Abstract


The runaway escapement is a important part for fuze delay arming,over the years, some experts at home and abroad has done depty study in theoretical and high-speed photographic. The runaway escapement’s kinematic and dynamic analysis formula has been derived with a lot of assumptions, It has great benefit on the understanding in the physical concept and analysis, However, theoretical research and production practice a bit outdated, and some models too complex to solve specific problems in the calculation and it is difficult to operate. This paper mainly through virtual prototyping technology, the impact of escapement body vibration cycle of the various parameters were analyzed. The main contents are include as following aspects:(1) through the runaway escapement structure, work process analysis and geometric parameters in the design requirements , Obtains the organization structure drawing of the pallet and the escape wheels, Provide the design parameter for the runaway escapement ’s modelling and the simulation.(2) A systematic analysis of the domestic and foreign institutions on the cycle of vibration of the runaway escapement, At the same time base on analysis of fuze arming distance, Obtains the significance that the runaway escapement have no fixed vibration cycle and And use the experiment date to proved it.(3) Modeling the runaway escapement with the soft UG and carries on the simulation with ADAMS to its vibration process, Obtains the simulation step, the friction beteen pallet and pallet axis, moment of inertia, driving moment ,the gap beteen pallet and pallet and so on factors impact to the runaway escapement’s vibration cycle. Carries on the analysis to the result, thus provides some bases for the runaway escapement parameter design.
