The wide-range acceleration transducer rapid calibration test stand can rapidly calibrate a wide-range acceleration transducer.

Description

technical field [0001] The invention relates to a test bench, more precisely, the invention relates to a rapid calibration test bench for a large-range acceleration sensor which can be used for quickly calibrating a large-range acceleration sensor. Background technique [0002] With the development of control technology and sensing technology in recent years, sensors have become more and more widely used in the industrial field. Among a wide variety of sensors, acceleration sensors are widely used. Aspects play an extremely important role and are widely used in navigation, measurement, and industrial control. [0003] The small-range acceleration sensor is mainly used for the measurement of the acceleration of less than 1g (gravity acceleration, 9.8m / s2) such as the measurement of the space attitude of the object. During the calibration process, the method of manufacturing the space angle can be used to conveniently carry out the static calibration within the range. The lar...

Problems solved by technology

The large-range acceleration sensor mainly measures vibration and object motion state, etc., and the measurement range is much larger than 1g. For this type of acceleration sensor, it is more troublesome to calibrate the entire range.

[0004] At present, the large-scale acceleration measurement methods and instruments or equipment at home and abroad are huge and expensive, or the calculation methods are complicated, and the experimental process is lengthy.

After searching patent documents, for example, Chinese patent announcement number CN10307983B, announcement date 2013.04.17, application number 201110302992.X, application date 2011.10.9, the applicant Xi'an Jiaotong University, the name is "a simple high-g value acceleration shock test bench ", although the test device described in the technical solution of this application has a simple structure and relatively low manufacturing cost, the method of obtaining the acceleration value according to the test data processing is very complicated, inconvenient to handle, and has a correlation with the physical properties of the materials used in the test bench components. Very strong, the stability is not good when mass-manufactured, and because the impact method is used for testing, it has a great impact on the service life of the test bench
