Research on the Problem of Contact Characteristic Finite Strip and Its Characteristic Agent

The deformation mechanism of cold-formed steel is very complex, the relation between the deforming forces exerted and the deformation of steel strap can not be described by simple function. In order to reduce data redundancy, adopt the characteristic finite strip method which can solve primary illogicality. The characteristic finite strip can be divided into 3 kinds, thereinto, "the characteristic finite strip contacted with roller" can parse the effect roller energy to steel strap deform and the influence steel strap and roller friction to deformation. So, research on this kind of finite strip looks very important. Making this kind of characteristic of finite strip has informatization and intelligentize have instructed effect to the intelligence of pass design. Adopt characteristic Agent is the relative good method of making the characteristic finite strip has intelligence.
