In order to improve the firing dispersion of the Shipborn Multiple Launch Rocket Systems ( SMLRS) , the vibration characteristics and vibration control of the SMLRS are studied using the transfer matrix method for multibody system and independent modal space control method. The dynamic modal of a SMLRS and the method for numerical calculation and control of vibration performance of the system are developed. The features of this method are as follows,without the global dynamics equations of system,high programming,low order of matrix involved and high computational speed. The rapid calculation and vibration control of the dynamic properties of a SMLRS under various loading conditions is realized and the numerical results are verified by the modal test. The propositional method is important to control vibration to improve firing dispersion of SMLRS.
