Embodiment Construction

[0038] Refer to the attached Figure 1~16 , the present invention will be described in detail in conjunction with specific embodiments.

[0039] A time-varying radiation heat flow experimental system based on distance control, including a radiation source, a radiation source load-bearing frame, a radiation source mobile support, a radiation source controller, a controller, a driver, a DC power supply and a test bench base.

[0040] The base of the experimental table is used to fix the entire experimental device and the mobile bracket of the radiation source to prevent the device from falling. The base of the test bench is made of solid 304 stainless steel, and the base of the test bench is L-shaped as a whole to improve the stability of the bottom of the entire experimental device. It can be seen from the figure that the base of the test bench has a longitudinal support and a platform of the base of the test bench. The bottom horizontal plane of the base of the test bench has a...

Abstract

The invention discloses a time-varying radiation heat flow experiment system and measurement method based on distance control, and relates to an experiment device and a test system capable of realizing time-varying radiation heat flow (time-varying heat flow). The experiment system comprises a radiation source, a radiation source bearing frame, a radiation source moving bracket, a radiation sourcecontroller, a controller, a driver, a direct-current power supply and an experiment table base. The radiation source moving bracket adopts a guide rail sliding table. A guide rail sliding block is arranged on the guide rail sliding table. A radiation source bearing frame is installed on the guide rail sliding block, and a radiation source is fixedly installed below the radiation source bearing frame. A fixing frame is installed on the lower portion of the guide rail sliding block, a baffle rotating rod is installed on the fixing frame through a bolt, the baffle rotating rod is fixedly connected with a baffle, the baffle is located under the radiation source, and the motor is installed above the guide rail sliding table and drives the lead screw to rotate. The controller and the direct-current power supply are respectively connected with the driver, and the driver is connected with the motor. The direct-current power supply provides power for the motor. The radiation source controlleris connected with the radiation source.

Description

technical field [0001] The invention relates to a time-varying radiation heat flow experimental system and measurement method based on distance control, which relates to an experimental device and a test system that can realize time-varying radiation heat flow (time-varying heat flow), especially an An experimental system and a measurement method for realizing radiant heat flow varying with time. Background technique [0002] Solid combustibles include natural and synthetic materials. In particular, synthetic materials such as polymers have been widely used in national production and life because of their good physical and chemical properties. Such as sea, land and air transportation, medical materials, building decoration, aerospace instruments and equipment, industrial devices and recreational devices, etc., are important materials in the fields of industry, agriculture, national defense and science and technology. However, solid combustibles are prone to pyrolysis and c...
