Abstract

The invention relates to an inertia measurement unit, in particular to a minisize embedded inertia measurement unit having the anti-high overload performance, which solves the problems of low installation accuracy and poor anti-overload performance of the existing inertia measurement unit. The minisize embedded inertia measurement unit having the anti-high overload performance comprises an installation body, three accelerometers and three spinning tops, wherein the installation body is an integrated structure; the installation body is provided with three concave platforms for accommodating the three accelerometers, three concave platforms for accommodating the three spinning tops, a hollow bus routing structure, a hollow outlet structure and a hollow embedment structure; the three accelerometers are respectively installed on the three concave platforms thereof, and the three spinning tops are respectively installed on the three concave platforms thereof. The invention effectively solves the problems of low installation accuracy and poor anti-overload performance of the existing inertia measurement unit, and is especially applicable to the guidance-function reconstruction and application of high-overload weapons such as cannonballs and the like.

Description

technical field [0001] The invention relates to an inertial measurement unit, in particular to a miniature embedded inertial measurement unit with high overload resistance performance. Background technique [0002] The inertial measurement unit is a navigation and guidance component widely used in the military field. The inertial measurement unit is generally composed of three accelerometers and three gyroscopes. In the installation, three accelerometers are required to be orthogonal to each other, and three gyroscopes are orthogonal to each other, and three accelerometers and three gyroscopes are required. The sensitive axes should be consistent with the directions of the X-axis, Y-axis and Z-axis in the coordinate system of the moving carrier respectively. The application in the military field not only requires the sensitive components of the inertial measurement unit (accelerometer and gyroscope) to have high installation accuracy, but also requires the inertial measurem...
