Abstract

According to a shock wave single-body multi-sensor array testing method and device, shock waves can be tested from multiple angles, the overpressure value and the explosion center position of the shock waves can be estimated through a single testing device, the arrangement speed of a shock wave testing site is increased, and the shock wave testing precision is improved. According to the shock wavesingle-body multi-sensor array testing method, the shock wave propagation has directivity, the shock wave overpressure value in the direction opposite to the center of explosion is the maximum, and when the overpressure sensor is not opposite to the center of explosion, the overpressure values acting on the overpressure sensor are different according to different incident angles; and the incidentangle and the front pressure are modeled according to the data values acquired by the plurality of overpressure sensors with different angles to estimate the incident direction of the shock wave andthe shock wave overpressure value of the current distance point.

Description

Technical field [0001] The present invention belongs to the technical field of impact wave test, and more particularly to an impact wave monomer multi-sensor array test method, and an impact wave mean multi-sensor array test device. Background technique [0002] In dynamic impact wave test scenarios, due to the position of the burst, it may cause the sensor to be inserted during the prediction of the test results. [0003] The traditional solution uses the sensor array technology, like a matrix type, circular, etc., to ensure the accuracy of the test results. [0004] However, due to the uncertainty of the burst, the technical solution requires a large number of test nodes and test sensors to obtain relatively accurate results, and the sensor sensitive surface cannot be aligned, so that the results of the test result are relatively large. Inventive content [0005] In order to overcome the deficiencies of the prior art, the technical problem to be solved by the present invention...
