Description
Technical Field
The invention belongs to the technical field of performance testing of electronic components, and particularly relates to a testing device for testing the measuring performance of a tilt sensor when acceleration exists along the axial direction of a tilting shaft and the mounting position has errors.
Background
A high-precision tilt sensor chip, such as a 3D-MEMS-based high-precision two-axis tilt sensor chip, needs to have a sensing element parallel to a measuring platform during measurement, and two sensor axes perpendicular to each other. When the tilt sensor is at rest, namely no acceleration acts in the lateral and vertical directions, only the gravity acceleration g acts on the tilt sensor, and the included angle between the gravity vertical axis and the sensitive axis of the acceleration sensor is the tilt angle.
The double-shaft tilt angle sensor is mainly applied to many fields of national defense construction and civil use, and relates to control, displacement rotation detection and tilt angle measurement, such as tank fire control systems, vehicle-mounted radars, bullet train speed detection and control and the like. In the detection process, the inclination angle of the detected surface needs to be measured absolutely, and the requirements are high precision, digitalization and quick response.
However, in the current stage, the detection of the sensor is mostly performed under a static or ultra-low rotation speed dynamic condition, and if the inclination angle (around the X axis) of the object to be measured is measured under the condition that the object to be measured has acceleration along the axial direction of the tilting axis or eccentrically rotates around the tilting axis, the acceleration along the X axis and the centrifugal acceleration generated during the eccentric rotation of the object to be measured interfere with the accuracy of the angle measurement of the inclination angle sensor, so that a large error is generated between the measured data and the actual data.
