In the research of warm-up dummies at home and abroad, more than 100 experimental warm-up dummies have been produced. The development process of the warm-body dummy mainly goes through three stages. The first stage is the concept of clo, namely the thermal resistance of the clothing, proposed by the American scholars Gagge and research teams thereof in 1941, and the American military need climate research institute developed the first generation of warm-body dummies, which are single-stage warm-body dummies, and are used for testing the thermal resistance of the static clothing. Early thermal manikins generally served the military and only later gradually expanded to other areas, but currently thermal manikins remain important tools for testing military requirements. The second section is a sectional type warming dummy which is born in the 60 th of the 20 th century, and compared with a single-section warming dummy, the sectional type warming dummy has the advantages that each section can be independently controlled and independently heated, some simple postures of a human body are simulated, the temperature state of the body surface of the human body is more truly simulated, and the static and dynamic thermal resistance of clothes can be measured. The third generation of warm-body dummies was a sweating warm-body dummies, made in the 70 s of the 20 th century by Goldman in combination with professor mechells, etc. Compared with the first two generations of body warming dummy, the third generation of body warming dummy can simulate the temperature of the human epidermis more truly, and the measurement of the thermal resistance of the clothes is more accurate.
