Flexible Multibody Simulation of a Medium Weight Shock Machine

EasyChair Preprint 13333

Abstract

Equipment mounted on warship vessels must be designed to withstand the accelerations caused by underwater explosions (UNDEX) without contact with the hull. Depending on the characteristics of the equipment, its shock endurance is validated on a different shock testing machine. This work studies the dynamic simulation of a shock test on a Medium Weight Shock Machine (MWSM) using multibody methods. The multibody simulation involves flexible bodies that deform under the action of shock (impact) forces. The flexibility is parameterized using the modal reduction technique by means of eigenmodes and static modes under the framework of the Floating Frame of Reference (FFR) method.

Keyphrases: Flexible multibody dynamics, MWSM, Shock test, impact dynamics
