Performance Evaluation of the UMTRI (University of Michigan Transportation Research Institute) Tire/Wheel Uniformity Test Machine

摘要

One outgrowth of UMTRI's Truck Tire/Wheel Systems Research Program has been recognition of the need for a truck tire uniformity test machine capable of measurements to at least 50 Hz. This report provides an overview of the design and initial testing of a prototype machine recently constructed at UMTRI for this purpose. The machine utilizes a drum that is 67.23 inches in diameter, driven by an electric motor capable of speeds from 0 to 60 MPH. The face of the drum is 24 inches wide so that dual wheel assemblies can be tested. It accepts complete truck tire/wheel assemblies, making it possible to test tires, wheels, and hub components in single and dual wheel configurations.
