Stabilizing device used for fixing detonation pressure sensor and installation method thereof

Abstract

The present invention discloses a stabilizing device used for fixing a detonation pressure sensor. The stabilizing device comprises a detonation pressure sensor stabilizer and a coaxial cable stabilizer, and the detonation pressure sensor stabilizer is a cylinder equipped with the large and small diameter stepped center holes matching an outer circle of a detonation pressure sensor body. The outer cylindrical surface of a circle body is equipped with the outer screw threads, and the end head is equipped with a concave edge bench. The large diameter center hole is equipped with the inner screw threads, and the outer cylindrical surface corresponding to the middle part of the large diameter center hole is symmetrically equipped with the installing holes communicated with the large diameter center hole. The coaxial cable stabilizer is a stepped cylinder equipped with an internal center hole and the external small, medium and large diameters, wherein the outer cylindrical surface of a small diameter cylinder is equipped with the outer screw threads, the end face is equipped with a counter bore communicated with the center hole. According to the present invention, the measurement data deviation caused by the instability of the sensor and a measurement error caused by the swinging or loosening of a coaxial cable are avoided effectively, thereby guaranteeing the accurate measurement of the detonation pressure sensor to a detonation wave.

Description

technical field [0001] The invention relates to the fields of explosion mechanics and weapon science, in particular to a device for improving the accuracy of data collection by using a detonation pressure sensor stabilizer and a coaxial cable stabilizer. Background technique [0002] Pressure is the most basic physical quantity that characterizes the state of matter, and it is closely related to natural phenomena, weapon tests, industrial production, and even people's daily production and life. In nature, from the absolute vacuum state of cosmic space to the detonation shock wave produced by the explosion of nuclear material produced by nuclear explosions, etc., the pressure range covers about 30 ranges. According to the international measurement standards, the pressure is divided into low pressure (1~10Pa), medium pressure (103~104Pa), high pressure (>106Pa), ultra-high pressure (>108Pa), etc. For the measurement of pressure, in our country, especially in the fields ...
