b) Set the Fixture Force Limits to ±1000 N.
4. Set Specimen Force Limits.
a) Calculate the Specimen Force Limits.
For this example test, the beige spring has a capacity of 0 N and -4050 N. While you could use
these values for a specimen limits, it makes more sense to set the specimen limits just outside our
expected tuning and testing values in order to stop the test quickly if something unexpected happens.
The tuning procedure uses forces from - 50 N to -150 N and the testing procedure uses forces from
0 N to -200 N. As a result, specimen limits of +50 N to -250 N provide protection just outside the
limits of the tuning and testing procedures.
b) Set the Specimen Force Limits to +50 N and -250 N.
