An analysis was made of acceleration response measurements of solid-propellant rocket motors in vibration testing at the Arnold Engineering Development Center. In this type of testing, an electrodynamic shaker is utilized to provide the desired oscillatory driving force, and a test fixture is required to adapt the motor to the shaker. Although a test fixture can contribute adverse effects on the rocket motor motions for some conditions in vibration testing, the results of the analysis indicate that large undesirable rocket motor acceleration responses may be measured and invalidly attributed to the test fixture used.
