摘要
为了提升液压支架应用效果,以ZY1000/0.8/1.5型掩护式液压支架为例,通过有限元法对液压支架销轴静力学特性进行模拟分析,利用多目标优化设计法确定销轴结构优化方案。研究发现:液压支架运行时,销轴主要受到剪力的影响,其中,轴向方向呈受压状态,以压应力与先应变为主,剪切力越大,应力与应变越高;销轴最佳优化方案为:盲孔直径由26 mm减小到23 mm,盲孔深度由13 mm减小到10 mm,盲孔间凹槽宽度由11 mm减小到10 mm。通过实践应用验证了优化方案的合理性,可显著降低销轴的应力与应变水平,有利于提升销轴的使用寿命。
To enhance the effectiveness of hydraulic support systems,this study investigates the ZY1000/0.8/1.5 shield-type hydraulic support using finite element analysis to evaluate pin shaft static characteristics.Through multi-objective optimization design,we developed an optimized pin shaft structure.The findings indicate that during operation,the pin shaft primarily experiences shear forces,with axial compression as the dominant stress mode characterized by compressive stress and initial strain.Increased shear forces correspond to higher stress and strain levels.The optimal configuration involves reducing blind hole diameter from 26 mm to 23 mm,decreasing blind hole depth from 13 mm to 10 mm,and narrowing inter-blind groove width from 11 mm to 10 mm.Field validation demonstrates the rationality of this optimization approach,which significantly reduces stress and strain levels in the pin shaft while extending its service life.
