基于ADAMS的行星轮系动力学仿真-郭会珍

:1004-2539(2013)05-0086-04ADAMS(,221116)由于行星轮系的结构复杂,难以利用理论方法研究行星轮系的动力学行为,寻找一种简便可靠的动力学行为研究方法来研究行星轮系的振动特性可靠性等具有重要的意义在对行星轮系进行三维参数化建模的基础上,利用机械系统动力学软件(ADAMS)建立了行星轮系的动力学模型,并对行星轮系的动力学行为进行了模拟结果表明,仿真和理论结果的误差为0.2%,证明所建动力学模型是可靠准确的;由于轮齿啮合的周期性致使轮系振动也具有周期性;行星轮轮齿间接触力满足力平衡关系,与理论分析相一致研究结果对行星轮系振动特性可靠性以及寿命等研究具有一定的指导意义行星轮系ADAMS接触力动力学仿真DynamicsSimulationofPlanetaryGearTrainbasedonADAMSGuoHuizhenTanChangjunChenJunfeng(SchoolofMechanicalandElectricalEngineering,ChinaUniversityofMiningandTechnology,Xuzhou221116,China)AbstractDuetothecomplexstructureoftheplanetarygeartrain,itisdifficulttotakeadvantageofthetheoret-icalmethodstostudythedynamicalbehaviorofplanetarygeartrain.Soitissignificanttofindasimple,reliabledy-namicsbehaviorresearchmethodtostudythevibrationcharacteristicsandreliabilityoftheplanetarygeartrain.Byus-ingADAMS,thedynamicsmodelofplanetarygeartrainisestablishedandthedynamicalbehaviorissimulatedbasedonthethree-dimensionalparametricmodeling.Theresultsshowthat,theerrorofsimulationandtheoryresultsis0.2%,whichprovesthatthedynamicsmodelisreliableandaccurate.Becauseoftheperiodicityofthegearmeshing,thegeartrainvibrationalsohasperiodicity.Thecontactforcesbetweentheplanetarygearteethmeettheforce-ba-lancerelationshipanditisconsistentwiththetheoreticalanalysis.Thestudyresultshavecertainguidingsignificanceforthevibrationcharacteristics,reliabilityandliferesearchoftheplanetarygeartrain.KeywordsPlanetarygeartrainADAMSContactforceDynamicssimulation0,,[1]3-5,,,,20,[2][3]1956-1964[4-5][6]71-73,ADAMS,,,11.1,18620131/mm/(b)916200.50924200.46964200.00Pro/E,,111.2Pro/EADAMS[7]15-16,:¹Pro/EParasolid,ADAMS;ºPro/EADAMSMechanism/Pro,,Pro/E,,,,,Pro/EADAMS,,Pro/E5.0ADAMS201022.1ADAMS,,,,[6]71-72:¹;º(Ground);»4;¼;½;¾4;¿;À22.2,ADAMS/View,(Restitution);(Impact),,Impact,:;[8]2F1=0K(q0-q)e-C(dqdt)STEP(q,q0-d,1,q0,0)q\q0qq0(1),K;q0,mm;q,mm;e;C;STEP;d,mm(Contact),Hertz[7]16-17Hertz,,D=a2R=(9P216RE2)13(2)PDP=KD3/2(3),K,K=43R12E,,1R=1R1+1R2,R1R21E=(1-L21)E1+(1-L22)R2,L1L2,E1E233.1150r/min(900(b)/s),T=7@105N#mm,t=1s,step=500GSTIFF,I3,0.001873705ADAMS3.2(1)3,3,,,,,,179.6219(b)/s,180(b)/s,0.2%,,34,0(b)/s2,,,,4,,,55,39.5Hz,40Hz,45(2)2K-H(A),g[1]136-145[3]1958-1959Fbg@Rg=Fag@Rg(4)Fbg=Fag(5)FHg=Fbg+Fag=2Fag(6),Fag,N;Fbg,N;FHg,N;Rg,m6Fag,7Fbg,67,,,,,2~3Fag179290N,23538.59N;Fbg15092.68N,0N,,,Fag64.19Hz,9615.15N;Fbg64.19Hz,829.36N,2.5Hz,40Hz,6731.69Hz63.75Hz,,[9]381-38212,31.69Hz6Fag7Fbg8(Fag+Fbg)FHgFagFbg,/E0/+08,8820136.32kN,JointFHg,6.18kN,,(3)[9]379-383[10-14],,t=10s,,,910910910,,,0~98kN,[9]381-382,;,,90b4Pro/EADAMS,,,,[1].[M].:,1994:3-5,136-145.[2],,.[J].,2002,38(2):44-48.[3],,.[J].,2009,20(16):1956-1964.[4],,.2K-H[J].:,2003,43(5):636-639.[5],,.[J].,2001,16(2):163-166.[6],,.[J].,2007(8):71-73.[7],,.ADAMS[J].,2005(3):15-17.[8].ADAMS[M].:,2010:91-92.[9],,.[J].,2011,42(2):379-383.[10],.[J].,2002,19(6):87-88.[11],,,.[J].,2007,19(4):901-904.[12],,.Pro/EADAMS[J].,2006,30(6):66-69.[13],.ADAMS[J].,2003,12(6):690-693.[14],.[M].:,1997:154-174.:20121017:20121130:(1988-),,,(上接第80页)B0B[1],.[J].,2006,30(3):37-39.[2],.[J].,2000,24(2):10-14.[3],,.[J].,2012,36(9):28-31.[4].[M],:,1990:138-166.:20121030:20121207:2012(120164020):(1987-),,,893705ADAMS
