Title Design of Mini-electromagnetic Safety Instruments in Fuze
Abstract
With the continuous development and progress of science and technology, military products manufacturing shows the trend of miniaturization, intelligent and modular. Electromagnetic safety instruments as an important component of fuze safety and arming (S & A) systems, on the premise of ensure its safety and reliability ,its miniaturization is now a hotspot, and given a lot of concern of scholars at home and abroad. Benefited from the development of micro-electromechanical system (MEMS) technology, which is a emerging technology and one of the hot spots of industry in the 21 century, its definition determines that this technology will have an important and far-reaching influence on the fuze safety and arming (S & A) system and micro-miniature safety instruments design . However, the current world manufacturing technology doesn’t have reached the standard of what it needs, the manufacture is very difficult,and the cost is very high. Therefore, under the traditional manufacturing technology, the electromagnetic safety instruments miniaturization is still a urgent problem to be solved in the field.
In this paper,I design and study about the micro-electromagnetic safety instruments, and work of the following aspects has already been solved:
1) According to the design requirements, put forward several feasible projects of electromagnetic safety instruments , and give on a brief introduction;
2) Design the solenoids with properties desired by electromagnetic safety instruments in fuze, and discuss the selection of materials and the winding structure
3) Derive the formulae of the distribution of magnetic fields generated by single solenoid; compare the results with stimulation results and data measured under laboratory conditions.
4）Calculate the electromagnetic force of the micro-electromagnetic safety instruments being made, and analyze the factors that affect the electromagnetic force.
Finally, summarize the work of this paper and propose recommendation for further reseach. 引信用微型电磁拔销器的设计:http://www.751com.cn/jixie/lunwen_78372.html
