It has proved that ehtv method is reasonable and convenience , the calculating error is little between ehtv method and doe - 2 program Ehtv的研究表明其方法合理,使用方便,和動態(tài)模擬程序doe一2的計算結(jié)果相比, ehtv的計算結(jié)果誤差較小,數(shù)據(jù)可靠。
The calculated error can be in one of two partitions about the desired accuracy , a feature of the structural design for the unit , which is not apparent from a purely functional specification 錯誤可能是在二類劃分的當(dāng)中一個中關(guān)于準(zhǔn)確性,結(jié)構(gòu)設(shè)計的特點為單元,不是明顯的從一個單純的功能規(guī)格。
With the differential method , error that is produced by many factors is combined into macro motion of position and pose of manipulator . reason and calculate error of the end and joints , then get the relation expression of the error of the end and the error of joints 利用微分法,把各方面產(chǎn)生的誤差歸結(jié)為機械手的位置與姿態(tài)的微運動,對終端誤差與各關(guān)節(jié)的誤差進行推導(dǎo)、計算,從而得出終端誤差與關(guān)節(jié)誤差之間的關(guān)系式。
This method applied to the measurement of precision of original azimuth of underwater to surface missile , through measuring exterior information using optical measurement device , measuring accurate position of shore beacon , calculating error of missile aiming system 通過光測設(shè)備測量系統(tǒng)外部的信息,測量岸標(biāo)的精確位置,來推算系統(tǒng)的瞄準(zhǔn)誤差。對外測岸標(biāo)法,建立了數(shù)學(xué)模型,詳細(xì)討論了外測岸標(biāo)的標(biāo)定方法、原理和方位角的解算。
This model and the experiment solution can restrict the calculating error of the forming time to seconds which have important reference to externally quoting , arranging the working sequence and balancing the priority between the process efficiency and prototyping function of sls provider 該模型和實驗方法可將sls成型時間的計算誤差控制在秒內(nèi),這對于sls服務(wù)方的對外報價、安排作業(yè)順序和權(quán)衡加工效率與成型件性能之間的優(yōu)先權(quán)有十分重要的參照作用。
