Definition of the Relationship Between Clutch Facing on Vehicle and Bench Testing Using Reliability and DOE 2004-01-3257

There is a large variation in the results of the durability of friction facings in field applications and in most cases there is very little information about the conditions in which the vehicle operated and therefore it was decided to developed a test procedure capable of containing all the different conditions of a vehicle.
For this works statistical applications such as DOE (Experimental Design for Experiment) were used to help in planning and to obtain of equations of the tests results and Weibull curves for statistical analysis and comparison of failure mode.
By this mean, it was possible to determine a correlation of the results on wear between the bench test and mileage covered on vehicle up to total wear.
Therefore it is new possible to estimate the durability of friction facing on vehicles based on bench tests and also obtain knowledge about the behave of the material relative to energy and working temperature.
