| Hydraulic support is a kind of hydraulic power plant, which uses liquid pressure support, and realizes the automatic shift for roof support and management.It is indispensable to the comprehensive mechanized coal mining equipment.However, hydraulic support is consumables, too heavy, the design cycle is long, the intensity is difficult to guarantee, etc.Therefore, the optimization of hydraulic support and strength analysis on the design development of support has important significance.In this tutorial, ZY2800/14/28Z screen type hydraulic support is the research object, the optimization design and finite element analysis for it.Based on the theory of optimization design, for the key component structural of hydraulic support——top beam to optimize the design, and applicate Visual Studio software to solve optimal value of four-bar linkage of hydraulic support. Then,through the SolidWorks software on hydraulic support for three-dimensional solid modeling and motion simulation analysis. Finally,using finite element analysis software ANSYS Workbench analyzes the whole static strength of hydraulic support and test the quality of the design and timely correct. Increased by increasing the thickness of steel plate and steel plate number two plans, improve the top beam structure, reduce the maximum stress value, choose the plan which safety coefficient is larger.Under the condition of structure strength, making the top beam weight eventually reduce about 21%.On the base with weak position to add auxiliary steel plate, resistance to deformation, reduce stress.The development process that optimization ——analysis——improvement improves the product quality,shortens the design cycle and saves the design cost. |
