Abstract

The invention discloses a thermal dose measuring device and a measuring method of a target object in an explosion transient temperature field, and aims to solve the shortcomings of the existing measuring device and method, which are susceptible to electromagnetic interference, complicated in system, needing the assistance of electric measuring equipment, and insufficient in precision . The device consists of a sealed shell, a heating panel, n 3 Root heat-conducting metal pipes, heat-insulating components 4, n 3 Root shape memory alloy spring composition. The shape memory alloy spring is made of one-way shape memory alloy. The invention utilizes the thermal deformation characteristics of the shape memory alloy spring to quantitatively convert the thermal dose parameter in the thermal effect into the spring deformation, and realizes rapid quantitative measurement of the thermal effect of the explosion. The measuring device has the advantages of simple structure, low cost, reusability, strong anti-electromagnetic interference ability, convenient post-processing of results, high measurement accuracy, and can be used for rapid and quantitative measurement of transient temperature fields under different geographical conditions, providing a basis for thermal dose measurement of temperature fields. A new reference option.

Description

technical field [0001] The invention belongs to the field of temperature detection and relates to a device for measuring the heat of an object target in a transient temperature field. More specifically, it relates to a measuring device for detecting the thermal dose of an object target in an explosion temperature field by utilizing the thermal deformation characteristics of a memory alloy spring. Background technique [0002] The damage effects of conventional explosive explosion mainly include shock wave overpressure, explosion products and thermal effects. At present, the focus of domestic and foreign research on condensed phase explosives is the shock wave damage effect and fragment damage, but there are few studies on the thermal radiation effect of high energy condensed phase explosives after explosion. The reasons for this phenomenon are as follows: one is that the effective range of the shock wave is larger than the distance of the thermal radiation; the other is tha...
