門式纖維鋪放機(jī)構(gòu)的設(shè)計(jì)與研究
[Abstract]:With the development and utilization of the properties of composites, the molding technology is also widely studied. Filament winding and fiber placement are more advanced molding technology. The research on filament winding and fiber placement abroad is far earlier than that in China, and has been applied in aerospace, military, chemical and other fields. The domestic research on filament winding technology is relatively mature at present. The research of fiber placement technology is in the developing stage. Because the fiber laying technology originates from the filament winding technology and the fiber laying technology can avoid many shortcomings of the filament winding technology, many domestic research institutes are paying more attention to this technology. A gantry fiber laying machine is designed in this paper. It is mainly made up of gantry frame and fiber laying head. According to the existing laying theory, the fiber laying head is divided into ten separate modules to design separately. The ten modules are: gantry frame, belt mechanism, guide mechanism, cooling mechanism, assembly mechanism, compression mechanism, shear mechanism, retransmission mechanism, heating mechanism, pressure mechanism. In order to ensure the efficiency and simplicity of design, the width of the fiber bundle used in this paper is 10mm, the head of the fiber bundle is four bundles, and the two sides of the filament path are symmetrical arranged. The molding width of one placement can reach 46 mm. In addition, each mechanism is designed separately on the basis of realizing the basic function of laying the head. After the whole structure modeling is completed, the whole motion of the mechanism is analyzed on the platform of the motion simulation plug-in SolidWorks software. In the adjustment and detection of motion simulation, the interference is avoided, the relevant parameters of the key points are detected and the placement track is verified. Finally, this paper carries on the mechanical analysis to the hanging plate of the bearing part of the placement head, under the calculation of ANSYS software, can show the deformation and the stress concentration of the part during the working process, and has carried on the remodel processing to it.
