In this article, the system transfer function is established by taking identification of system for oscillating tool carrier copying and cutting system which includes the cutting process.

In this paper, the problem, such as wrinkling, in the forming of the handle of the reeling frame, are analyzed, several methods to improve its forming process are proposed, experiments and finite element simulations by using Auto Form are carried out to confirm their availability.

To solve the problems of YJ2-142 reeling frame in the press process,we build an analytical model for the handle of the reeling frame with the finite element method for AutoForm simulation demonstration.

The application of analytic hierarchy process in comprehensive safety evaluation of scaffolding;

In view of high accident rate,from bearing frame of formwork,external scaffolding,construction machinery,temporary electricity usage and other aspects content of safety supervision work in construction site is introduced.

Because of the space between two structure members(beam,column,slab etc) is large in the big space frame or bent structure building,installation of wall connecting lever for scaffolding can not be fitted for the stipulation of the technical code for safety of steel tubular scaffold with couplers in construction(JGJ130).

Cast-in-place reinforced concrete inverted cone water tower without scaffold construction;

The application of superelevation scaffold in the construction of major dam of reservoir;

Safety risk assessment of scaffolds for civil engineering construction;
