Description

technical field [0001] The invention relates to the safety technology of small-caliber projectiles, in particular to a "sandwich" type MEMS safety system integration device and a method thereof. Background technique [0002] The micro-mechanical safety system widely used in small-caliber bullets mainly relies on high-precision machining technology to realize the processing and assembly of various sensitive components, but due to processing tolerances and errors in the assembly process cannot be avoided, the error magnitude reaches hundreds of microns . It is the main factor that seriously restricts the development of miniaturized fuze safety and release control. Consistency and yield are also susceptible to processing conditions, resulting in uneven product. Based on the above problems, the micro-electromechanical system MEMS security system for fuzes based on micro-nano processing technology with good consistency, extremely low processing errors and low assembly links has...

Problems solved by technology

[0003] After the MEMS safety system is released, the flameproof slider is displaced under the action of a huge centrifugal overload and hits the release limit mechanism of the safety system, which is very prone to "crashing" or "twisting". The detonation sequence cannot be completely aligned or damaged. This invention proposes a "sandwich" type MEMS safety system integration device and its method. Based on composite materials and silicon bases, buffer devices and buffer action areas are added to effectively solve the problem. the above problem
