Abstract:To solve the vibration problem of double-layer weft insertion mechanism of double-layer rapier loom, this paper establishes the rigid-flexible coupling dynamic model of double-layer weft insertion mechanism of sword wheel-rapier-air cushion guide impact vibration, conducts the simulation analysis of rapier transient vibration characteristics, and designs the vibration test platform to modify the parameters of the simulation model. The reserch presents an accurate simulation model for the design and improvement of double-layer rapier loom.

Keywords:double-layer rapier loom;vibration system;modeling;simulation

0 引言

工程織物用雙層劍桿織機(jī)是目前較先進(jìn)的制造設(shè)備,由于齒輪齒條的嚙合振動(dòng)與傳動(dòng)軸的往復(fù)扭轉(zhuǎn)振動(dòng)[1],高速往復(fù)運(yùn)動(dòng)的劍桿會(huì)發(fā)生劇烈振動(dòng),嚴(yán)重影響了雙層劍桿織機(jī)的工作穩(wěn)定性,降低了織物質(zhì)量和生產(chǎn)效率。(剩余3180字)
