Abstract
The Force Limited Vibration approach was developed in the nineties to reduce the overtesting associated with conventional vibration testing of aerospace hardware. Several methods have been considered for the estimation of the force limits. Because of its numerous advantages, the semi-empirical method is the most widely used technique for deriving these force limits. The paper first presents the mathematical relations of the semi-empirical method. The so-called C2 constant is the only parameter of the method that cannot be obtained directly or from low-level preliminary runs. The paper thus continues with a detailed discussion on criteria normally used for selecting the C2 constant and on the range in which it is normally expected to fall. The next section of the paper discusses the advantages of force limiting over the more traditional response limiting for notching vibration input to space hardware.
