Effective Road Profile (ERP) Control is a relatively new simulator control strategy which shows a great deal of promise in reducing automotive suspension and structural testing times, thus shortening the product development cycle. The key to ERP is a linearly approximated tire model consisting of a characteristic stiffness of the spring elements within the model (K), characteristic damping coefficient of damper elements within the model, (C), and the tire modal mass (MMTM). The tire parameters can be purchased as a data set from MTS Systems Corporation for approximately $6000 US per tire. This thesis offers an alternate method of obtaining the tire characteristics. A rigid two-part frame was installed within the pit of a four-post road test simulator. This frame was assembled around one hydraulic actuator with the test tire secured above the actuator pan. The hydraulic actuator was then used to input a drive file into the tire to produce a tire response file. From that tire response file, radial displacement and radial force are required for tire characterization. The Tire Characterization tool within RPCRTM Pro was used to calculate K, C, and MMTM as defined above. (Abstract shortened by UMI.)Dept. of Mechanical, Automotive, and Materials Engineering.
