2. Feasibility
With a good description of the test
problem, we propose a limited number of practical simulation tests
that can lead to an answer. But this proposal must be put to the test:
this is the feasibility of the simulation tests.
We must confirm that the tests can
physically be executed within the limits of the test equipment and
test pieces.
Adaptation to test procedures, test
pieces and the test equipment may be necessary to improve the procedure
and the
quality of the results (closed loop). It may even be necessary to
re-consider the problem definition.
Then meaningful and measurable results must be obtained.
Typical questions:
Is
the test configuration practically possible?
Does the test configuration simulate the wear mechanism
or frictional behavior of the application.
Are there meaningful and measurable characteristics:
wear, friction, temperature,...
It is a time consuming stage and generates few test results, but it is an essential stage when new products or new test procedures are investigated.
