Abstract

Abstract: Based on the potential flow theory, the boundary element model of the missile is built and the variation of the added masses, induced by both rigid body motion and the elastic vibration, are studied. Besides, the influences of added mass on slamming force and kinematic equation of structure are also investigated. Through calculation, not only the mass matrix but also the damping coefficient of the system will be affected.

Key words
