Buckling simulation method in fabric layer-by-layer separation process

Abstract

The invention discloses a buckling simulation method in a fabric layer-by-layer separation process. The buckling simulation method comprises the following steps: establishing a fabric warp model, a fabric weft model, a soft manipulator clamping end model and a workbench model in sequence; assembling fabric warp yarns and weft yarns, and establishing a fabric model; assembling a fabric model, a soft manipulator clamping end model and a workbench model according to an actual grabbing environment, and establishing a fabric layer-by-layer separation model; pre-treatment conditions are set and input into finite element analysis software ABAQUS, operation is established and submitted for analysis according to a fabric layer-by-layer separation model, the fabric layer-by-layer separation process is calculated, and a buckling simulation result is output; according to the method, the change of the stress and the buckling height of the fabric along with the change of the grabbing parameters in the layer-by-layer separation process is obtained through a finite element analysis method, so that the layer-by-layer grabbing accuracy is improved, the real fabric grabbing environment can be simulated, and the time and the material cost are saved.

Description

technical field [0001] The invention relates to the technical field of fabric buckling simulation, in particular to a buckling simulation method in the process of fabric layer-by-layer separation. Background technique [0002] In recent years, the automated processing of fabric layer-by-layer separation process needs to be developed urgently. Among them, the soft manipulator designed based on the theory of bionics can simulate the bending and twisting of human fingers, and the materials are mostly flexible materials, which have good affinity with fabrics, and become an important research direction for the automatic processing of fabric layer-by-layer separation. . The buckling height of the fabric is a key factor in the layer-by-layer separation process, however, the buckling behavior of the fabric is very complex during the grasping process of the soft manipulator.

The buckling height of the fabric is a key factor in the layer-by-layer separation process, however, the buckling behavior of the fabric is very complicated during the grasping process of the soft manipulator

At this stage, the buckling behavior of fabrics is generally explored through trial-and-error experiments and data regression modeling. The comprehensive cost is high, the scope of application is narrow, and the reliability is average. It has poor flexibility and adaptability to the application scenarios of multi-material and multi-tissue structures in clothing production.
