Construction analysis and design methodology of polymer parts of laser head housings

The issue of designing polymer parts of the laser head body is being considered in order to ensure its compactness and taking into account the capabilities of additive equipment. The manufacture of such a laser head housing from plastic makes it possible to reduce its material consumption compared to a housing made of aluminum alloy, and it is also proposed to further reduce the material consumption of the plastic housing by introducing special samples and stiffeners into its design. Using the CAE module of the CAD/CAM system of SolidWorks, a comparative analysis of the strength and rigidity of the body parts design options has been carried out before and after their modification; the results demonstrate the possibility to replace the material of the body parts from aluminum alloy to plastic and show that reducing the material consumption and changing the design of the body and its parts does not lead to a loss of its strength and the stiffness, and does not affect the laser head operation. Based on the analysis of the design of polymer parts of laser head housings made on a 3D printer, measures to eliminate the identified deficiencies and the requirement to preserve the optical circuit, a design methodology for nuclear heads is developed.
