[0110] For the deployment of the piezoelectric sensor array, based on the geometric shape of the tire blasting jet field and the axial symmetry of the pressure distribution, following the principle that "at any distance from the top of the cone, any busbar forms an 'isobaric circle' on the cross section perpendicular to the axis of the conical jet field", the sensors at different front and rear positions on the cone surface formed by the same busbar are cross-arranged on the truncated circles at different distances. This can avoid mutual interference between the front and rear sensors, reduce the interference of the sensor array on the jet free field, and perform a three-dimensional test on the pressure distribution characteristics of the jet free field, overcoming the disadvantage of arranging sensors on only one plane.
