New DTW algorithm based on segment cutting in parallel;

In this paper a new algorithm named sectional sorting and cutting method about reducing DTW algorithm operation quantity is described.

The computation and software used in form-finding analysis are brought out; the optimized way of cutting pattern analysis is put forward; the construction quality control and maintenance of the cable-membrane structure are introduced in details.

The theory of its design mainly includes three aspects: shape-finding analysis、load analysis and patterning analysis.

Geodesic line generation by nonlinear finite element method in cutting pattern for membrane structures;

The simulation of curved surface and the generation of geodesic lines in the cutting pattern for membrane structures are discussed in the paper, it is two important problems in the cutting pattern.

In connection with the problem of releasing the prestressing forces in membrane structures which is a key problem in cutting pattern of membrane structures, this paper builds the calculating model for releasing the prestressing forces in membrane structures by elastic dynamic mechanics principle.
