The newly initiated Clemson Motorsports Engineering Program, housed in the Department of Mechanical Engineering, provides unique educational opportunities to our students combining classroom engineering education, research, and race team experience. Additionally, the research and service projects conducted provide valuable information to race teams and companies in the automotive industry as well as involving students in both applied technology development and fundamental engineering activities. This paper describes the current activities and structure of the program together with our view for future development.

An Investigation of the Pulse Steer Method for Determining Automobile Handling Qualities

1993-03-01

The use of pulse steering tests for assessment of handling qualities was investigated using a simulation of a comprehensive, nonlinear four wheel model of an automobile. Evaluations were conducted using frequency response functions of yaw rate and lateral acceleration obtained by FFT processing of the simulated response. In addition, as suggested by the work of Mimuro et al [1], four parameters (steady state yaw rate gain, yaw rate natural frequency and damping ratio, and lateral acceleration phase lag at 1 Hz) that characterize these response functions were also obtained by curve fitting techniques. The effects on accuracy of the response functions and the four parameters of variations in pulse shape, duration, and magnitude were investigated. Results from the simulated pulse steer test were compared with those from simulated swept sine steering tests.
