基于Pro/E与ANSYS的柔掩支架优化设计

Optimal Design of the Flexible Shield Support Based on Pro/E and ANSYS

柔性掩护支架广泛应用于急倾斜煤层开采中,支架的结构形式及材料属性决定着支架的支护强度。长沟峪煤矿在利用柔性掩护支架开采过程中,由于煤层顶板破碎,应力较大,导致支架破损率较大,出现支架变形、扭坏、焊口开裂等现象。本文利用Pro/E软件建立柔性掩护支架的三维模型,利用有限元分析软件ANSYS对支架的强度和刚度进行了数值模拟与分析,确定了支架表面应力和应变的薄弱点。针对柔性掩护支架的不足之处,对其结构进行了调整和优化,并再次进行模拟分析,获得了柔性掩护支架的最佳结构。

The flexible shield support is widely used in steep seam mining.The structure and material properties of support determine support strength.In the process of flexible shield used by Changgouyu coal mine when mining,due to broken roof and a larger stress,it has resulted in higher rates of support damage,support deformation,torsion break,welded joints crack occur frequently.The software Pro/E is utilized to establish three-dimensional model of flexible shield support,the finite element analysis software ANSYS to simulate and analysis the strength and rigidity of the support to determine the weak points of the support surface stress and strain.According to the shortcomings of the flexible shield support,its structure is adjusted and optimized,and simulate again,we have accessed to the best structure of flexible shield support.
