The Study Of The Steel Wire Rope Mechanical Character

The steel wire rope is widely used in many fields in national economy, such as engineer cableway, mine, lift, cable-crane, cable-stay bridge, port, and so on, in the production at present. We study the steel wire rope on the mechanical properties, then we can promote that the steel wire rope can be better in the application of each field. Whether the steel wire rope could be better applied is closely connected with its own mechanical properties. For this, this paper studies the mechanical properties of the steel wire in detail through a lot of the experiments, and the connection between breaking force of rope, modulus of elasticity and tensile strength with its structure, length, core, characteristics of spinning, force etc., and get the transformation between before or after spinning.The experiments were made about the bend, torsion, breaking force of the steel wire, measuring the data of bend, torsion, breaking force by dismantle strand test of rope.Measure the modulus of elasticity of the different length and structure of the steel wire rope, analyse the influence factors of the steel wire rope, and carry out correlation analysis and linear analysis with the software spss.Based on the experiments analysis, the conclusion is that has obvious linear correlation between the breaking force of the steel wire rope and the diameter of the steel wire; the breaking force of rope has obvious linear correlation with the diameter, number of bends, tensile strengty. The modulus of elasticity has obvious linear correlation with the tension in a certain scope. The steel wire rope used in the test basically has linear transformation in the scope of the tests. The tension increased, modulus of elastics first increased, when the tension accomplish the certain value, the value of modulus of elastics didn't increase but abase. In the experiment, we use the same steel wire rope, the number of tests increase, the modulus of elastics increase and tend to constent value until the rope burst. The modulus is not connected with the length of the rope.The conclusion based on the experiments, has the reference value to the future study of the mechanical properties in the future; at the same time, the conclusion has the reference evidence to use, choose and design of the steel wire rope.
