Motorcycle Secondary Drive Testing using a Servo-Hydraulic Laboratory Test System

This paper documents the process used to correlate the secondary belt degradation experienced on the test track with the secondary belt degradation experienced during laboratory tests using a Secondary Drive Test System. Two different software products were used to produce this correlation: nCode's pseudo-damage functionality was used to estimate the proportional belt degradation and MTS's RPC Pro functionality was used to edit the field data, create a time history file, and to shift the frequency domain of the vehicle into the usable range of the servo-hydraulic actuator (time stretching).

For purposes of this paper, the test data and information presented in this paper is based on two different secondary drive belts that were used on the test track as well as in the laboratory tests. As will be shown, the plot information that resulted from these tests showed very good correlation.
