Pattern morphology in the elastic sewing machine

We present results from a numerical investigation of the coiling patterns obtained when a slender elastic rod is deployed onto a moving substrate. The Discrete Elastic Rods method is employed to explore the parameter space, construct phase diagrams, identify their phase boundaries and characterize the pattern morphology. The various length scales of the patterns are primarily set by the gravity...

A Design Support System for Kaga-Yuzen Kimono Pattern by Means of L-System

This paper proposes a support tool for designing kimono patterns. Kimono patterns are controlled by two rules, “flow” and “hierarchy”; the rule of “flow” controls the pattern arrangement, and the rule of “layered structure” manages the layer structure of pattern. The proposed system supports design of kimono patterns, considering these two rules. The system also applies L-System to express orna...

A numerical investigation of the fluid mechanical sewing machine

A thin thread of viscous fluid falling onto a moving belt generates a surprising variety of patterns depending on the belt speed, fall height, flow rate, and fluid properties. Here, we simulate this experiment numerically using the discrete viscous threads method that can predict the non-steady dynamics of thin viscous filaments, capturing the combined effects of inertia and of deformation by s...

Neural Network-Based System Identification and Controller Synthesis for an Industrial Sewing Machine

The purpose of this paper is to obtain an accurate nonlinear system model to test various control schemes for a motion control system that requires high speed, robustness and accuracy. An industrial sewing machine equipped with a Brushless DC motor is considered. It is modeled by a neural network that is configured as an output-error dynamical system. The identified model is essentially a one s...
