Abstract
Item connection method during the fabric product’s computer assembling is presented in the paper. The fabric is considered as a system of interacting particles which placed in the direct and cross-cut cross points of the sheets’ fiber. The item outline (pattern) is used as an initial data to construct item grid model. That outline has the form of any polygon. The grid has to be uniform with square-shaped cells so the active forces occurring in the simulating product were brought in modulus and direction to the forces of the real material that occurs with its deformation. Physical methods such, as particle method, are used for simulation. To solve the dif-ferential equation system the leapfrog scheme is used. Because of such approach the fabric computer model can virtually with high accuracy to reproduce all deformations of real materials. Proposed product items connection method consist of such steps as identification of the bonding particles location for connecting items, development of the bonding particles behavior during assembling process model and finding the material tension areas after assembly. Method allows carrying out the product assembling on the solid object’s surface and without it. To confirm the method effectiveness the details of basic construction and results of cotton fabric product assembly on the solid plane-bounded object surface are presented. The object is female figure's mannequin.
Keywords: product items connection method, fabric computer simulation, sampling of the free-form items, uniform mesh, bonding particles location on the item profile, binding particles behavior during assembling, particle method, leapfrog scheme
