Journal of Intelligent and Fuzzy Systems, 2023
Fault diagnosis of rapier loom is an inevitable requirement to meet the demand of intelligent manufacturing. Facing the strong noise interference caused by complex working environment, accurate and reliable vibration signal detection of blade loom spindle is the key to realize the rapier loom fault diagnosis. This paper proposes a method to extract the

Dynamics of the picking mechanism of a rapier loom
Mechanism and Machine Theory, 1992Abstract This paper deals with the mathematical modelling of the picking mechanism of a rapier loom. The dynamic model approximately respects mass, flexibility and kinematic excitation of the mechanism. It consists of two subsystems. The first subsystems is a discrete one, the second subsystem is a continuous one.

Optimal analysis and application of the warp tension control system for a rapier loom
Textile Research Journal, 2021Traditional proportional–integral–derivative (PID) control performance optimization is an essential method to improve a loom’s warp tension control performance. This work proposes an improved genetic algorithm optimized PID control scheme to overcome the decline in control performance of the traditional PID control algorithm in a loom’s warp tension ...

Research on Electric Weft Insertion Method for the Rapier Loom
Applied Mechanics and Materials, 2012This paper, on analyses of the shortages of the traditional rapier loom weft insertion system such as unalterable motion rules and high machining accuracy requirements, introduces a new electric weft insertion method to the modern high-speed rapier loom, which converts single-direction rotation of a motor to linear reciprocation of a rapier with help ...

A numerical model of the weft yarn filling insertion process in rapier looms
2006 American Control Conference, 2006This paper presents a mathematical model of the weft yarn filling insertion process in rapier looms. A finite length segment of yarn is spatially discretized. Each element can interact only with the nearest neighbors by a viscoelastic interaction. The elastic and damping constants have been estimated by using experimental data obtained with different ...

The Stability of Weft Insertion of CRT – 83 Carpet Rapier Loom
Applied Mechanics and Materials, 2013CRT- 83 carpet rapier loom is a kind of high-grade rigid rapier loom，the weft yarn will give looms to demand higher stability of the weft insertion. Theoretical analysis based on the theory research of the stability of clamping weft and weft handover shows that the rapier deformation，slipping force and the depth of clamping are main factors influencing
