1、牛頭刨床導(dǎo)桿機(jī)構(gòu)運(yùn)動(dòng)分析一、 設(shè)計(jì)任務(wù)及要求:(1)已知：牛頭刨床的導(dǎo)桿機(jī)構(gòu)的曲柄每分鐘轉(zhuǎn)速n2，各構(gòu)件尺寸及重心位置，且報(bào)頭導(dǎo)路x-x位于導(dǎo)桿端點(diǎn)B所作圓弧的平分線(xiàn)上。數(shù)據(jù)如下表所示：設(shè)計(jì)內(nèi)容導(dǎo)桿機(jī)構(gòu)運(yùn)動(dòng)分析單位r/min mm符號(hào)N2lo2o4lo2Alo4BlBClo4s4數(shù)據(jù)7040095800要求：1、用c語(yǔ)言編寫(xiě)計(jì)算程序,對(duì)機(jī)構(gòu)進(jìn)行動(dòng)態(tài)分析和動(dòng)態(tài)顯示。2、上機(jī)調(diào)試程序并打印結(jié)果。3、畫(huà)出導(dǎo)桿4的角位移，角速度，角加速度的曲線(xiàn)。4、編寫(xiě)設(shè)計(jì)計(jì)算說(shuō)明書(shū)。二、數(shù)學(xué)模型的建立 如圖三個(gè)向量組成封閉圖形，于是有按復(fù)數(shù)式可以寫(xiě)成a（cos+isin）-b(cos+isin)+d(cos3+is

2、in3)=0 （1）由于3=90，上式可化簡(jiǎn)為a（cos+isin）-b(cos+isin)+id=0 （2）根據(jù)（2）式中實(shí)部、虛部分別相等得acos-bcos=0 (3)asin-bsin+d=0 (4)(3)(4)聯(lián)立解得=arctan (5)b= (6)將（2）對(duì)時(shí)間求一階導(dǎo)數(shù)得2=1cos(-) (7)c=b=-a1sin(-) (8)將（2）對(duì)時(shí)間求二階導(dǎo)數(shù)得3=a1cos(-)- asin(-)-2c2 （9)ac=b”=-a1sin(-)-acos(-)+b (10)ac即滑塊沿桿方向的加速度，通常曲柄可近似看作均角速轉(zhuǎn)動(dòng)，則1=0。三、程序框圖輸入a,d, 1,輸入N作循環(huán)，
