摘要:
针对现有的MEMS惯性开关万向性能较差,无法满足引信在大着角情况下可靠作用要求的问题,提出了基于动电极翻转的MEMS万向惯性开关。该开关采用周向分布弹簧支撑可翻转一定角度的圆形动电极,开关盖板为固定电极。由于动电极质心高于弹簧质心,在引信大着角撞击目标时,惯性力的分量会产生翻转力矩,使得动电极能够翻转一定角度与固定电极接触,增大了惯性开关的响应角度。仿真和试验结果表明,采用该结构惯性开关的响应角度能够达到120°。为引信实现大着角情况下的可靠响应提供设计参考。
Abstract:
Aiming at the problem that the present MEMS omnidirectional inertia switch is poor in omnidirectional performance and can not meet the requirement of reliability of fuze under the condition of large shooting angle, this paper provided an MEMS omnidirectional inertia switch based on moving electrodeove overturning; the switch adopted structure that a round moving electrode which could overturn for a certain angle, which was supported by a spring distributed in the circumferential direction, and a fixed electrode was arranged on a cover plate of the switch. The barycenter of the moving electrode was greater than that of the spring, so that when the fuze hits against a impact at large shooting angle, the component of inertia force could generate turning torque, then the moving electrode overturned for a certain angle to contact with the fixed electrode, and the response angle of the inertia switch was enlarged. Simulation and test results showed that the response angle of an inertia switch adopting the structure could reach to 120 degrees.
