4、構(gòu)的運(yùn)動(dòng)說明：凸輪運(yùn)動(dòng)分為四個(gè)階段：第一階段，推程階段：從動(dòng)件以等加等減規(guī)律運(yùn)動(dòng)，凸輪轉(zhuǎn)過角度為1500，擺桿上擺過240；第二階段（即遠(yuǎn)休止）凸輪轉(zhuǎn)過角度為200，擺桿靜止；第三階段（即回程段）從動(dòng)件以簡諧規(guī)律運(yùn)動(dòng)，凸輪轉(zhuǎn)過角度為1200，擺桿下擺過240；第四階段（即近休止）凸輪轉(zhuǎn)過角度為700，擺桿靜止。<二>機(jī)構(gòu)運(yùn)動(dòng)簡圖如下：四、機(jī)械原理課程設(shè)計(jì)方案以及原始數(shù)據(jù)<一>、設(shè)計(jì)方案：符號(hào)方案 01020304r0從動(dòng)桿運(yùn)動(dòng)規(guī)律推程回程24º150º20º120º70º40等加等減簡諧<二>、原始數(shù)據(jù)：凸輪

5、中心到擺桿中心的距離：a=160mm擺桿行程角：=24°凸輪推程運(yùn)動(dòng)角：01=150°凸輪遠(yuǎn)休止角：d02=20°凸輪回程運(yùn)動(dòng)角：03=120°凸輪近休止角：d04=70°基圓半徑：r0=40mm滾子半徑rr的選擇：凸輪工作廓線的曲率半徑表示為a ,用表示理論廓線的曲率半徑,即有a=±rr；為了避免發(fā)生失真現(xiàn)象，我們應(yīng)該使p的最小值大于0，即使rr ；另一方面，滾子的尺寸還受其強(qiáng)度和結(jié)構(gòu)的限制，不能太小，通常我們?nèi)L子半徑：rr=（0.1 0.5）*r0在此，可以取r1=0.25*r0=10mm。擺桿長度的選擇：擺動(dòng)推桿取許用壓力角a

6、= 35°45°因此桿長取150mm 五、圖解法設(shè)計(jì)擺桿的運(yùn)動(dòng)規(guī)律：（1） 第一個(gè)運(yùn)動(dòng)階段，推程段：擺桿推程運(yùn)動(dòng)是等加等減運(yùn)動(dòng)，根據(jù)多項(xiàng)式運(yùn)動(dòng)規(guī)律，推桿的多項(xiàng)式運(yùn)動(dòng)規(guī)律的一般表達(dá)式為=C0+C1+C22 +Cnn 式中為凸輪轉(zhuǎn)角；為擺桿位移； C0、C1、C2、Cn為待定系數(shù)，可利用邊界條件來確定。運(yùn)動(dòng)規(guī)律是二項(xiàng)式運(yùn)功規(guī)律，其表達(dá)式為=C0+C1+C22 由式可見，為了保證凸輪機(jī)構(gòu)運(yùn)動(dòng)的平穩(wěn)性，通常應(yīng)使推桿先作加速運(yùn)動(dòng)。設(shè)在加速段和減速段凸輪機(jī)構(gòu)的運(yùn)動(dòng)角及推桿的行程各占一半（即各為0/2及/2）。這時(shí)，推程加速段的邊界條件為 在始點(diǎn)處=00，=00， 在終點(diǎn)處=750，=1

7、20， 將其代入，可求得C0 =0 ,C1 =0, C2 =2/ (01 )2,且=240，故擺桿等加速推程段的運(yùn)動(dòng)方程為=22/(01 )2式中，變化范圍為00750。推程減速段的邊界條件為在始點(diǎn)處=750, =120,在終點(diǎn)處 =1500, =240,故擺桿等減速推程段的運(yùn)動(dòng)方程為=-2(01-)2/(01)2 式中的變化范圍為7501500。（2）第三階段，回程段：簡諧運(yùn)動(dòng)規(guī)律，其擺桿回程時(shí)的運(yùn)動(dòng)方程為=1+cos(/03)/2式中的變化范圍為17002900。（2） 第二、四階段分別是遠(yuǎn)休止和近休止，故擺桿運(yùn)動(dòng)方程都為=00 （3） 初始角：0=arccos(a2+l2-r0)/(2a

8、l)=arccos(1602+1502-402)/(2×160×150)=14.3620 取計(jì)算間隔為100計(jì)算各分點(diǎn)的位移值，其結(jié)果如表：凸輪運(yùn)動(dòng)角（0）擺桿轉(zhuǎn)角（0）0.00.00000010.00.21333320.00.85333330.01.92000040.03.41333350.05.33333360.07.68000070.010.45333380.013.54666790.016.320000100.018.666667110.020.586667120.022.080000130.023.146667140.023.786667150.024.00000

12、）時(shí)=01+02+03+4=29003600, =00。坐標(biāo)值對(duì)角的倒數(shù)為dx/d=a cos-lcos(+0)dy/d=-a sin+lsin(+0)第三階段按簡諧運(yùn)動(dòng)規(guī)律=01+02+3，3=001200,坐標(biāo)值對(duì)角的倒數(shù)為dx/d=acos-lcos(+0)(1-sin(3/03) /(203 )dy/d=a sin+lsin(+0) (1-sin(3/03) /(203 )則sin=(dx/d)/ (dx/d)2+(dy/d)21/2cos=(dy/d)/(dx/d)2+(dy/d)21/2 凸輪工作廓線的直角坐標(biāo) x=xr r cosy=yr r sin驗(yàn)證：根據(jù)尖底（滾子）擺動(dòng)從動(dòng)
