So every course can call public subroutine program on the basis of demand . the cad system have validated by many applied double _ arc gears examples , and its error are very small 本系統(tǒng)的計(jì)算結(jié)果經(jīng)多次實(shí)際應(yīng)用齒輪的結(jié)果驗(yàn)證,并與有關(guān)資料中的精確計(jì)算數(shù)值相對(duì)照,誤差很小。
The paper also introduces the method of subroutine programming to lab view with dynamic link library ( dll ) supporting its significant property . by extending digital filter subroutines , it supplies a gap to lab view 為彌補(bǔ)labview里數(shù)字濾波器子程序欠缺之不足,本文研究了labview和visualc + +環(huán)境下應(yīng)用動(dòng)態(tài)鏈接庫(kù)dll技術(shù)對(duì)數(shù)字濾波器進(jìn)行開發(fā)的方法。
For offstandard double circular - arc gears , calculate its shape coefficient using its basis parameters of shape . so we can design universal double circular - arc gears . this paper designed the subroutine program of chart and parameter table 對(duì)非標(biāo)準(zhǔn)的雙圓弧齒輪,通過(guò)基本的齒形參數(shù),用折截面法計(jì)算得出它的齒形系數(shù),從而可以實(shí)現(xiàn)通用的雙圓弧齒輪的設(shè)計(jì)。
The following conclusions and innovation can be obtained : ( 1 ) the marc finite element analysis software and subroutine program is used to analyse the model of deicing or snow - melting and heat transfer problems in practical deicing or snow - melting successfully . the results are found to be in good agreement with relevant literature . when the wind scale exceeds 3 , the influence of wind is apparent and must be taken into account in practical design 得到了以下的結(jié)論和創(chuàng)新性成果: ( 1 )借助于marc有限元程序和自編的用戶子程序成功地分析了融雪化冰模型,并解決了融雪化冰中所涉及的熱傳導(dǎo)計(jì)算問題,得到的結(jié)果與相關(guān)文獻(xiàn)吻合得較好。
