Influence of concrete square column s section fillet on strengthening effect of carbon fiber;

Study on Fillet Radius and Sinkage of Gasoline Engine Crank

The solid modeling of the fillet on the intersection line of two cylinders is a difficult problem in CAD and CAM, all the soft wears have no such function.

In the paper, the contact and frictionstates of a strip at die shoulder is studied by FEM simula-tion when strip is pulled through the shoulder withstretching force.

Plate pulled through shoulder is a general problem in stamping,that is also a difficult point in sheet forming technology.

The deformation and mechanical state of sheet at shoulder largely affect the sheet forming performance That is a basic theory problem of sheet forming In this paper,the influence of shoulder radius,back tension and friction condition on strip pulled through shoulder are studied by FEM simulation The deformation and mechanical features of strip at different states are discusse

The parameterized geometric model of the universal profiled roll is built with software ANSYS,the rigidity and weight of the housing is used as object function,then the housing fillet angle is optimized by multiple-object optimization method.

Especially, pay attention to quality of rounded corner, avoid 'development based on experience'.
