| Abstract: | This paper comments several improtant points in the process of the vibrational environmental tests for the parts of military equipment. Mainly there are the dynamic content of the test, the influence of mounting method, the dynamic properties of fixtures and mounting resonance, the influence of dynamic properties of complex fixtures on the experiment and the ways to deal with it. As an example, the paper presents a method of mode modification used in predicting the influence of mounting on the dynamic properties of the fixture. |
