摘要
通过实物就液压支架在使用过程中发生部分顶梁失效的成因和对作用其上载荷的形式及方式进行了详细地论述,并对液压支架顶梁弯曲变形及开裂失效成因进行了分析计算。
Based on material objects,for the causes of partial top-beam inefficiency on use and the forms, methods of loading acted are discussed detailedly. Counts and analyses the causes of winding deformation and cracking inefficiency on top-beam of hydraulic support.
