Experimental Study on Mechanical Characteristics of the End Plates of Lebus Drum

摘要

The mechanical characteristics of the end plates of Lebus dram were investigated by an experimental approach.Strain-electricity method was used to test the stress of the end plates of the drum.Experimental results show that the equivalent stress exerted on the end plate is 3 time higher than the stress obtained by the conventional calculation method.The stress exerted on the end plate of one side of Lebus drum grows one time as the wire rope adds two layers according to the winding process and the increment of the stress becomes larger and larger with the wire rope layer number increasing.When the wire rope rise from the 10th layer to 11th layer,the increment of the stress in radial direction on the end plate of the entry side reaches up to 54.9 [Mpa].
