【摘要】：直線永磁同步電機(jī)能夠以“零傳動(dòng)”的方式將電能直接轉(zhuǎn)化為直線運(yùn)動(dòng)的機(jī)械能，將其應(yīng)用于直接驅(qū)動(dòng)領(lǐng)域時(shí)，相比于傳統(tǒng)的驅(qū)動(dòng)方式在速度、加速度和定位精度等方面有很大優(yōu)勢(shì)。在國(guó)外，使用直線永磁同步電機(jī)驅(qū)動(dòng)的高速高精加工中心已經(jīng)非常普遍，但是在我國(guó)，直線永磁同步電機(jī)性能的測(cè)試和評(píng)價(jià)技術(shù)一直缺乏成熟的標(biāo)準(zhǔn)，阻礙了直線永磁同步電機(jī)在一些高精度領(lǐng)域的使用。 本文對(duì)直線永磁同步電機(jī)的力特性，，即定位力、推力波動(dòng)等的測(cè)試技術(shù)進(jìn)行了研究，主要內(nèi)容包括以下幾個(gè)方面： 首先，對(duì)直線永磁同步電機(jī)的力特性進(jìn)行分析，以推力產(chǎn)生波動(dòng)的主要原因?yàn)殚_端分別對(duì)直線永磁同步電機(jī)的紋波推力、齒槽定位力和端部定位力進(jìn)行了解析分析，并對(duì)最終將用于測(cè)試實(shí)驗(yàn)的樣機(jī)進(jìn)行了定位力和推力的有限元仿真計(jì)算，解析分析和仿真計(jì)算為最終的測(cè)試實(shí)驗(yàn)結(jié)果分析提供理論基礎(chǔ)和參考。 其次，對(duì)直線永磁同步電機(jī)力特性的測(cè)試方案進(jìn)行了研究，簡(jiǎn)單分析了基于直線伺服電機(jī)加載和基于旋轉(zhuǎn)伺服電機(jī)加載的兩種測(cè)試方案的特點(diǎn)，提出了一種基于直線電磁阻尼器加載的測(cè)試方案，并在基于旋轉(zhuǎn)伺服電機(jī)加載的測(cè)試方案的基礎(chǔ)上介紹了力特性的測(cè)試方法。 再次，對(duì)基于旋轉(zhuǎn)伺服電機(jī)加載的測(cè)試系統(tǒng)進(jìn)行了設(shè)計(jì)，分析了測(cè)試的原理，通過建立其數(shù)學(xué)模型分析了其動(dòng)態(tài)特性，并通過有限元仿真軟件對(duì)測(cè)試系統(tǒng)的結(jié)構(gòu)進(jìn)行了模態(tài)分析和諧響應(yīng)分析，從動(dòng)力學(xué)分析的角度為測(cè)試系統(tǒng)的設(shè)計(jì)和使用提供了指導(dǎo)。 最后，加工完成一套測(cè)試系統(tǒng)，在實(shí)驗(yàn)室條件下，進(jìn)行力特性的測(cè)試實(shí)驗(yàn)，對(duì)測(cè)試實(shí)驗(yàn)結(jié)果進(jìn)行分析，與前文的理論分析結(jié)果進(jìn)行對(duì)比，以驗(yàn)證測(cè)試方法的正確性和測(cè)試系統(tǒng)的有效性，并對(duì)測(cè)試系統(tǒng)的誤差進(jìn)行分析。
[Abstract]:The linear permanent magnet synchronous motor can convert electrical energy directly into the mechanical energy of linear motion by "zero drive". When it is applied to the direct drive field, compared with the traditional driving mode, it is at the speed. Acceleration and positioning accuracy have great advantages. In foreign countries, the high speed and high precision machining center driven by linear permanent magnet synchronous motor is very common, but in our country, the testing and evaluation technology of linear permanent magnet synchronous motor performance has been lack of mature standard. It hinders the use of linear permanent magnet synchronous motor in some high precision fields. In this paper, the force characteristics of linear permanent magnet synchronous motor (PMSM), that is, the measurement technology of positioning force and thrust fluctuation, are studied. The main contents include the following aspects: First of all, the force characteristics of linear permanent magnet synchronous motor are analyzed, and the ripple thrust, slot positioning force and end positioning force of linear permanent magnet synchronous motor are analyzed. The finite element simulation calculation of the positioning force and thrust is carried out for the prototype which will be used in the test experiment finally. The analytical analysis and simulation calculation provide the theoretical basis and reference for the final test experiment result analysis. Secondly, the testing scheme of linear permanent magnet synchronous motor is studied, and the characteristics of two test schemes based on linear servo motor loading and rotating servo motor loading are analyzed. A testing scheme based on linear electromagnetic dampers is proposed, and the test method of force characteristics is introduced on the basis of the test scheme based on rotating servo motor loading. Thirdly, the test system based on rotating servo motor loading is designed, the principle of the test is analyzed, and its dynamic characteristics are analyzed by establishing its mathematical model. The modal analysis and harmonic response analysis of the structure of the test system are carried out by the finite element simulation software, which provides guidance for the design and application of the test system from the point of view of dynamic analysis. Finally, a set of testing system is completed, and the test results of the force characteristics are tested under the laboratory conditions. The results of the test experiments are compared with those of the previous theoretical analysis. In order to verify the correctness of the test method and the validity of the test system, the error of the test system is analyzed.
