Embodiment

[0022] Embodiment: The measuring ranges of four groups of micro accelerometer units are 10g, 100g, 500g and 10000g respectively. In order to maximize the performance of the device and reduce the difficulty of design and processing, the mass block of each unit in the array is equal to the thickness of the fixed beam. The widths of the fixed beams in the 10g, 100g, 500g and 10000g micro-acceleration units are 80um, 100um, 190um, and 700um, respectively, and the lengths of the fixed beams are 650um, 650um, 500um, and 500um, respectively.

Abstract

This invention relates to one micro speeder for normal bullet process anti-high load compound meter, which comprises four sets of micro speeder units, wherein, the units are set by two times two array; two above rows pressure sensitive resistance is set along beam length direction; down two sets of micro speeders pressure resistance along fix beam width direction; each micro speeder unit frame is of one integral one.

Description

technical field [0001] The invention relates to a micro-accelerometer, in particular to a compound micro-accelerometer for conventional ammunition guidance and anti-high overload. Background technique [0002] Modern warfare is a high-tech competition. In order to meet the requirements of modern warfare, the strike accuracy of weapon systems and the utilization efficiency of ammunition are all required to be very high. "Forget after launch" and "Transfer after launch" improve the survivability of one's own side on the battlefield. At the same time, in the modern world and political environment, it is critical to strike targets while minimizing collateral damage to friendly forces and civilians. Therefore, the sharp increase in the proportion of precision-guided weapons used in warfare has become an inevitable trend of the times. It is not only a product of the new military technology revolution, but also leading the main theme of the future high-tech battlefield. Conventio...
