  • Method of designing a fixture for a vibration testing system and a vibration testing system having the test fixture
    Patent number: 11774319
    Abstract: A method of designing a test fixture configured to mount to a vibration slip table and fix a test article to the vibration slip table during a vibration test includes performing finite element analysis using one or more boundary conditions determined from parameters of the vibration slip table, the test article, or the vibration test to optimize a topology of the test fixture, and outputting a geometric model of the test fixture having the optimized topology. Another method of designing a test fixture includes inputting the one or more boundary conditions into a topology optimizing solver. A vibration test system includes a test fixture designed according to the method.
