Abstract

The invention relates to an ultra-caliber launching overload testing method and system. The testing system comprises an acceleration sensor, a data line, a distance control line, a free end of a pluggable joint, a fixed end of the pluggable joint, a base, a data acquisition card, a USB (universal serial bus) cable and a computer, wherein the acceleration sensor arranged in an object to be launched is used for detecting launching overload, the data line with the pluggable joint is used for transmitting launching overload data, and the data is stored in the external computer. The ultra-caliber launching overload testing method has the characteristics that measuring result is accurate and direct, a launching system does not need to be destructively modified, and an internal space of the object to be launched is basically not occupied and an external ballistics process of the object to be launched is not influenced.

Description

technical field [0001] The invention belongs to the field of super-aperture launch overload testing, and in particular relates to a test method and a test system for super-aperture launch overload. Background technique [0002] The commonly used launch overload test methods mainly include the missile-borne accelerometer measurement method, which can directly measure the launch overload. This method has the following disadvantages: [0003] 1. The missile-borne test system integrates the acceleration sensor, AD converter, memory, power supply, etc., and places it in the ejected object. The integrated missile-borne test system has a complex structure and a large volume, and requires Making larger modifications to the ejected object is only applicable to larger caliber launch systems, and cannot be used for small caliber launch systems. [0004] 2. Due to the limitation of the volume of the ejected object, the integrated missile-borne test system mostly uses small sensors, AD ...
