The invention discloses a laser test bench, which relates to the technical field of thermal explosiveness of energetic materials. The laser test bench comprises a laser fixing part and a reaction cavity, A laser collimating mirror is arranged on the laser fixing part, and the reaction cavity is arranged below the laser fixing part. The laser test bench is an integrated test device, the distance between the laser collimating mirror and a sample is kept fixed, and subsequent requirements can be met only by focusing once; even if an error occurs in production, processing, transportation and storage, the position of the laser collimating mirror can be freely adjusted within a certain range, so that the deviation is eliminated, and the trouble of re-focusing before each test is eliminated. Theinterior of the reaction cavity is coated with black frosted paint, so that risks caused by laser scattering or reflection can be avoided, and the overall safety of the reaction cavity can be improved. A sample pool is a consumable, the service life of the sample groove and the whole device can be prolonged; meanwhile, the proper sample pool can be independently machined according to the quality and the physical state of a tested sample, and convenience is brought to a test.
Description
technical field [0001] The invention relates to the technical field of thermal explosion of energetic materials, in particular to a laser test bench. Background technique [0002] It is increasingly important to study the thermal explosiveness of energetic materials when stimulated by laser light. Existing data show that there is no integrated device for studying the thermal explosion problem of energetic materials when stimulated by laser. At present, before conducting such experiments, it is necessary to calibrate the focal length of the laser, determine the laser aiming position, and then place the sample for the experiment, and this operation needs to be repeated before each experiment, which makes the experiment process cumbersome and time-consuming. Moreover, energetic materials are more dangerous under laser stimulation, and the scattered device layout makes such experiments have certain safety hazards. Therefore, it is necessary to develop a test device that is eas...
