Modeling Dynamic Behavior of a Safety and Arming Mechanism
In the development of any new high explosive ammunition, often, the most intricate and problematic component is the fuzing system. Primary purpose of the fuze is to function with the bursting charge in a munition at a specified time and place. The fuze must include a Safety and Arming Device (SAD or S&A mechanism) to ensure that the ammunition may only switch into the armed state following exposure to firing forces and after reaching a safe distance from the muzzle. S&A mechanisms are often mechanical and operate using clockwork escapement mechanisms, similar to those found in wrist watches but in a less sophisticated manner.
