Abstract

The invention discloses a device and a method for measuring the thermal dose of a target object in an explosion transient temperature field, and aims to overcome the defects that the conventional measuring device and method are susceptible to electromagnetic interference, complex in system, required to be assisted by electrical measurement equipment and insufficient in precision. The device is composed of a sealing shell, a heated panel, n3 heat conduction metal pipes, a heat insulation component 4 and n3 shape memory alloy springs. The shape memory alloy spring is made of one-way shape memory alloy. The thermal dose parameter in the thermal effect is quantitatively converted into the spring deformation by utilizing the thermal deformation characteristic of the shape memory alloy spring, so that rapid quantitative measurement of the explosion thermal effect is realized. The measuring device is simple in structure, low in cost, capable of being repeatedly used, high in anti-electromagnetic interference capacity, convenient in result post-processing and high in measuring precision, can be used for rapid quantitative measurement of the transient temperature field under different regional conditions, and provides a new reference choice for thermal dose measurement of the temperature field.

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...
