This standard is applicable to strain gauge, piezoresistive and piezoelectric linear acceleration sensors, and the test error is 20%. Reference standards GB2298 Mechanical vibration and shock terminology GB/T13823.1 Calibration method of vibration and shock sensors Basic concepts GB/T13823.10 Calibration method of vibration and shock sensors Shock secondary calibration 3 Technical requirements 3.1 Test environment temperature The environment temperature for the transverse shock sensitivity test is 20±5℃. 3.2 Instruments and Equipment The instruments and equipment used for the lateral impact sensitivity test are the same as those used for the sensor impact primary calibration (see GB/T13823.10). In addition, a rigid fixture should be designed so that the sensor under test can rotate around its sensitive axis and be installed on the fixture at different angles to accept lateral impacts from different angles. The principle is shown in the figure below.

During the test, attention should be paid to eliminating the output caused by lateral impact. 5 Data processing The lateral impact sensitivity of the sensor is calculated using formula (1): S. ×100% Wu Zhong: A-the acceleration corresponding to the output of the sensor under test, m/s\; -the actual value of the selected impact pulse acceleration, m/s\. A wwW.bzxz.Net The test should give the maximum and minimum values of the lateral impact sensitivity and their corresponding angles, and mark the selected impact pulse waveform, acceleration and duration!
