A study of the measuring and strength size effect of the surface shape of structure plane

The surface shape of structure plane is closely related to its mechanics property.At present,the accurate measurement of structure plane surface shape is the foundation of the mecanism of studying the deformation and strength of structure plane.On the basis of examining the advantages and disadvantages of the measuring instrument,a kind of portable measuring instruments,a contact punching device,is innovatively developed,which has realized the mechanization that is finely measured the rigid stru...
