The Research on the Influence Cause of Boron Steel Sheet Size Precision Based on Automobile Light Quantizing

Abstract:

The influence cause of boron steel sheet on size precision is studied, which is contained with additional drawing stress, emergency ratio, board deep, plastic modulus, subdued point, sclerotic index, crushing force, curvature radius and so on .In order to lay the further foundations of optimizing design, it is analyzed that the latent relation of influence cause of boron steel sheet on size precision by orthogonal experiment. It is pointed orderly out that the influences with rebound result of certain automobile back wheel casing are that sheet crushing force occupies the first place, sheet thick comes second, and sclerotic index comes third, emergency ratio and curvature radius in order. It is reached that the lowest rebound condition formed of certain automobile back wheel casing drawing, the rebound way controlled is given to boron steel sheet on size precision.
