Abstract


One of the reverse engineering of contemporary modern design methods and advanced manufacturing technology has been developed as integrated technology , reverse design is an important means of modern innovative design and optimization design for the study of biological structure Bionic Design is by means of reverse design theory and methods to achieve an important way for the re-creation of the design has important theoretical and practical significance , therefore , based on the research and development of the bionic design of industrial products . The subject to the turtle shell as the research object , the geometric characteristics and mechanical properties of the original bionic surfaces belong to the complex free-form surface is difficult to achieve precise manufacturing , so to study the geometric characteristics and mechanical properties of a succession of turtle shell which is can use modern manufacturing precision manufacturing variants curved main tasks : ( 1 ) to Pro / E software as a platform to build the shell of the original surface model , analysis of the cross-sectional shape of the bones included in the housing rib row cloth form, constructed within the additional gluten free surface model . (2) do an in - depth discussion on Pro / E and Matlab data exchange building occurred lines derived surfaces from the shell . ( 3) using Pro / Mechanica module reconstructed free-form surface , derived surfaces, the additional strong gluten derived surface from mechanical bearing properties of the finite element analysis . ( 4 ) the use of Pro / NC module CNC machining simulation derived surface mold body surfaces .
