Embodiment Construction
[0026] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0027] The acceleration test device of the present invention includes a four-point turning mechanism 1, a heat insulation transfer structure 2, and a mounting platform body 3, and each of the heat insulation transfer structure 2 and the mounting platform body 3 is two. On both sides of the four-point overturning mechanism 1, the heat-insulating transfer structure 2 and the mounting platform body 3 are sequentially fixed and installed.
[0028] The four-point turning mechanism 1 is a long and narrow structure with four supporting beams and two mounting planes, and is mainly used to realize the four-point turning test of the accelerometer within the range of 360° in the circumferential direction. It achieves the flatness control requirements of each surface through the boss structure at the contact point between the installation surface and th...

The invention discloses an accelerometer testing device. The accelerometer testing device comprises a four-point turnover mechanism (1), heat insulation switching structures (2) and mounting table bodies (3), and the number of the heat insulation switching structures (2) and the number of the mounting table bodies (3) are two. The two heat insulation switching structures (2) and the two mounting table bodies (3) are fixedly mounted on the turnover mechanism mounting planes (11) on the two sides of the four-point turnover mechanism (1) in sequence. The four-point turnover mechanism (1) comprises two turnover mechanism installation planes (11) which are the same in shape and size, are rectangular or square and are connected through a supporting beam (13). 16 boss structures (12) are arrangedat eight right angles of the two turnover mechanism mounting planes (11) in the same extending direction as the turnover mechanism mounting planes (11), and form a reference plane for realizing four-point turnover in the four-point turnover mechanism (1). The device has the characteristics of simple structure, easiness in operation, small occupied area, high efficiency, low cost and the like.
Description
technical field [0001] The invention belongs to the technical field of accelerometers, and in particular relates to an accelerometer testing device. Background technique [0002] The quartz flexible accelerometer mainly uses the force feedback principle to obtain a current proportional to the input acceleration, and obtains the input acceleration information by sampling the current. As an inertial instrument, the performance of the quartz flexible accelerometer is characterized by the calibration of its model equation coefficients. Four-point method, eight-point method, twelve-point method, etc. can be used to test the coefficients of the accelerometer model equation. The most commonly used method is the four-point method, that is, within the range of 360° in the circumferential direction, 4 points are equally divided, one for every 90° Points, real-time output of the accelerometer at each position is realized through the test equipment and tooling, and the output value of ...
