Research And Development On The Design Software Of Hydraulic Support

Hydraulic supports are the key equipments on the fully mechanized coal face of mechanization in coal mine, and their performance can directly influence the safe production and productive efficiency. Because of the diversity of geological structure and coal seam occurrence condition, the hydraulic supports products have a strong specificity on structural features and technical parameters, and the production features are single set and low-volume model, the design work during the product forming process accounts for a larger proportion. Utilizing the advanced design technology to design the professional design software is the most effective way to improve the product design quality and work efficiency.Based on the analyzing of domestic hydraulic supports design level, this paper utilized Visual Basic environment as the platform and developed the hydraulic supports design software. It included performance and structure analyzing modules, the performance analyzing module can complete the analyses calculation of supports kinematics, statics and capacity,the whole process conducts with human-computer interaction,and the result data can feedback to the engineering technology persons using the report and graphic forms; during the development of structure analyzing module, this paper introduced the parameters design thought, and combined the parameters design with finite element analysis in designing the structure, this realized the structure parameters design and finite element analysis calculation. The realization of this method is applied by parameters design language (APDL) and VB object oriented programming technology to secondly develop and encapsulate the finite element software, the concrete implementation is using APDL to compile command procedure with parameters which included model establishment, mesh generation, load application and other finite element analysis processes; developing user operation interface by using VB object oriented programming technology, using function of VB text read-write operation to realize user program and APDL nesting mutually, giving the data in textbox to the variables in APDL command procedure, accomplishing parameters data transmission and generating the executable APDL commanding files; calling ANSYS to execute the APDL commanding files in the VB environment, and realize the structure finite element analysis calculation.The design software developed in this paper has some practicality, meanwhile, the application of parameters finite element analysis technology provide a kind of thought and method for developing the professional hydraulic supports structure design system.
