【摘要】：本文針對(duì)現(xiàn)有片梭織機(jī)在采用扭軸式投梭方式進(jìn)行引緯時(shí)存在的沖擊大、效率低等問題,提出了一種新型的電磁力驅(qū)動(dòng)片梭雙向引緯投梭設(shè)想。以電磁學(xué)基本原理為基礎(chǔ),對(duì)現(xiàn)有的投梭引緯原理進(jìn)行改變,針對(duì)片梭引緯過程需要滿足的高速、高效、無摩擦等要求,以磁阻式原理作為研究電磁驅(qū)動(dòng)片梭投射/制動(dòng)的基本原理。文中根據(jù)所提出的電磁力驅(qū)動(dòng)引緯設(shè)想,建立了片梭電磁投射/制動(dòng)的理論模型。在單級(jí)線圈投射/制動(dòng)電路特征方程的基礎(chǔ)上,對(duì)系統(tǒng)在不同電容值和電感值情況下的投梭效果進(jìn)行了探討,分析了投射/制動(dòng)線圈外形參數(shù)與其內(nèi)部磁場強(qiáng)度之間的關(guān)系。探索了在電磁驅(qū)動(dòng)的高速雙向引緯模式下,線圈內(nèi)部的磁場分布、投射/制動(dòng)系統(tǒng)的總電感及電感梯度分布與投射效果之間的關(guān)系。并依此建立了電磁驅(qū)動(dòng)的投射/制雙向引緯模型,進(jìn)行了6級(jí)線圈的投射/制動(dòng)過程的仿真。其結(jié)果表明,電磁投射/制動(dòng)原理及設(shè)想符合片梭體運(yùn)動(dòng)規(guī)律及編織工藝要求,即可實(shí)現(xiàn)電磁投射磁懸浮雙向引緯原理方案的設(shè)想,且與普通的扭軸式投梭方式相比,在投射和制動(dòng)的過程中對(duì)片梭和紗線的沖擊更小。文中結(jié)合片梭引緯開展了磁懸浮片梭與筘座的設(shè)計(jì)。選用主動(dòng)磁懸浮原理作為磁懸浮筘座設(shè)計(jì)的基本原理,選用稀土材料的釹鐵硼永磁鐵作為片梭永磁體的材料。并以單個(gè)永磁體和電磁線圈為例,利用等效磁荷法建立了永磁體受力的數(shù)學(xué)模型,進(jìn)行了相應(yīng)的受力仿真分析,完成了片梭在磁懸浮筘座中懸浮與移動(dòng)的方案設(shè)計(jì)。通過研制的電磁力驅(qū)動(dòng)片梭雙向引緯實(shí)驗(yàn)平臺(tái),進(jìn)行了相關(guān)的驗(yàn)證性實(shí)驗(yàn),實(shí)驗(yàn)結(jié)果證明了電磁驅(qū)動(dòng)投梭引緯的可行性。文中的研究思想將為后續(xù)的電磁驅(qū)動(dòng)與磁懸浮式片梭引緯系統(tǒng)驗(yàn)證及實(shí)用化研究提供支持。
[Abstract]:In this paper, aiming at the problems existing in the existing projectile loom, such as large impact and low efficiency, when using the twisting shafting method for weft insertion, a new type of electromagnetic force driving the double direction weft insertion and shuttling of the projectile is put forward, which is based on the basic principle of electromagnetism. The principle of weft insertion is changed to meet the requirements of high speed, high efficiency, no friction and so on. The magnetoresistive principle is taken as the basic principle to study the projectile / braking of electromagnetically driven projectile. The theoretical model of projectile / braking of projectile is established. Based on the characteristic equation of single-stage coil projector / braking circuit, the effect of the system under different capacitance and inductance is discussed. The relationship between the shape parameters of the projecting / braking coil and its internal magnetic field intensity is analyzed. The magnetic field distribution inside the coil is explored in the high-speed bidirectional weft insertion mode driven by electromagnetism. The relationship between the total inductance and gradient distribution of inductance and the projection effect of the projecting / braking system is discussed. Based on this, a projection / system bi-directional weft insertion model of electromagnetic drive is established, and the simulation of the projection / braking process of the 6-stage coil is carried out. The results show that, The principle and assumption of electromagnetic projection / braking accord with the motion law of projectile and the requirement of weaving technology. The scheme of electromagnetic projection magnetic levitation bidirectional weft insertion principle can be realized, and it is compared with the conventional twisting shaft-type shuttling mode. In the process of projecting and braking, the impact on the projectile and yarn is less. In this paper, the design of the magnetic levitation shuttle and the Reed is carried out in combination with the weft insertion of the projectile. The principle of active magnetic levitation is selected as the basic principle of the design of the magnetic levitation Reed. NdFeB permanent magnet of rare earth material is selected as the material of projectile permanent magnet. Taking single permanent magnet and electromagnetic coil as examples, the mathematical model of permanent magnet force is established by using the method of equivalent magnetic charge, and the corresponding force simulation analysis is carried out. The scheme design of the suspension and movement of the projectile in the magnetic levitation Reed has been completed. The experimental platform for the two-way weft insertion of the projectile driven by electromagnetic force has been developed, and the relevant verification experiments have been carried out. The results of the experiment prove the feasibility of feeding weft insertion with electromagnetic drive, and the research ideas in this paper will provide support for the further research on electromagnetic drive and magnetic levitation weft insertion system.
