Wearable body-warming dummy and clothing thermal resistance measuring method

Abstract

The invention belongs to the field of garments, and provides a wearable body-warming dummy and a clothing thermal resistance measuring method; the body-warming dummy comprises a body-warming dummy body, and the body-warming dummy body is hollow inside and is soft and wearable; the body warming dummy body is composed of a plurality of heating subareas which can be independently heated, every two adjacent heating subareas are detachably connected, and the surface temperatures of the heating subareas are respectively set according to the distribution characteristics of the surface temperature ofa human body. The thermal resistance measuring cost of clothes can be greatly reduced, the problems that the overall structure is heavy and inconvenient to move due to the fact that the thermal dummyis made of copper or aluminum or other materials are solved, and the surface temperature of the heating subarea is set according to the distribution characteristic of the surface temperature of a realhuman body. The clothing thermal resistance measurement result is more consistent with the wearing characteristics of a real human body, so that an important reference value is provided for clothingcomfort research and heat retention property test.

Description

Technical field[0001]The invention relates to the field of clothing, in particular to a wearable thermal dummy and a method for measuring thermal resistance of clothing.Background technique[0002]In domestic and foreign research on warm-body manikins, more than 100 kinds of experimental warm-body manikins have been produced. The development process of the body warmer has mainly gone through three stages. The first stage was the "clo" concept proposed by the American scholar Gagge and his research team in 1941, which is the concept of thermal resistance of clothing. The U.S. Munitions and Climate Research Institute developed the first-generation thermal manikin, which is a single-stage thermal body. Dummy, used to test the thermal resistance of static clothing. In the early days, the warm-body mannequins generally served the military, and later they gradually expanded to other fields, but the warm-body mannequins are still an important tool for testing munitions. The second price segm...

AI Technical Summary

Problems solved by technology

[0004] However, since the vast majority of thermal dummies are made of materials such as copper or aluminum, there are problems such as high cost, heavy overall structure, and inconvenient movement.
