Abstract:

This investigation developed a workable computer simulation of the pin pallet runaway escapement which can provide the basis for the analysis and synthesis of various safing and arming devices. The dynamics of the various regimes of escapement motion are modelled. Coupled motion, impact, and free motion are considered. Sensing equations for the determination of the instantaneous positions of the pallet pin and the escape-wheel form the basis for the controls in the computer program. The simulation is applied to the timing of the mechanism of the M525 fuze with an assumption of constant input torque to the escape-wheel. The influence of changes on such parameters as escape-wheel torque, pallet moment of inertia, center distance, pallent radius, etc., are explored in detail by appropriate computer runs. Agreement has been found with existing experimental data. Finally, recommendations for continued work are given.
