Abstract:

In this paper, a new algorithm of parameters of frictional surface is introduced, which is based on the least square method middle line. By ap- plying a microcomputer to the outline instrument, a lot of surace parameters are intelligently measured. By comparison with the measurement of the prototype and through the checking computation of record curves, this method is satisfactory.
