System and method for testing thermal resistance of life jacket in water

Abstract

The invention relates to a system and a method for testing thermal resistance of a life jacket in water. The system comprises a thermal dummy used for supplying heat to the life jacket; the simulated water environment test box is used for providing a real sea area environment for the thermal manikin; the water flow internal circulation water pump is used for simulating the actual seawater circulation flow state; the heat flux density and temperature measuring system is used for detecting the heat flux transferred outwards from the skin surface of the thermal dummy and measuring the temperature inside and outside the life jacket; the data acquisition system is used for acquiring the heat flow and the temperature inside and outside the life jacket; the LabVIEW data detection and analysis system is used for outputting the thermal resistance value of the life jacket according to the received heat flow and the temperature inside and outside the life jacket; and the temperature sensor is used for monitoring and setting the core temperature of the thermal manikin and the skin area of each part. According to the invention, thermal resistance test can be carried out in water, the test result is more in line with real human wearing characteristics, and the accuracy of the thermal resistance measurement result is improved.

Description

technical field [0001] The invention relates to the technical field of wearable equipment and thermal resistance testing, in particular to a testing system and method for thermal resistance of underwater life jackets. Background technique [0002] Life jackets are important life-saving equipment for ships in distress at sea and aircraft wading accidents. Loss of temperature in cold water poses a serious threat to the life safety of people falling into the water. Life jackets are one of the main guarantees for the safety of people falling into the water. Accurately assessing the thermal protection performance of life jackets and protecting those who fall into the water from low temperature cold shock is an important research direction in the field of water emergency rescue equipment. [0003] Thermal insulation of clothing is an important physical index for evaluating thermal comfort and thermal safety in extreme environments. " and GB / T 18398-2001 "Test method for thermal ...
