style="text-indent:25px">高精度角度編碼器的誤差檢測是編碼器制作過程中不可或缺的一個環(huán)節(jié).對于高精度光電編碼器，細分誤差是影響其準確度的主要因素.現(xiàn)有的細分誤差檢測主要采用精密的小角度測量儀，光學(xué)多面體等儀器，要求在嚴格的實驗室條件下進行，檢測方法費時，費力，易引入檢測誤差.對碼盤光柵節(jié)距較小，細分份數(shù)較高的高精度編碼器的細分誤差以及工作現(xiàn)場的動態(tài)細分誤差的快速檢測，還沒有有效的檢測手段.本文主要研究的是高精度編碼器動態(tài)細分誤差的測量方法.在參考國內(nèi)外大量文獻的基礎(chǔ)上，首先從莫爾條紋產(chǎn)生的原理出發(fā)，深入分析了高精度編碼器莫爾條紋光電信號的特點，影響莫爾條紋質(zhì)量的因素，貴州高清編碼器廠家，莫爾條紋信號質(zhì)量對細分誤差的影響，研究了高精度編碼器細分誤差的計算方法.提出了利用傅立葉變換進行高精度編碼器動態(tài)細分誤差的計算方法.采用傅立葉分析算法對莫爾條紋信號進行分析研究，計算信號波形參數(shù)，貴州高清編碼器廠家，與標準信號進行比對，求出動態(tài)細分誤差，貴州高清編碼器廠家.建立了莫爾條紋的時域信號向空域位置信號轉(zhuǎn)換的數(shù)學(xué)模型。在高精度角度編碼器中角位移的轉(zhuǎn)換采用了光電掃描原理。貴州高清編碼器廠家</p><div

style="text-indent:25px">高精度角度編碼器的優(yōu)點：體積小，精密，本身分辨度可以很高，無接觸無磨損;同一品種既可檢測角度位移，又可在機械轉(zhuǎn)換裝置幫助下檢測直線位移;多圈光電***編碼器可以檢測相當(dāng)長量程的直線位移(如25位多圈)。壽命長，安裝隨意，接口形式豐富，價格合理。成熟技術(shù)，多年前已在國內(nèi)外得到普遍應(yīng)用。缺點：精密但對戶外及惡劣環(huán)境下使用提出較高的保護要求；量測直線位移需依賴機械裝置轉(zhuǎn)換，需消除機械間隙帶來的誤差；檢測軌道運行物體難以克服滑差。</p><p

style="text-indent:25px">目前市面上常見的高精度角度編碼器有光電式和磁電式高精度角度編碼器兩種，其中光電式高精度角度編碼器占市場主導(dǎo)地位，其發(fā)展比較早，技術(shù)比較成熟，精度比較高。但是光電式高精度角度編碼器也有許多缺點：玻璃光盤的抗震性能比較差，對塵埃和結(jié)露等環(huán)境要求比較高，另外玻璃光盤的刻線有一定的物理限制，部品點數(shù)比較多，不利于小型化，組裝比較復(fù)雜困難，對組裝的環(huán)境要求比較高，成本相對的也就比較高。早期光學(xué)高精度角度編碼器的工作原理在刻度盤（碼盤）的一邊是發(fā)光管（光源），另一邊是光電接收管（光檢測器），刻度盤隨著被測軸的轉(zhuǎn)動使得透過刻度盤縫隙的光束產(chǎn)生間斷，通過光電接收管的接收和電子線路的處理，產(chǎn)生特定電信號的輸出，再經(jīng)過數(shù)字處理可計算出位置和速度信息。高精度角度編碼器故障導(dǎo)致其不能產(chǎn)生和輸出正確的波形。青海高精度編碼器</p><p
