calculation and control of alignment error of double spiral gear 偏差的計算和控制
the alignment error and positioning precision of the wiggler are analyzed 對超導(dǎo)扭擺磁鐵準(zhǔn)直的誤差和精度進(jìn)行了分析。
base on the model of grating-pair compressor, the formula of angular dispersion caused by alignment errors was derived 摘要根據(jù)失調(diào)拼接光柵對壓縮系統(tǒng)模型,推導(dǎo)了拼接誤差引起的角色散公式。
the flexibility of the structure / mechanism joints and the alignment errors significantly affect the structure / mechanism experiment results 接頭的柔性和安裝誤差對結(jié)構(gòu)/機(jī)構(gòu)可靠性實驗有很大影響。
because of the influence of alignment error on ground and launch vibration, it is impossible for eut to keep four channels parallel perfectly . and this will bring error of observation 由于在地面裝調(diào)以及發(fā)射過程中的影響無法保證四個通道軸向嚴(yán)格平行,進(jìn)而帶來觀測上的誤差。
