汽车离合器基本参数的优化设计

20006June,2000132JournalofShiyanTechnicalInstituteVol.13No.2王　萌(,442000)[]　汽车离合器的基本参数主要有离合器的后备系数、摩擦面单位面积上的压力p0、摩擦片外径D和内径d等,这些参数的变化直接影响离合器的结构尺寸和工作性能。本文采用优化设计方法来确定最佳的离合器基本参数,实例计算表明了该方法的实用性。[]离合器;基本参数;优化设计[]U463.211[]A[]1008-4738(2000)02-0046-041,,,,;,,;,,;,,2,:Tc=fFZRc(1),Tc(Nm);f;F(N);Rc(m);Z,:Rc=D3-d33(D2-d2)=D2+Dd+d23(D+d)(2)F=p0A=p0(D2-d2)4(3)46[]2000-03-15[](1976),,,p0(N/m2);A(m2);D(m);d(m)(2)(3)(1):Tc=12fZp0D3(1-c3)(4),c,c=d/D,Tc,:Tc=Temax(5),Temax(Nm);,1,p0dD,,1p0,,p021=1.21.75=1.52.25=1.84.02p0p0=0.100.35MPap0=0.350.60MPap0=0.701.50MPa,Temax,(1)(5),p0,D,d,,,,33.1(1)(5),FDdp0(3),p0FDd,:X=[x1x2x3]T=[FDd]T(6)47汽车离合器基本参数的优化设计,,:F(x)=min[4(x22-x32)]=min[4(D2-d2)](7)3.2(1)c0.530.7:g1(X)=[-x3/x2]+0.530(8)g2(X)=[x3/x2]-0.70(9)(2)DVD70m/s,:VD=60nemaxD10-370,nemax(r/min):g3(X)=[(nemaxx2)10-3/60]-700(10)(3),,(1):g4(X)={-fZx1(x23-x33)/[3Temax(x22-x32)]}+L0(11)g5(X)={fZx1(x23-x33)/[3Temax(x22-x32)]}-H0(12),H,L(4),,p0,(2):g6(X)={-4x1/[(x22-x32)]}+pL0(13)g7(X)={4x1/[(x22-x32)]}-pH0(14),pHp0,pLp0(5),dD0:g8(X)=(-x3)+(D0+50)0(15)(6),,:w=4WZ(D2-d2)[w](16),w(J/m2);[w],:[w]=40104J/m2,:[w]=33104J/m2,:[w]=25104J/m2;W(J),:W=2ne2180marr2i02ig2(17),ma(kg);rr(m);ig;i0;ne,2000r/min,1500r/min:g9(X)={ne2ma2rr2/[45Zi02ig2(x22-x32)]}-[w]0(18)3.3,9[(8)(15)(18)]1[(7)]48200021323,:minF(X)=(x22-x23)/4(19)X=[x1,x2,x3]T(20)s.tgi(X)0;i=1,2,9(21),:(X,M(k))=F(X)-M(k)9i=1(1/gi(X))(22),M(k),4:Nemax=6000r/min,Temax=145Nm,f=0.25,Z=2,i1=3.545,i0=3.889,rr=0.314m,D0=0.80m,ma=1710kg3,,,3F(N)D(m)d(m)57000.2280.15056000.2220.146[][1].[M].:,1995.[2].[M].:,2000.[3].[M].:,1994.AnoptimumdesignofthebasicparametersofclutchesWANGMeng(Dept.ofMechanicalEng.,ShiyanTechnicalInstitute,ShiyanHubei442000)Abstract:Thebasicparametersofclutcharethebackupcoefficient,thepressureperunitareaoffrictionplanep0,theouterdiameteroffrictionplateD,theinnerdiameteroffrictionplated,etc.Theseparametersaffectthestructuredimensionandperformanceofclutchdirectly.Thispaperdeterminestheoptimalbasicparametersofclutchwithoptimummethod.Thepracticabilityofoptimummethodistestifiedbytheexample.Keywords:clutch;basicparameters;optimumdesign49汽车离合器基本参数的优化设计
