Vibration Analysis Reduces Computer TimeImproved calculation method promises to reduce computer time by factor of 10 for vibration analysis of complex structures. Method originally developed to predict mechanical response of spacecraft to maneuvers in various cases in which same booster is used with different payloads. Method is more exact than conventional normal-mode methods; it involves no initial approximations of assumptions. Calculation cost is reduced without loss of accuracy.
