Abstract

The invention provides a suspension fiber flexibleness supporting structure which comprises a swing framework and a force moment coil, wherein the force moment coil is arranged on the swing framework in a winding mode and limited by clamping plates. Suspension fibers are arranged at two sides of the upper end of the swing framework. One end of each suspension fiber is fixedly connected with the force moment coil. The other end of each suspension fiber penetrates an insulating tube and then is respectively welded with a suspension fiber post and an adjustable suspension fiber post to form a whole. The suspension fiber post is connected with a base of an accelerometer in a cementing mode to form a whole. A vortex vane is arranged at one side of the swing framework. The suspension fiber flexibleness supporting structure has the advantages of being easy to process and assemble, high in reliability, low in cost, capable of achieving volume production, good in practicality, easy to popularize and apply and big in practical value.

Description

technical field [0001] The invention relates to a flexible support structure of an accelerometer, in particular to a torque device flexible support of a high-precision inertial accelerometer. Background technique [0002] The flexible accelerometer uses elastic materials to make the flexible supporting structure. The commonly used flexible supporting structures are all in the form of flexible rods or quartz plates. The contradiction of precision is difficult to solve, especially the support in the form of quartz is brittle, and the reliability of vibration and shock resistance is not high. At the same time, the shape of the flexible rod and the quartz plate is special, and the processing is difficult. Special equipment and special technology are required, and the yield is low and the cost is high. , so it is necessary to improve. Contents of the invention [0003] In order to solve the problem that the input range and the minimum sensitive quantity of the existing structu...
