车辆转弯最小半径和通道宽度计算

1、车辆最小转弯半径和通道宽度计算情况1:普通货车转弯情况定义C=2m L=8m D=2m M=1.792m b=2.060m K=2.5m0=30 R1 = V(L+D)/tan 0 2+C2R2= V (L+D ) /tan 0 - ( K-M ) /22+L2 +b-M/2R3= (L+D ) /sin 0 = (8+2) /sin30R1 R2均比R3小,所以以R3为计算标准(路旁无阻挡物，可按R3= (L+D ) /sin 0 = (8+2) /sin30 =20mS= (L+D ) /tan 0 = (8+2) /tan30 =17.32mr=S-K=17.32-2.5=14.82m宽

2、度=R3-r= 20-14.82=5.18m转弯角度：。=Arctan L/ S-K-(K-M)/2 =27.8情况2:R2计算拖车主车短，副车长，转弯情况定义C=2m L=8m D=2m P=Q=0.5m U=4m E=1m K=2.5m M=1.792m b=2.060m9=30 R1 = V(L+D)/tan 0 2+C2R2= V (L+D ) /tan 0 - ( K-M ) /22+L2 +b-M/2R3= (L+D ) /sin 0 = (8+2) /sin30R4= / (L+D ) /tan 0 -K/2 2+ ( L+D+P ) 2 - (Q+U ) 2 +K/2 2+E2

3、R1 R2均比R3小，R4可控制 所以以R3为计算标准(情况不同取的转弯半径有所不同)R3= (L+D ) /sin 0 = (8+2) /sin30 =20mS= (L+D ) /tan 0 = (8+2) /tan30 =17.32mr=S-K=17.32-2.5=14.82m宽度=R3-r= 20-14.82=5.18mArctan (L+D+P ) /(r+K/2)=Arctan(8+2+0.5)/(14.82+1.25)=32.022Arctan(U+Q)/(r+K/2)=Arctan (4+0.5) /(14.82+1.25)=13.977 转弯角度：a = (32.022 +13

4、.977 ) =45.999 拖车主车长，副车短，转弯情况定义：C=2m L=8m D=2m P=Q=0.5m U=4m E=1m K=2.5m M=1.792m b=2.060mT=咱2+(1_+ D+P+Q+U+E) 2=v17.322+ (6+1+5 ) 2= v444 =21.07m宽度=T-r=21.07-14.82=6.2513m情况30=30验算未转弯时车头摆直需要的宽度:R1=L/sin什(b-M)/2=16.134mR 2= V (L+C) 2+L/tan什(K-M)/2 2 =17.376m(注意情况3与情况1, 2所设。不一样) 蓝色三角形长直角边为：L/tg 0 - M/2=17.32-1.792/2=12.96m蓝色三角行斜边为：412.96 2+ (2+0.5 ) 2=13.2m绿色三角形长直角边为：v13.2 2- (0.5+4 ) 2=12.4mr=R2-r=12.4-2.5/2=11.16m道路宽度=17.376-11.16=6.22m车的转弯角度为：arccos12.96/13.2+arcsin4.5/13.2=11 +20 =31 验算未
