Multibody Dynamic Analysis of a Safeing and Arming Device

ADAMS models were created and analyzed to determine the arming time for several design concepts for a safeing and arming device on a complex weapon system. The device functions as a safety mechanism, allowing certain parts to move only when the entire system is spun at a very high rate.

The key aspects of the ADAMS models were the part geometries, masses, spring stiffnesses, and initial configurations. The ADAMS models tracked the many impact and friction loads developed between the parts of the device when subjected to varying initial spin conditions.
