Embodiment Construction

[0038] The technical solutions of the present invention are further illustrated by the drawings and specific embodiments of the specification:

[0039] like figure 1 As shown, the warm body dummy in accordance with one embodiment of the present invention has an external contour that simulates the live-person, and is divided into 14 blocks (parts), that is, head 101, torso 102, left arms 103, left arm 104, left hand 105, the right arm 106, the right arm 107, the right hand 108, left thigh 109, left calf 110, left foot 111, right thigh 112, right calf 113, right foot 114.

[0040] The above 14 parts of the fake person (combined together) are commercially available.

[0041] like figure 1 As shown, as an example, the above-described 14 parts of the fake person may have a connection method in which a metal column is inserted at the bottom of the head 101, directly inserted into the upper end of the torso 102; a bolted connection between the left brach arm 103 and the torso 102; A bolt...

Abstract

The invention provides a warm dummy for an environment thermal comfort experiment. The warm dummy is characterized in that 16 electric heating sheets which are reasonably designed and can be produced in batches are adopted, so that compared with a traditional method that heating wires are directly wound on a dummy model manually, the manufacturing efficiency is greatly improved, and the cost is saved; the thickness, width and spacing of the electric heating wire of the heating sheet are uniformly designed according to the heat flux density requirements of each part, and the heating sheet is processed and generated at one time by adopting a copper sheet chemical etching method, so that the problem that the manufacturing precision is difficult to comprehensively guarantee in a traditional manual heating wire laying mode can be avoided; each heating sheet is obtained by utilizing a model curved surface unfolding method, and by virtue of a double-sided heat-conducting adhesive film, the good fitting property of the heating sheets and the surface of the dummy is ensured; the electric heating wire of the heating sheet adopts a corrugated design, so that the heating sheet has certain ductility; the input voltage of the electric heating wire is 24V and is within the safe voltage range of a human body; and the heating sheet adopts a three-layer film type structure.

Description

Technical field [0001] The present invention relates to a warm body fake person for ambient thermal comfort experiment. Background technique [0002] Whether it is aircraft, automotive, ship, etc., or carrier, submarine and other scientific research or military transportation tools, the internal thermal environment is an important factor affecting members' survival. In order to ensure that the occupants can effectively implement the assigned tasks in the transportation activities, it is first to ensure that the transportation tool can provide a suitable artificial environment (air ingredient, temperature, pressure, humidity, etc.). Therefore, the above-mentioned artificial environment is necessary to carry out the necessary environmental tests before investing in normal use, and the thermal environmental test needs to be used to replace the real human thermal load simulation. [0003] In the prior art, the warm body fake people typically use a method of winding the heating wire t...
