device will collect data using various PASCO force sensors, and the data will be compiled using DataStudio.
