Problems solved by technology

The traditional measurement methods for the amount of rotation include gyroscopes and rotary encoders. The traditional measurement method can only obtain one of the three types of rotation, and the other two are obtained through calculation. Errors will inevitably occur in the calculation and affect the accuracy.

Abstract

Disclosed is an acceleration measurement based three-dimensional rotation momentum test device and method. The device comprises a hollow shell, four rectangular coordinate type brackets respectively adhered to the interior of the hollow shell and located at four non-coplanar points and accelerometers adhered to bracket centers and with testing directions respectively parallel to x, y and z directions. The entire test device serving as the hollow shell is adhered to a to-be-tested rotation object, the accelerometers are used for testing three-dimensional rotation momentum of the to-be-tested object, angular speed and angular acceleration can be directly acquired from test results of the accelerometers, and angular displacement can be acquired through indirect integral of angular speed combined angular acceleration.

Description

technical field [0001] The invention relates to the technical field of three-dimensional rotation amount testing, in particular to a three-dimensional rotation amount testing device and testing method based on acceleration measurement. Background technique [0002] The measurement of the amount of rotation is ubiquitous in human life. The so-called amount of rotation is angular displacement, angular velocity and angular acceleration. The traditional measurement methods for the amount of rotation include gyroscopes and rotary encoders. Traditional measurement methods can only obtain one of the three types of rotation, and the other two are obtained through calculation. Errors will inevitably occur in the calculation and affect the accuracy. Moreover, occasions that need to measure the amount of rotation, such as mobile phones, aerospace, ships, etc., also need to measure the amount of motion (acceleration, speed, and displacement). The method of measuring the amount of motion...
