Computer Aided Design Of Crura-Healing Equipment

This text made a series of research to Computer Aided Design of crura -healing equipment, detailed discussed VBA (Visual Basic for Application), LISP. . etc.The main research work of the thesis includes below a few aspects:First, the mechanism of crura-healing equipment is studied. Analysising and comparing the tradition construction, the original construction mode is changed. making equipments imitated to living the function stronger, the function got the improvement, according to the improvement of the construction, the timing-control system was designed so that it can positive-inverted turn.Second, the feasibility that use to study parameterized crura -healing equipment of three-dimensional is researched. and at the same time, several plans are worked out, which bring solid basis for other parameterized CAD system in the future . Most of all, a new method to analysis of finite element during its pre- management is brought into forward in this chapter, with the name of parameterized model of finite element.Last, parameterized crura-healing equipment of three-dimensional based on theoretic study is turned into reality. three-dimensional parameterized assemble is processed.
