Design And Research Of The Automatic Advanced Hydraulic Bracket In Compositive Area

The thesis raises designing the automatic advanced hydraulic bracket to support the terminal of the working fields according to the problems exposed to the supporting method nowadays being used in mechanized coal cutting. Considering the hydraulic bracket company has many maladies during the development of the products, The thesis raises adopting Virtual Prototyping to design the product. By simulation and modifying digital prototyping on computer before product, we can reduce the costs and shorten the design interval and improve the quality of the products. The theme also provides a successful paradigm for the design of other machinery products.The thesis introduces Virtual Prototyping technology, development of the hydraulic supports and the significance of designing automatic advanced bracket based on Virtual Prototyping technology. The thesis introduces the structure features of the bracket, the principle for enduring the load and instructs a method of counting key technology parameters using MATLAB to edit M files. The features and the fundamental circuit of the hydraulic controlling system are also instructed, and the hydraulic controlling system of the automatic advanced bracket is designed, putting forward the method of emulating based on the Virtual Prototyping technology. The thesis achieves three dimension design for the parts of the bracket, and completes virtual assemble using Bottom-Up assembly, checking irrational factors in the design, counting the quality, volume and the retary inertia of the assembly solid and creating engineering drawing from 3D model to 2D view in UG-NX. ".x_t" files of the 3D models are exported by Parasolid standard and make ready for the analysis using ANSYS software. The thesis instructs the principle for the FEA and solving steps, put forward the method of guiding the ".x_t" file into ANSYS conditions based on the investigation of the interface between the CAE technology and CAD technology, making analysis of stress and strain for the main loading parts (ef. upper beam, etc) of the automatic advanced bracket by meshing, loading-solving and postprocessing, and verifying the result of the design of the parts in loading conditions according to the strain.
