Project in model analysis

  1. Jan 9, 2009 #1
    I am doing project in model analysis.
    could any explain that, why should we find the values of natural frequency and mode shapes for any structures?
    Particularly for space vehicles for natural frequency and mode shapes.
    If we find the values of natural frequency and modeshpaes, what could we predict in future???

    Plz send the answers who reads this question???

    Natural frequency is used in differential equations describing structural vibration motion. Therefore, you need natural frequency to evaluate structure dynamic displacement response due to time-varying loading. You need the mode shapes to see how the structure is dynamically displacing. You need the dynamic deflections to evaluate the dynamic stress on the structural components.
