| Abstract: | Analysis of the ZZ9000/20/40 type caving shield structure design of triangle area,the reasonable simplified was established on the basis of the overall caving shield structure of 3 model.Using Cosmosworks software to analyse the two kinds of structure of caving shield subjected to torsion,impact load condition,comparison of different structure loads.Putting forward the reasonable structure design,providing a basis for design of the caving shield. |
