/> <a href='http://www.www.htspipe.com.cn/' target='_blank'>加工中心</a>是我國裝備制造業的基礎，也是我國實現 工業2025的重要技術環節。<a href='http://www.www.htspipe.com.cn/' target='_blank'>加工中心</a>設備性能好壞、加 工效率的高低與<a href='http://www.www.htspipe.com.cn/' target='_blank'>機床</a>主軸的靜動態特性有重大的關系。 因此，對主軸系統進行靜動態分析就有很重要的意義。<br /> 1主軸靜力學分析<br /> <a href='http://www.www.htspipe.com.cn/' target='_blank'>機床</a>主軸抵抗靜態外力的衡量標準是靜剛度。一般 情況下，主軸的彎曲剛度比軸向剛度重要，通常用彎曲剛 度衡量主軸的靜剛度。主軸的彎曲剛度可以定義為:主軸 在徑向力作用下產生的單位徑向位移[1]。<br /> 1.1靜力分析的剛度方程<br /> 根據動力學問題單元構造的基本表達式[2]<br /> Meqe+ceq e+Keqe=p e， (D<br /> 可以得到某一系統的整體有限元方程，即<br /> Mq,+Cq,+Kq,=P,。 （2)<br /> 式中為節點位移矩陣；，為節點速度矩陣；，為節點加 速度矩陣;M為系統質量矩陣;C為系統阻尼矩陣陣;K為系 統剛度矩陣；，為系統外力矩陣。<br /> 由于靜力學情形時，與時間無關，則方程為<br /> Kq=P。 ⑶<br /> 這就是結構靜力分析的整體剛度方程。<br /> ANSYS分析得到主軸的靜態位移q，根據方程<br /> K=p， ⑷<br /> q<br /> 得出主軸的彎曲靜剛度。<br /> 基金項目：014年度內蒙古工業大學科學研究基金項目 (X201429)<br /> 1.2主軸有限元模型建立<br /> SV-41<a href='http://www.www.htspipe.com.cn/' target='_blank'>加工中心</a>主軸是一種中空、多支撐的階梯軸。 軸承承受多種外力的作用，因此有非線性彈性形變，根據 有限元分析理論，建立主軸有限元模型時要做適當的簡 化。簡化角接觸球軸承為彈性支撐，忽略軸承角剛度只取 徑向剛度，將軸承模擬為徑向彈簧單元。不考慮軸承載荷 的影響，電機轉子假設為軸材料等效到主軸上'<br /> 根據上述模型簡化分析，選擇ANSYS中的solid187 單元模擬軸，選擇combin14彈簧-阻尼單元模擬軸承[4]。<br /> 利用SolidWorks軟件建立主軸三維模型，通過 ANSYS接口導人，進行必要簡化后選擇solid187單元選 項對主軸劃分網格，定義材料屬性，賦予主軸combin14 彈簧-阻尼單元，可得到主軸有限元模型，如圖1所示。<br /> 1.3靜態特性分析結果<br /> 選擇ANSYS的Static分析模塊，對主軸施加相應的 約束，在主軸前端施加徑向載荷2167N(通過切削力計算 得到)，ANSYS靜力分析得到主軸靜態變形圖(圖2所示）。<br /> 據圖2知主軸變形最大的部分出現在主軸前端，最 大靜態位移qDMX=2.89 ^m，主軸的彎曲靜剛度K=i =<br /> 2167<br /> 2.89<br /> =749.83 N/^m〇<br /> 2主軸動力學分析<br /> 加工中心主軸的動態特性很大程度上決定了加工中 心的加工質量和切削能力。主軸的動態性能是指主軸抵 抗受迫振動和自激振動的能力=]。受迫振動幅值與激振 力頻率相關，如果主軸的某階固有頻率與激振頻率相近 或相等，結果會使振幅劇增，主軸會發生共振現象。所以 主軸的各階固有頻率是評價動態特性的重要內容。<br /> 2.1動態特性數學模型<br /> 根據系統的整體有限元方程式(2)，考慮主軸系統自 由振動時，忽略系統的阻尼及外力影響，可以得到系統的 無阻尼自由振動方程<br /> Mq+Kq=0。 ⑶<br /> 該方程解的形式為簡諧振動形式<br /> q,=^-ei™'。 (6)<br /> 式(6)帶人式⑶有<br /> (K-«2M)q=0。 （7)<br /> 方程(7)有非零解的條件是<br /> I(K-M2M)I=0。 （8)<br /> 求得自然圓頻率~后可以得到對應的頻率/=+，再<br /> 2n<br /> 將其帶人式(7)可以得到對應于振動頻率的振型。<br /> 利用ANSYS進行模態分析，獲得主軸固有頻率和振 型，根據公式n=60/得到主軸臨界轉速。<br /> 2.2模態分析<br /> 模態分析是動力學分析的基礎，模態分析就是分析 結構的固有頻率與振型，所以主軸的模態分析是主軸動 態特性的首要分析問題。<br /> 在ANSYS軟件中，打開已建立好的主軸有限元模型 (圖1所示），選擇Modal分析模塊中的Block Lanczos模 態提取法獲得前八階固有頻率及振型，根據固有頻率得 到主軸臨界轉速(表1所示）。<br /> 據表1，主軸的一階、二階固有頻率值近似，視為式⑶ 的重根，同理，主軸的四階、五階固有頻率值近似，六階、 七階固有頻率值近似。主軸模態振型圖如圖3~圖10。<br /> 3結論<br /> 1) 利用ANSYS對主軸進行了靜態特性分析，計算出了 最大位移qDMX及彎曲剛度K該剛度完全滿足主軸削加工 的需要。機床在實際加工中，主軸前端會安裝軸頭、刀具 等，所以實際工作中剛度會高于計算值。如剛度不足，可以 通過重新選擇和配置軸承等方式改進主軸部件的結構。<br /> 2) 通過模態分析，得到了主軸前八階固有頻率和振型， 計算出主軸臨界轉速。SV-41加工中心機主油的最高轉速為12000r/min，遠低于H階臨界轉速15918.6r/min，可以保證主軸 在額定轉速附近工作不會發生共振，能夠保證加工中心 的加工精度。</p> <div> <table cellspacing="0" cellpadding="0" hspace="0" vspace="0"
