Integrated device for in-situ static and dynamic force calibration

Abstract

The present invention discloses an integrated device for in-situ static and dynamic force calibration. The integrated device comprises a loading mechanism, a direction control mechanism, a force source control mechanism and an alignment and clamping mechanism; one end of the direction control mechanism is connected with the loading mechanism, and the other end of the direction control mechanism is fixed to one end of the force source control mechanism; and the alignment and clamping mechanism is connected with the other end of the force source control mechanism. With the integrated device adopted, the actual working condition of a system can be simulated in situ, and static force calibration or dynamic force calibration can be performed on the system under a condition that the working sensor of the system is not disassembled. According to the integrated device, the directivity of the excitation force of the integrated device is excellent, and the positions of the acting points of the excitation force of the integrated device are consistent; excitation of different force values can be applied, the magnitude of the excitation can be adjusted, and an exciting frequency range is wide; and a pressed component can be automatically aligned and clamped, and accurate alignment and limiting can be realized through using a vernier. The integrated device can be flexibly installed and used in a horizontal or vertical direction. The integrated device is compact in structure and is easy to operate.

Description

technical field [0001] The invention relates to the field of force value measuring equipment, in particular to an integrated device for in-situ static and dynamic force calibration. Background technique [0002] The calibration of the system is divided into static calibration and dynamic calibration. Domestic calibration research on test systems such as recoil and thrust is mostly limited to static calibration. The recoil force is actually a kind of dynamic force. For the dynamic force measurement system, if the "static calibration" method is adopted, the test system itself may have poor dynamic characteristics or there may be gaps between components, even if the static calibration accuracy is high, but There may also be large errors in the dynamic test, so that the entire test device loses its predetermined function under dynamic conditions, and it is very easy to cause human misjudgment. [0003] With the in-depth study of system calibration methods and the progress of m...
